Most projectors require you to reset the lamp operating time counter to 0 after changing the light. If the counter is not reset, the projector may prematurely indicate that the replacement light is worn out or may even refuse to turn on. You can either follow the procedures below or consult your projector’s manual to learn how to reset the light counter.
Never swap out the lamp before resetting the counter. We advise that you order a new lamp right away even if your old one is still shining brightly and the projector is beginning to suggest that its life is about to expire. Install the new lamp as soon as it is delivered, and save the old one as a backup. It is recommended to avoid exceeding the bulb’s lifespan because doing so considerably increases the risk of explosions.

How do you know when to change a DLP bulb?
Fortunately, there are some indicators that the projector bulb needs to be changed. In order to make sure your projector is in functioning order, be aware of these symptoms.
Loss of Image
You have an issue if you switch on the projector and nothing appears. It’s likely that your bulb has burned out and you need to buy a new projector lamp. You might see the image fading before the bulb burns out. The luster or brilliance starts to wane. A dull image can be adjusted by the human eye, making an issue go unnoticed. Attempt raising the color settings on your projector. The bulb has to be changed if the image remains faint or stays the same.
Flickering Image
Have you seen any flickering in the projector’s images? This is yet another indication that your bulb is on the verge of burning out. Using a projector lamp that is not an OEM projector lamp can result in a faulty bulb, which is another possibility.
An Indicator on the Projector
Nowadays, a lot of projectors and DLP televisions incorporate an indicator that illuminates when the light needs to be replaced. This can appear as a flashing red or yellow warning or as a bulb icon on the display. If you’re unsure of where the indicator is, refer to the projector’s instruction manual.
The projector can be used till the bulb burns out. Over time, you’ll start to notice a degraded image. Before the projector bulb burns out, we advise changing it.
Color Loss
A powerful bulb is necessary for the color wheel within a DLP projector to function properly. When you need a new bulb, the wheel and DMD chip cannot accurately show colors. Another indication that your projector bulb needs to be replaced is fading colors or colors that look odd or muddy.
How can you tell if the bulb in your TV has burnt out?
Symptoms and Signs The screen may go dark and you may hear a popping sound if your lamp suddenly goes out. Your television will still be audible, but the picture won’t be visible. To prevent you from being without a TV, some TV manufacturers incorporate a warning to change the light when it begins to burn out.
How much does a TV lamp replacement cost?
Replacement of a TV motherboard ranges in price from $200 to $350, or roughly $275 on average. Replacement motherboard parts can cost between $35 and $199, and labor can cost between $60 and $125.
TV Inverter Repair
A TV with one inverter board or two inverter boards will typically cost $138 or $178 to repair its inverter, with costs ranging from $104 to $171 for supplies and labor. The typical labor rate for fixing TV inverters is $97 per hour, and part prices range from $7 to $74.
A TV’s inverter board’s job is to supply electricity for the screen’s backlight. A few hundred volts are needed to power the inverter board. The TV would turn on and have sound but no picture if the inverter board malfunctioned.
Inverter parts are typically replaced rather than repaired when they break. When a converter board’s capacitors malfunction, a technician may be able to resolve the issue without having to replace the entire inverter part. Replacing the capacitors may be the sole TV inverter repair option if a whole inverter board replacement is not offered for the model of TV being repaired.
TV Bulb Replacement
Between $60 and $115 is required to repair a flat-screen TV bulb, with the average homeowner paying $84 for components and labor. Replacement bulbs can cost anything between $18.50 and $80.
Older LCD or projection TVs that turn on with sound but no picture may have burned-out lamps, which is a common and expected occurrence. In this instance, changing the bulb will solve the issue. The bulb should be simple and quick to replace for a skilled technician.
Samsung 50-inch HDTVs with back projection (1080 megapixel) employ specialist LED light modules with replaceable bulbs.
Backlight Repair Cost
A repair service will charge between $100 and $122 to fix a TV’s backlight, including labor and replacement parts. Due to trip expenses, in-house repairs are more expensive. For each LED, new backlight parts cost on average $2.50, and for each CCFL strip, they cost between $20 and $25.
A technician can switch your TV’s backlight from CCFL to LED using the same amount of backlighting strips if the CCFL strips are no longer available. LED strips range in price from $12 to $30.
The cost of a new inverter, which ranges from $7 to 74 before labor and averages $40, may be required to power the LEDs. In some circumstances, a repair business is able to upgrade a CCFL backlight to LED without needing to set up a new inverter.
A TV’s backlight malfunction could potentially be caused by the power inverter that powers the backlight malfunctioning. Rarely, both the inverter and the lighting parts malfunction.
Power Supply Board Repair Cost
For just the parts, repairing a TV power supply board can cost between $23 and $234. The parts and labor for completely changing the power supply board come to $250. Replacement capacitors are inexpensive if only one has failed. However, replacing the entire board is more economical for the technician than having to identify and fix each bad capacitor individually.
HDMI Port and Circuit Board Repair
A TV’s HDMI port can be fixed for $93 to $302. In some circumstances, it may be necessary to replace the input circuit board to which the HDMI port is connected. This input circuit board replacement will set you back between $200 and $350 in total.
TV Capacitor Repair
Repairing a TV capacitor ranges from $60 to $129, components and labor included. The price of the new item is between $0.06 and $14, and the labor cost is between $60 and $125 per hour. TV capacitors filter signals, make channel switching easier, and prevent the circuit from receiving too much power.
When a TV capacitor fails, it cannot be repaired; it must be replaced. A blown capacitor will cause your TV to cease working while it is in use and give off an ammonia or bleach-like odor. Some capacitors, nevertheless, don’t emit any discernible odors when they blow.
Replacement Glass
There is no glass replacement for flat screens. Optical glass glue, which costs $1.70 for a 5-ml tube, is the only alternative for repairing flat-screen TV glass. If the crack is simply a few inches long or less, this can be a possibility for TV glass repair. Glass is attached to the display panel as a single unit during the manufacturing process of TV panels.
Picture Tube
Depending on the size of the TV and the location of the repair, a TV image tube can be fixed for anywhere from $149 and $249 on average.
- CRT repairs done at home cost between $199 and $249. For TVs with a picture tube size of 27 inches or less, the cost of repair is $199; for TVs with a picture tube size of 28 inches or more, the cost is $249.
- In a repair business, a TV with a screen size of 27 inches or less will cost $149 to fix, whereas a TV with a screen size of 28 inches or more will cost $199.
Older TVs, often known as picture tubes or cathode-ray tubes (CRTs), had far worse image quality than modern TVs and were also much bigger and heavier.
Fuse Repair
Between $61 and $136 is required to fix a TV fuse, with the majority spending, on average, $99. The price of the replacement fuse ranges from $1.50 to $11, while the hourly rate for labor is between $60 and $125. There can be additional charges.
Panel Repair Cost
LCD flat-panel repairs are not thought to be economical. It is less expensive to replace the entire TV than to repair or replace the display panel if the glass is cracked or the screen is physically harmed.
Can the TV’s lighting be changed?
Yes. A broken TV backlight is rather simple to replace. A screwdriver, wires, a soldering iron, and LED flexible strips are all that are required.
How can I tell if my Mitsubishi DLP light needs to be repaired?
The majority of issues with these TVs are caused by light issues.
Simply select the relevant link for your Hitachi, JVC, Mitsubishi, Sony, or Toshiba TV to get assistance specific to that brand.
General lamp information:
Only TVs that use LCoS projection, like the Sony SXRD and JVC HD-ILA models, LCD projection, or DLP projection need projection lamps. These are large-screen tabletop televisions with typically 46″ or larger screens (and one 37″ Sony model). Projection bulbs are frequently included in small projector devices that display on different screens. With just a screwdriver, a client may quickly replace a projection lamp. In the event that a unique tool is needed, it is delivered with the replacement lamp. Flat panel TVs (plasma, LCD, and LED TVs), conventional direct-view TVs, and the classic floor-standing projection TVs do not have changeable lamps.
When you use the TV remote to access the TV menu (not the satellite or cable TV guide), the volume display, channel display, input display, etc., you are utilizing an OSD (On-Screen Display), which is a pattern that the TV internally generates on the screen. The lamp is okay if you can see an OSD.
A dead lamp can typically be identified visually.
A little glass tube is present inside each lamp.
This tube is defective if it is broken or if a hole has melted in it.
When the lamp goes out, viewers frequently hear a “pop.”
Another red flag for a poor lamp is if the outside glass envelope has a crack, blister, or discolouration.
Rarely will a light malfunction without any obvious internal damage.
This can only be verified by using a quality lamp in its place.
The surplus high voltage that is drained off when a lamp doesn’t illuminate can cause the lamp power supply to buzz or arc.
On TVs that repeatedly resume, this buzzing could be audible after each restart.
This noise may also be a sign of a malfunctioning lamp.
Weak lamps can also blank out while the set is operating, although bad lamps typically fail to illuminate when the set is turned on.
If the set notices this, it can try to turn the lamp back on.
The lamp is probably to blame if the picture and all OSDs intermittently go out.
JVC:
There is no picture or OSD when the TV first turns on. The front panel’s blue and orange lights eventually begin to flicker together, continuously, and twice every second.
Mitsubishi:
TV displays a dark screen during startup, with no picture or OSD. The LAMP light will start to illuminate after a short while and remain red throughout.
Symptom 2: (On some models) The TV is functional, however the LAMP lights are continuously yellow.
This serves as a warning that the lamp may soon fail after being used for a specific amount of hours.
In order to make the warning light go out after you replace the lamp, you must reset the lamp timer, according to an on-screen message.
Symptom 3: The image flickers, flashes, or changes color (on some models).
The set can shut down after a while.
Mitsubishi first produced bulbs for these models with yellow reflectors.
They now offer silver-colored lighting after learning that they could result in a variety of odd symptoms.
Certain aftermarket bulbs will also contribute to this issue.
Try an original lamp that you bought from Mitsubishi or from us if your set has a yellow lamp or if you recently replaced the lamp.
There is no assurance that your replacement lamp is a genuine Mitsubishi lamp unless it originates from Mitsubishi, even if it was labeled with the original Mitsubishi component number.
Sony:
Symptom 1: The screen is dark with no picture and no OSD, yet the green POWER light flashes once every second (the typical startup indicator). The red LAMP light begins blinking after the set tries to restart three more times.
Symptom 2: The TV is functional, however the screen goes black and there is no OSD or visual.
The picture eventually turns back on by itself after a little while, however it keeps turning on and off by itself.
While the picture is out, the green POWER light blinks continually, and sound may or may not be present.
Symptom 3: The television is functional, but each time it is turned on, a lamp warning message is displayed on the screen.
Toshiba:
The screen is dark with no picture and no OSD, however the red light on the front panel blinks three times per second and the green light comes on continuously. The television turns off and resets itself eight times. Then, both the green and red lights begin to blink once every second.
On a Mitsubishi DLP TV, where is the reset button located?
Resetting a Mitsubishi TV
- Pushing on the front panel will make it open.
- Push the “System Reset” button using a pointed instrument, like the tip of a paper clip or the sharpened end of a pencil.
- Wait until the green LED light on the front panel display stops flashing, which should take around a minute.
Why won’t my Mitsubishi TV power on?
Try resetting by plugging in and plugging out the power or pressing and holding the POWER button for 10 seconds. If there is no assistance, a technician will need to fix the TV.
What happens if I don’t change the light in the projector?
It’s possible that your present lamp will blow up, perhaps harming the projector’s blowers, fans, colorwheel, and optics. When you switch out the old lamp for the new one, you must reset the timer.
