If the lamp is a known good one, the next most likely suspects are the lamp ballast/power supply board or a mis-aligned lamp door. There's an interlock switch which opens when the lamp door is removed. Try removing and re-installing the lamp and the door.

Samsung HLR5667wx/xaa. Power surge took out tv. Replaced bulb and the bulb works, but tv wont come on and lamp light is flashing.


Hello, it sounds like the color wheel may have failed. Was there any noises, like a high pitch sound before it went out? If the color wheel isn't turning at proper speed, the set won't start up by shutting down the lamp protection circuit.

I heard a pop on the Toshiba rear projection TV (model #62hmx84) and immediately lost the picture


Sir the problem of your unit is the lamp try to replace it it is much better to use a gloves and wash your hand after replacing the lamp because this lamp contains mercury. follow this steps.
1. Unplug the unit to main ac outlet. Remove the bulb housing cover from the back of the TV. Using a screwdriver, carefully remove the cover to reveal the old bulb. Using a cloth, remove the bulb from the TV by first unplugging it from the wiring harness. Carefully rock the harness back and forth until it comes free from the bulb. Push in the bulb slightly and turn it a quarter-turn to remove it from the bulb housing.
2. Install the new bulb. Do not touch the new bulb with your fingers, as any grease or fingerprint from your hands will damage the tiny mirrors in the bulb. Instead, carefully handle the bulb using the cloth. Insert it into the bulb housing and secure the door. Test the unit. Plug in and turn on your Toshiba TV and make sure that the new bulb is installed properly and that the image looks crisp.

3.
Reset the lamp time counter. Each Toshiba TV comes with a lamp hour meter stored in its software. If you do not reset the lamp timer, the unit may stop operating when it gets to a certain time (refer to your manual because each Toshiba TV is slightly different). To reset your Toshiba lamp timer, turn off the TV, wait 10 seconds, hold down the "on," "menu" and "input" buttons on the remote at the same time, and turn the power back on. A yellow light should appear in the bottom corner of the TV indicating that the lamp timer has been reset.
Hope this help good day and best regards.

I have a hitachi 55vs69 projection television. Lately, it has been shutting down every 15 minutes or so. The screen turns dark but you can still hear video until about a couple minutes later the led light...


Hi,

First step is to unplug the 120 vac power for a few minutes to clear any corrupted data that may be present in the controller circuits.

If a "power" reset doesn't help and the lamp or bulb is installed correctly, you most likely have a failed replacement bulb. The symptoms are all standard indications of a failed bulb.

Reduced lamp life can be caused by:
  1. Lightning and other 120 vac power bumps.
  2. Collisions with vacuum cleaners or other incidental impacts while the TV bulb is operating.
  3. Starting the TV without a complete cool down. Bulb will consume a small amount of mercury with each start. Excessive consumption occurs when bulb is "Hot" and turned on.
  4. Wrong bulb installed as replacement.(Philips original replaced with Osram or El Cheapo)
  5. Poor quality or damaged bulb installed as replacement.
  6. Bulb damaged during replacement
  7. Bulb installed incorrectly at replacement.
Almost all Hitachi 55vs69 "No Picture" failures are related to the bulb.

Many of our service events are with customers that purchased El Cheapo bulbs from "shopping cart" websites or picked up a bulb from a small "local" TV shop. Many small shops stock of 3 or 4 bulbs and try to substitute or cross reference to fit more than 200 models of TVs from 7 different manufacturers. If a premature bulb failure occurs, they have the opportunity to sell you some expensive service.

Go here to see all of the different Hitachi TV bulbs that are available in Canada.

Use the correct bulb for your model and if you are uncomfortable with the replacement procedure, get local service.

KDF46E2000 - Change Lamp Warning - Reset

Bulb is most likely OK. Original bulb in Sony TV is Philips, label on bulb usually says Philips. Sony don't make bulbs. Sony Cost is usually 1.5 times other sources. Many shopping cart operations sell condemned, reject or poor quality electronic service items because cost of return and fooling with them is excessive. This is obvious and widespread with convergence ICs and other parts.

Lamp timer needs reset. This is usually an automatic function. TV detects Increased lamp current from previous failed bulb or weak bulb condition and resets automatically. TV must be unplugged for lamp replacement for this to work. Occasionally it must be reset manually, as below:

1. TV must be in standby mode. (Power off).
2. Press the following buttons on the Remote Commander within a
second of each other:
DISPLAY Channel 5 Volume + POWER .1. Access Service Adjustment Mode and select the Service Menu that
contains the Category with the Adjustment Item you want to change.
2. To change the Category, press 2 or 5 on the Remote Commander.
Note: Pressing 2 or 5 only changes the categories within the
Service Menu displayed. To change a Category on one of the other
Service Menus, press the JUMP button until the correct Service
Menu is displayed.
3. To change the Adjustment Item, press 1 or 4 on the Remote
Commander.
4. To change the Data Value, press 3 or 6 on the Remote
Commander.
Note: To go back to the last saved Data Value, press 0 then ENT
on the Remote Commander to read the memory.
5. To save the changes, press MUTING then ENT to write into
memory.
6. To exit service mode, turn the power off by pressing POWER .
Wait 2 minutes before restarting the set to allow the fans to
completely shut down or the Service Menu will appear on the screen.

Place heat shielding around the lamp to prevent overheat; use cooling spray (freon) to cool any chips or, circuit boards near the lamp as you attempt to start the set check the lamp for the correct serial # voltage etc.

Samsung 50" DLP - Lamp Light Blinking after bulb replacement


Listen closely. The tv should make a high pitch whine as it turns on. If it does wait and see if it tries this a few times. If yes then check the bulb, I have seen cases where the lamp shoves the power connector back into the set. If the tv starts with a grown or heavy vibration noise, then your color wheel may have broken and needs replaced.
