Varify that the lamp door is totaly closed and tight. The door switches do not tell the Main Micro. the door is closed unless door is flush
with rear cabinet.
Hope this helps,

The tv is only 4 years old and just stopped working while we were watching it. it is a "52 model number pt-52lcx65-ka.


Hi,
If lamp in tv has not been replaced in last 3-4 years then check lamp and replace it.
Did tv showed lamp replacement requires warning/ message on screen before going to shut down?
Did you hear any pop sound inside tv when it get shut down? that pop sound could be lamp that got broken.
Let me know if you have additional question.
Thanks.

Heard a pop, tv went off, then doesnt come back on


Your unit has some sort of PSU fault, or a problem that is shutting down the Power Supply Unit, PSU. This happens so that no further damage, and possible fire will occur. The sound is it starting up, shutting down, over and over.

You need to take the unit to a reputable service centre/man and ask for a firm "Quote" for the work to be done.

This unit probably has a bad power supply. It may also be shutting down because if this unit has recorded 5 lamp errors it goes into shut down. To eliminate lamp errors you can force the unit on in the service mode and look for lamp errors. To do this, you unplug the unit, and while depressing the volume up and channel down buttons at the same time, plug the unit in. Hold for 1 second and release. The unit will then power on and a small k should appear on the screen. If this does not happen then there is definately an internal failure that will require a sharp auth. service center. If the unit does come on with the k, use the remote and press the channel up button. This will produce a menu on the screen and you will note on line will indicate lamp errors. On the right side of that line will show the # of lamp errors. If it reads 0, lamp errors are not the issue, however if it reads 5, you can highlight that line by using the channel down button. Then use the curser right arrow to select the error and then again to reset them. Once the lamp errors have been reset to 0, unplug the unit and wait at least 25 seconds before plugging in. The unit will now power up normally and this may cure the problem for good. If this process corrects the problem and it occurs some time later or right away that will be an indication that either the unit has bad backlights or inverter has failed and will again require service.

Replaced lamp and now can't get a picture


Hi Sally Jo, Unit powers on and works properly for a while then shuts off with a red lamp LED (lamp error). Suspect bad lamp part # 915P020010 2. Lamp enable line at J14 pin 6 does not switch to 5 volts after turn on, 12 and 5 volt supplies are good. Suspect the Light Engine part # 939P977010 3. At power on the lamp turns on and off three times and then the unit shuts down with a red lamp LED (lamp error). Replace the Light Engine part # 939P977010 4. Check for 12-volts DC at J-9 connector pin 4 on the Engine Driver PCB, if missing check for an open F9A09 on the Power PCB, if it is open replace F9A09 part # 283P127060 and the Light Engine part # 939P977010 5. Lamp enable line at connector J14 pin 6 on the Engine Driver PCB switches to 5 volts after turn on but does not go back to 0-volts (low) after 5 seconds, 12 and 5 volt supplies are good. Suspect the Light Engine part # 939P977010 6. Check for 5-volts DC at J-9 connector pin 1 and 2 on the Engine Driver PCB if missing replace the Power PCB part # 934C148001. Hope this helps!
