Replacement of Lamp

Have had my lamp replaced twice in last 9 months and I suspect problem was not the lamp but something in circuit board. How do I open unit to remove the lamp myself? Is it difficult?

Lights flash then powers down.


Before read this, keep in mind that this is not your model and parts are not the same. This is just to let you know the steps to take. Sorry don't have the schematic for your set, but maybe this will help in checking. I'm Ex-Army myself and Veteran of OIF and OEF.::::1. (Lamp may light and go out) suspect bad lamp part # 915P020010 2. 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 3. (Lamp may light and go out) Check for 5-volts DC at J-9 connector pin 1 and 2 on the Engine Driver PCB if low or missing check C9A37 and C9A38 both 3300 UFD 10 V on the Power PCB (part # 930B921002) 4. 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 5. 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 6. Lamp enable line at connector J14 pin 6 on the Engine Driver PCB switches to 5 volts after turn on and does go to 0-volts (low) after 5 seconds, 12 and 5 volt supplies are good. Suspect the Lamp Power PCB (ballast) part # 939P978010 7. 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

Bulb burned out in 1 month


Your lucky it lasted 1 month. The population thinks they are receiving inexpensive items from China. Instead they are cheap useless rubbish. You will find that anything from Asia costs half as much and only lasts 1 tenth of the time. DO THE MATHS PEOPLE WE ARE BEING RIPPED OFF. While Asia is getting rich.

Toshiba 52hm95 lamp breaks after only weeks of use


It is as far as the set is concerned, it sees the lamp not on.

Most likely cause would be the lamp ballast that drives the lamp.

Sony KDS-XBR60 lamp burnout twice


I would suspect the ballast that powers the lamp may be bad.

It would be a good idea at this point to Call Sony customer service to see if this issue in this model is in their extensive data base of problems/answers by model number.

My tv mitsubishi wd-60735 turns on for about 2 min. then shuts off and red lamp light turns on,,,The lamp is only 3 months old.. Do I just need to replace bulb again or is it something else???


Don't know if this applys to you but if you have purchased anything but Osram or Philips replacement lamp for your DLP tv then this is probably your problem.. The generic is VERY tempting in this recession but in this case generic is poison to your dlp tv... i have a Mitsubishi 60735 and went thru 2 generic bulbs when my tv kept shutting down on it's own and the lights on front would flash, i could cut it back on for 10 minutes then flicker and shut down again ..well since the bulb was new i thought it may be defective so i got is exchanged for another one ... after all of the post i have seen how much repairs were going to cost on dlp sets no matter what the problem was ..i was ready to chunk the tv out the door when the second lamp was doing the same thing.....!! well a last ditch effort to save my tv before i trashed it or taking it apart to dissect it.. was to buy a brandname lamp ... in my case i purchased a Philips ..it cost twice as much =/ ..i could just return it if it didn't work.. well it was the generic lamps that was causing trouble.. the brandname worked perfectly .. i am just glad the generic lamp didn't do any damage to my TV!!! I have done further research on the generic lamps and realized that the damage it could have done was not worth the money i saved when i purchesed it... Generic is a great deal In some cases (household cleaners, etc..) but in this case GET THE NAME BRAND!!!! the only name brands i know of for these lamps are Philips or Osram/Sylvania.. hope this helps others from this headache. Do your research don't by generic lamp replacements, your DLP set cost to much to risk it.

Replacement bulbs burn out within a month


If you did not purchase the OEM Sony manufactured bulb (model LMP-H200) then you likely acquired a poor quality "after market" lamp. I recently purchased a replacement lamp for my VW60. The list price is $369, I paid $269 from a reputable brick and mortal / on-line retailer.

If you paid substantially less than $269 or bought from an unknown on-line seller, your lamp is likely the problem. Note I have seen some shady on-line sellers (with "electric" in their name) sell knock of bulbs for the same price as the OEM.

Hope this helps.

Sony sxrd bulb doesnt last 9blinks


IF SET HAS ERROR 9 THEN THE S1 and S2 board ARE PROBABLY THE REASON. DID YOU USE ORIGINAL SONY LAMPS ? GENERIC LAMPS (ESPECIALLY IN SONY) DON'T LAST. AND IS THE SET IN A CABINET ? I HAVE ALSO SEEN PROBLEMS WITH THE FANS GETTING DUSTY AND THE VENTS ON THE SIDE OF THE SET FILLED WITH DUST.
