Re: no picture

My too, same problem - tried replacing lamp ($150), no luck, replaced ballast ($200) no luck, replaced power supply ($150) no luck and TSC is telling me to replace the main engine ($600) - way too much for this piece of junk (cost me $4000 in 2005) - don't buy optoma products!!!

No sound or picture. red timer light on. wd60735

Hi there,

This model as 3 LED indicator lights:

1) Power/Timer 2) Status 3) Lamp

If "STATUS" LED is blinking RED:

1) Internal Fan has stopped. These tv's require fans, to prevent overheating and causing damage.

If "STATUS" LED is solid RED:

1) Circuit failure (short)
2) Disconnected DVI cable, chassis to engine
3) No LAMP-EN signal from Engine to turn the lamp On.
4) Ballast UART communication problem.

If "LAMP" LED is solid RED:

1) Lamp Failure - Lamp failed to turn On.
2) Lamp is broken (e.g. burst or blown)
3) Lamp turns Off during P-ON

There is no data relating to TIMER LED being solid RED.

Hope this helps.

I need to change the bulb in my WD65731 dlp tv. I have taken the cartridge out. How do I get to the bulb. I repleced my lamp and still have no picture. Am still getting a "blinking" lamp light on front...

The blinking lamp light refers to the lamp door not being closed. There is a little lever behind the main panel and if that's not shut, the lever won't be pressed in and therefore the light blinks. If it's a failed lamp, the lamp indicator light will be a solid, not blinking.

Replaced bulb stil issues

In most projection televisions if a solid light comes on there isn't anything wrong the bulb there is a problem with one of several cards in the back of the television. I'd check for over heating damage on your imput cards, the Controller card that is connected to said input card, or the relay card that controls the tube output. Keep in mind you did order a part off of Ebay which is untrustworthy in and unto its self.

After lamp replacement

Sounds like the plug is not making a good connection needs to be seated better.

No Picture

its probably the ballast that is bad, call Optoma and you can buy a ballast for it, but you will probably want to have a pro do it, changing the ballast is a lot more involved than just changing the bulb, the ballast is what powers the bulb and it does go out on occasion.

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!
