Tip

Pix shuts off, green light starts flashing, pix comes back and shuts off again


If you have an issue where your picture turns off and the green power light starts flashing, you are most likely looking at a weak or old lamp. Do not be confused with a pix loss and a RED light flashing, as this can be caused by many things. The normal sequence of events for this fix is this:
1) TV turns on normally, plays for 1 to 3 minutes (may be more or less time)
2) Picture goes out and green power light begins flashing. It may flash for up to 2 minutes
3) green light turns on solid (stops flashing) and picture returns.
4) Picture goes out again and process repeats.

You may have been told that "if the lamp light isn't on, it isn't a bad lamp".
FALSE!
A weak lamp will cause the process above to occur. Other signs of a weak lamp:
The reflector in the lamp is very cloudy
You may see a "growth" or "bubble" on the vertical glass tube which is the lamp
You haven't replaced the lamp in quite some time or it is the original lamp from when you purchased the TV.

In cases like these, try a new lamp. Stick with an original Sony lamp, as there are many stories (both personally witnessed by me and also documented on the web) about problems with after market replacement lamps. And remember, lamps DO NOT have a shelf life; you can store them in a good environment (not too hot or cold!) for an indefinite period with no ill effects.

Samsung HLP4674W - changed bulb - still no picture - lights flash


If the lamp has been replaced I would think the Lamp ballast would be most likliest followed by the color wheel and then the Digital board. You can get any part needed for your model at www.tvrepairworld.com just leave them a email they respond quickly.

DLP TV starts to loose picture after 1 - 1/2 hours of use


This tv has a 3 board video path. Analog main pcb --->Digital main pcb --->DMD pcb. see which inputs have the problem to narrow it down. if only some inputs, suspect analog board. if everything flickers(all inputs and menu), suspect the dmd or engine. you can see the lamp shine out the back. if the lamp is flickering, suspect lamp or ballast.

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.
