How do I fix a flat screen tv that powers down within seconds of powering up?


The ballast may be going out. That is the board that the lamp wires connect to.. The power supply board may have a few components starting to fail as well.

Dlp lamps burn out quickly


you may have an issue with the ballast module for this DLP tv, that module has the two large red wires that connect to the lamp socket. check the 47MFD 450V capacitor on this module. If swollen replace the part, but also check the large electrolytic capacitors, two of them on the power supply module, where you power cord attaches, one or both of these may be damaged if the 47 MFD on the ballast module has failed.
You will need soldering skills for this repair.
If the fans are ladden with dust, this could also cause premature lamp failure, these lamps require clear ventilation, overheating is the enemy!

I have a 2006 Thomson/RCA ModelM50WH72S TV that we have replaced the lamp, it still does not work and a technician has told us that we need a light engine for it. How can we locate one?


have the same tv,, power light blinks, book said it was bulb, bulb didnt fix it,took it to tv repair shop, they found a bad capacitor, replaced it with a higher heat range capacitor, this capacitor was on the power board for the lamp circuit, repair was $200, not bad since i paid $1500 for the tv, other than that issue, just replaced a couple of lamps

Set is an LG DLP model RU 52SZ51D. Set sometimes needs to power cycle 20 or more times to fire up. Other times 1 or 2. The red led turns to amber and flashes approx 55 times and then turns to red and...


I need to know titles of lights that blinks on tv while it trying to power up. There are Power, Lamp and Temp lights, let me know what light blinks, this will help me to diagnose the problem as I hate to guess like try this and try that.
Thanks.

Check fan # 2


Samsung Consumer LCD tv's do not have fans except on the higher end models. The Commercial models do. Yours is a Consumer model. I suspect that you have a DLP tv. In that case replace the Lamp Fan. It is the Larger of the three fans. With the rear cover off, you will see a Blue switch lever on the lower right side of the tv. Hold it in a up position and turn "on" the set with your tv remote. Then look for any fan that is not running. Then order that fan. there is a large fan that cools the Lamp. The other fans are of the same smaller size and one cools the DND chip and the other cools the Ballast.
