Lamp won't turn on

My DLP HDTV lamp was busted.I replaced it with new replacement part, but
the lamp won't turn on. I checked the power to the lamp ballast( it is only 10V)
The power supply has 110V input, but the output going to the lamp ballast is only 10V. What is supposed to be problem? Could it be the power supply? If so where can I find the part supplier for this. Thanks

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

Hi! there are many causes why your lamp went off its either that the ballast is defective or the lamp itself is busted, but most dlp and lcos type of tv the lamp is culprit. because lamp lifespan is only 5000 to 1000hrs used only.

Tv turns on for one second then turns back off

I believe it is a Back Light failure. Either because of a bad Ballast, a Power Supply, or a bad Lamp that is not replaceable. If it is a bad Ballast or Power Supply they are replaceable. Checking the Voltage from the Power Supply for the Ballast will tell if the Power Supply is bad. It should read around 250V to 300V.
If the Voltage is there, the LCD Panel will probably need to be replaced. I recommend a professional to evaluate it to be sure.
I hope this helps,

TV will not power on.

I guess your TV is DLP.
Please notice the follow symthoms:
When you on TV, did you hear some strange noise from the back of the TV. If yes, the color wheel needs replacing.
If no, check the lamp. Take a look to bottom of lamp, you will see white pot or sometime a pop up there due to lamp cycle is going to end. When changing lamp, check the ballast and power sup, too. If you see caps are poping up. Pull out those board and replace the poped caps.
