It is quite important that you need to open the set for a proper diagnosis. As you switch the TV on the power supply section seems to boots up- the SMPS Unit. Now the processor seems to works as it decides to shut OFF due to a failure of the feedback voltage . This confirms that the output sections have a faulty drive which can also be a short in the output drivers. If so you might have to trace up the +B voltages from the main power to the outputs.
A possible short can be easily determined with a continuity test, make sure that the power plug is taken off and the capacitors are discharged before you attempt to test these circuits.-- not to damage your multimeter.
Disconnect the line feeder to the suspected shorted component to confirm.
Make sure there are no dry soldering joints on the PCB, loose connector joints can also cause these symptoms of shunting .

It is a power supply problem, you can get anew power supply or you can replace the electrolytic caps on the one in the set, that will fix your problem.

Turns on but doesn't do anything else. Screen doesn't come on. Can hear a clicking sounds like a turn signal sound.


looks like a( DLP) tv digital light proccessor . aka projection. most likely the bulb is burned out . if so cost is $65-125 bucks. aftermarket bulbs are available online but some dont work or burn out prematurely. if you decide to fix it or buy a new tv ,invest in a surge protector. it will save your tv from problems like this . good luck.

46in Vizio LCD HDTV distorted black picture when tv is turned on


Hi There are three things that can cause this problem. Your lcd screen, t-con board or the signal board. Most likelly in your case since you say it's only half the screen it's going to be your t-con board. You can try removing it and cleaning all the contacts and replacing it see if that helps. If that doesn't help then replace it. If that does not solve it then it's going to be your screen.

You can get parts at www.interliquidparts.com

I have a RCA 14"


Main control board is toast. Really not worth repairing unless it's in a specialty location. If it is, it's going to have to go to a repair center.

Watching and Suddenly turned black, but sound still worked.


Normal 0 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} It seems there is a loose connection between the board producing the picture and the screen; this is why this would happen. If turning the TV on and off makes no difference, try contact Phillips to see if they can talk you through a factory reset. If this does not work, the set may require service.

Visio LCD TV - Partial Picture blacked.


Hello! I have a 32" Vizio LCD...within 30 minutes of the tv being turned on, black lines start running through the bottom half of the screen and eventually blacking out the bottom half of the tv screen. It also doesn't have anything to do with the ratio as I have tried that. HELP!
