I believe your suspicions are correct. The video portion has failed in some way

Sanyo DP46142 TV comes on for approximately 30 seconds and then screen goes black. Power LED stays on.


Sounds like a backlight problem to me. If you input a signal to the HDMI or Composite input and then it goes black have you tried taking a flashlight to the screen to see if the picture is still there but just dark? That would indicate a backlight issue. That model appears to be an LED edge lit backlight, so if the picture is still there after going black your going to have to trace out the backlight circuit and see whats going on. Usually with LED backlighting if it comes on at all then the LED's are good, its just the driver supply thats failing to keep them on. Some TV's have a small separate board that provides the backlight control, but i suspect with this model its on the power supply board and not the motherboard. Have you checked that board? It could be bad caps on the power supply board, check the voltages to the backlighting when it lights up and then when it goes dark. It could just be some failed capacitors on the power supply causing that voltage rail to drop off.

Tip

Diagnosing a LCD blank screen problem.


Recently a 3 year old VIzio TV I bought started having problems. The set would turn on normally for a few seconds then the picture would go dark with everything else operating normally including sound. Remembering a similar laptop computer problem I diagnosed previously, I immediately suspected a defective TV screen backlight. To verify this in your own TV, get a very bright flashlight and with the TV operating in the failed blank screen mode, shine the flash light into the blank screen from various angles and distance (including touching the screen). If the LCD is still operating, you'll see a dim motion in the flashlight's reflection, thus proving it is indeed a failed backlight.

Vizio picture blank but lights up


you need to call a repair tech and have them check for blown capacitors in the power supply and the x & y sus (the circuits that light up your screen) for defective capacitors. they are very obvious to see-normally the top a a capacitor is flat, but in this case if bad they will be bowed out -rounded on the top.

No vidio only audio. when I disconnect one of the audio rca's( red ro white) i loose audio as well.....


The RED (Right Channel), and White (Left Channel) are for feeding the Sound to the TV, The Yellow is for coposite Video. Check that connection. Also look at the venting grill to see if you can see any white lights inside, if no light, then the backlight inverter board may have gone out or it is not getting the power from the main power supply.

LE40R74BD VOLUME OK BUT BLANK SCREEN


sounds like the backlight is out, can you see a picture when shining a flashlight on the screen. if yes you have either a bad inverter power supply or bad screen (panel).
both are serious , also could be just a few bad capacitors on the power supply, if you want you can do a visual of the power board caps will appear swolled on top and are easy to solder in cost about $1 EACH

No picture


Sounds like the backlight failed for whatever reason. Up close with a flashlight can you see a pic?? If so, Id's suspect a fuse in the backlight panel or the panel itself...
