It can be DC filters caps with leaking/bulging tops, or they have high ESR, bad transistors or IC or transformers in the backlight inverter circuits, bad lamps assemblies. Please read below and look at the pictures of bad caps, failed monitors, and troubleshooting guides.
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums

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.

LCD TV backlight goes off but still sound is present. Sometime it happen within few minutes and sometime take 30 minutes plus. Is that inverter Problem or CCFL? how I can rectify?


Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electronicshelponline.blogspot.com/ To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

26" LCT HDTV Backlight Problem


It can be that the inverter is not getting the 24vdc fromt he power supply module, check for that first, you can check it at either the power supply termninals or at the inverter board. Look to see if the power supply has any leaking/bulging top caps. Modules are easy to replace, fixing it down to component level is not so easy unless you have proper tools an electronics knowledges.

20" lg LCD backlight turns off after about 5 seconds of use.


First, check the power supply for the backlight. It's usually a 24 volt supply. Look for swollen caps. If that is ok, go to the inverter board and inspect for damage, ohm out the inverter transformers. Last is to test out the lamps seperately with an external inverter. If a lamp goes out this way, it is bad and causing the whole backlight to go out.

Tv immediately turns off


Four flashes indicates a problem with the backlight on the TV. It can be caused by the backlight inverter board (the power supply for the backlight) or by defective backlights in the panel It is USUALLY the backlight inverter board that is bad, but I have seen both components fail at various times. This set is fairly new and should still be withing the one year warranty, so you should contact Sony at 800-222-SONY to get it repaired. Be sure to rate this solution. Thanks!

Not really that tough. Sounds as though the backlight is shutting down, either from a power supply failure, or a failure of the backlight circuit itself. You can verify this by holding a flashlight to the screen in the area where the menu usually appears to see if it displayed on the LCD panel with no backlight. If you can faintly see the menu displayed, your backlight has shut down and the most likely cause is the backlight inverter board, followed by the power supply and the backlights themselves which are part of the LCD panel. If you found this information answered your questions, please be sure to rate it. Thanks!
