Check the inverter, probably one of the inverter transfo's is bad. Al must measure the same for example 800 ohms, if there is one with an higher value that is the one to be replaced. Measure at the lamp side, not the power side.

Take a flashlight and shine it on the screen when you have sound, look very close, can you see a video image? If so the inverter is probably bad.
Let me know and I will assist further.

SOURCE: No picture sound only

your lcd tv is most likely not getting enough reception for the visual signal, try switching your tv back to analog signal (not digital) if you can by switching off av on remote, do you get your picture back, if yes thats your problem check your aerial, aerial leads and plugs, also do you have an aerial amplifier plugged into a power point, is it turned on to aplify signal.

SOURCE: the tv briefly powers up shows the memorex logo

The poroblem can either be the 12~18vdc power supply section is not supplying the power to the backlight inverter board or the inverter board went out, you need to check voltage on the power supply, also look to see if you see any caps with leaking/bulging top.

Try unplugging and replugging the TV to cause reboot. After reboot do a scan for digital channels.

Back - light problem. 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.

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.

Screens shows but then gos black


Confirm that all the input cables at the back are securely plugged at the rear of the screen and PC/output source and that the image source is switched on and displaying an image. This can be done by switching your PC on and waiting five mins. Then check that the power for the screen is on. If this does not work, then let me know
