TV less than 3 months old.No picture but still got sound.Anyone any idea what fault might be.


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.

Vizio tv prolems. TV comes on normal for about 10 seconds (bright w/ colors) then picture dims with a hissing sound from the electronics. Anyone has an idea of a repair video to watch.


The hissing sound is over current from a shorted component. you best bet is to call around and see if anyone can repair it. Ask price first because you might be better off just buying a new one.

42'' lcd turns on no picture/menu


Your tv is being attacked by electrical surges which seem very violent and has already damaged some logic controls. Please invest in a AC filter which will protect your tv from such spikes....... but first you need to get your tv serviced from the electrical damaged it has already suffered.

My samsung TV won't show any picture/sound.


When the TV is on, need to check the back light is on(go back side & look into through)

If the back light is on -- need to exchange the Main Board
no back light -- exchange the Power Board --- 95%
exchange the LCD panel --- 5%(inverter)

No Picture, Indicator Light Green


If your TV is a year old or more, chances are that the power supply is starting to fail on your TV, causing all kinds of erratic behavior up to the point of not turning on anymore.
I service these power supplies since it does not look like there are many service parts available anymore. The only way to get this TV functional again is to repair the power supply to the component level.
