Question about Westinghouse 26" LCD Flat-Panel HDTV

Open Question

Westinghouse sk-26h735s, no backlights or output from inverter board but the 24 volts going into it is good. Very faint picture (because the backlights are off) so I am sure the screen is good and I have tried a known good logic board with no improvement. The power supply voltages are all good except the 12v output is reading low at 11.7 or so and there is a slight ringing or buzz coming from the supply when the tv is off that gets a little quieter when the tv is turned on, also no sound. Is the low 12v causing my problem?

Take a strong light and put it up against the screen. Do you see a faint image? if yes, then your backlight has failed. Could be a lamp, inverter or power supply issue. Not for DIY'ers.

It's a bad capacitor on the power supply/backlight inverter board. Replace the board and you won't have any more problems.

Westinghouse sk-32h570d sound no picture

After ignition of the back light, a control voltage will come from the main board, to control the intensity of the back light. This is true to all LCD TVs. You should check, whether this control voltage [a variable voltage according to picture displayed on the screen]. If it is not present, make sure that the main board is faulty, as this voltage is generated at the main board and send to the back light inverter board' to control the brightness.

The TV turns on, has picture, then after about 15 seconds goes black but still has sound

The two most probable failures is the backlight for the display or the inverter that powers it, If the ends of the fluorescent backlight tube are exposed, check if the ends are black. If not, then the inverter is probably bad.
These are mounted on separate smaller boards that are pretty obviously connected to the backlight tubes.

No picture

It is either the 24vdc power supply is not working or the backlight inverter may have shorted circuits, those are the two areas you need to check.

Has sound,picture only comes on for a couple seconds at start up.

This is a Backlight Bulb or Inverter (power supply for backlight) failure.
If in warranty, take it to service
You can try to order an Inverter, or if needed you can get a replacement bulb (not easily available)
