It sounds like you have a power supply problem, this powers the inverter! Where you just replaced the inverter, we could assume it is good! Look for some bad caps (capacitors) on the power supply board. They will look bulged on the top an may be a little leaky (brownish stain). The power supply can fail on some output and be good on others. Was the back light inverter new? If all else fails, see if you can return the back light inverter and get another! I hope this is helpful!!

Hello my name is Helal. I have Sanyo 42" lcd TV have no picture but have sound. Screen black.


look for a bad fuse on the power supply board. If all are ok then look at the board that has a flat ribbon cable going to the bottom of the screen. This board usually is close to the center of the screen once you take the back off the TV. Parts can be gotten from shopjimmy's web site.

That sounds like a faulty LCD panel tab. The only true fix is to replace the screen. This usually isn't cost effective.

When tv turned on will get apicture for only a few seconds then screen goes black, but wil continue to have audio. Cannot pull up menu on tv either


Hello.The screen goes black means that the backlights of your LCD is not working.Maybe the problem is the power supply or the driver board of the backlights.They shutdown because there have a shorted parts on the circuit or power supply. Did you try to reset the power and turned on and get a picture or every time that you reset the power it will get a picture and the picture goes black?

  1. Try changing the input on the TV to see if the Blue screen goes away. Can you access the TV menu on the screen? If so, try running a channel scan until it is complete. Then check if the blue screen is still there.
  2. Disconnect any RCA cables, or other input cables from the back and see if you still have a blue screen.

I changed the capacitor on my polaroid lcd tv. It


Hello

Most likely when you disassembled the unit to replace the capacitors you unplugged the screens data cable. When you replugged this you probably didn't get it plugged in correctly or bent some pins.

Good luck
