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... i have a sanyo DP42848 i turn it on and 3 sec the screen goes blank and the sound still on..i think it might be the black light converter board..can you point me in the right direction...

You are right, in most of the case It is the back lights inverter board.

If this TV uses a LG display panel, it uses a single, or double inverter board, you may check out that if there is any PUP-UP electrolytic capacitors, if you do change them all.

If it is not a LG panel, you have to change the inverter board.

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.

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.

Sanyo DP26649 screen blacks out and sound becomes loud static

Most likely you will need to get a diagnoses performed on the set. Your problem could be with either the main board or power supply board. The million dollar question is do you repair or replace? With parts and labor to repair this set, you could come out cheaper replacing it.

My Sanyo tv screen goes black for a few seconds but I still have sound. Happens normally when my central air clicks on even though I have my tv on a surge protector.

is this an lcd tv? if yes the cause is loose connection in the power inverter board connector for screen back light.

Tv screen goes black ater 10 seconds

there could be several things causing this, most often it's a defective inverter, or a bad CCFL lamp. You could also have a problem with 24vdc output from the power supply, or "backlight on circuit from the main board. Get a proper diagnoses.
