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!!

SOURCE: DP46849 has black screen with power light on.

It may be in safety shut down mode due to shorted circuits or power supply failure due to such thing as bad DC filter caps. You will need to do in-depth troubleshooting.

I have a Sanyo DP42841 I cannot adjust the screen size. When I try to adjust with PIX SHAPE I can get the big screen 4 but all the others are a box with gray bars on both sides. Interestingly enough


Roger, you might try this.. on some TV's it works. while it is unplugged push the power button on the TV and hold it in for 30 seconds or more. sometimes this Resets the tv back to Default setting. Hope this helps besides even if it doesn't work you haven't hurt anything or lost anything..

No picture on screen


Is the TV under warranty? If it is don't muck around, contact them straight away as you have a electronic problem with your screen.
Before that make sure the yellow chord is in the visual port and red and white into sound. 2) If thats all good try an experiment, as you know the sound is good, use one of the sound cables to replace the yellow. Is there a picture now? If so replace chord, if not make contact to exchange for warranty.
