Question about Sanyo DP46849 46 in. HDTV
Can't find a pattern to it, but our TV constantly get streaky plaid and stays that way for a long period of time? We've tried turning it off, switching inputs, etc. it will go plaid in the middle of a show or movie or sometimes as soon as we turn it on. Sometimes, the picture splits in the middle and is inverted? Guess we're going to buy a new TV soon

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!!

If your Tv is in warranty or you have a cover plan, you need to return the Tv for repair or replacement.Your Tv sounds like it has a power supply fault.
