Re: Sanyo DP46848 screen half dark
After resoldering the transformers and mosfets there is no change. Could it be the master or slave boards?

That's refection, I took the picture outside in the shade. I looked at it with a 4x magnifier and it looks good....Leave a comment:

I took the black plastic off the sides and there are master and slave inverters. I resoldered the power supply transformers and the mosfets and have yet put it back together to see if anything changed. I found the specs for the panel if that helps. Will post results when reassembled....Leave a comment:

That area is a little darker. I will resolder all points you made, I noticed there is a solder bridge near the one mosfet and a diode should I fix this too?...Leave a comment:

The power and signal cards are in a depression of the back cover, I took them out and hooked them up like the back cover isn't there...Leave a comment:

Sanyo DP46848 screen half dark
I have this TV that when I turn it on the left side of the screen is dark, then after about 10 to 20 minutes the left side (which I think are the backlights) will start to flicker and then will come on and stay on until I turn off the TV. Then if I turn it back on it does the same thing.
Any help would be appreciated
Thanks in advanced
