Question about Sanyo DP42848 LCD TV
The first thing I would check would be the electrolytic capacitors on the power supply board. If any of them are swollen or domed on top rather than flat, they will need to be replaced and that will fix your problem. I fix about 75% of them at the shop by replacing caps on power supply. A tech will probably charge around $100 if it is bad caps. It is a fairly easy job.

There is nothing wrong with the electrolytic capacitors on the power board as another posting suggests.
Not in this case.
What you need is a new main board or have yours repaired.
All Sanyo DP42840 units develop that problem over time.
Here's a link to a replacement board and there you can also find an option for repair service if you want that:
Hope this helps!
