sounds like the backlight is starting to fail.

we had a tech out. replaced main board at suggestion on phone diagnosis. NOPE. tech tested and the entire TV needs to be replaced. still waiting

This is a board level fix.
The part is about $10. + time to solder on the part
Capacitor C809 is failing.
390mfd @250V

just look at the owners manual of how to adjust the picture

When it goes black can you see a ghost image? It will be a normal tv picture but very faint black and white looking, you may have to get close and look at an angle to even see it. If so that means your backlight system is failing. If you don;t see an image then it is a problem with the power section of the board inside the tv.

Check if it is covered by warrenty and get a quote if it isn't. A 42 inch is new and big enough that it should still be worth repairing but it may cost you anywhere from $100 to $250 depending on the shop to fix.

Must return for waranty repair ur main video board backlight is dead,the main video board no good.

the x or y driver board is failing.best to have a servicer checked out

I am sorry Sir, the display panel is bad. If you purchased it new, it should under factory's warranty. Please call Proscan for a warranty repair.

If you use the connections for DVD you must use all of them.If you are using the standard yellow,white,and red connectors connect them to the connections listed as video and not the DVD titled connectors. But my advise is get an up converting DVD player and use a HDMI cable to get the best picture with out having to brake the bank buying a Blue Ray. I once connected a DVD player to my TV in the same fashion before finding out it only gives you a purplish black and white picture. Up converting DVD players can be bought around 30 dollars and up. A 6 ft HDMI cable will cost around 15 dollars. This way you will be getting the full effect and great picture your TV can produce.
