Sanyo screen turns off and on.(DP32647)	Can't Post

Basically the screen turns off but the power LED remains green. It happens a few times randomly. The TV can stay in for days then it starts again. Sometimes before it turns off I hear a static noise and see some weird grayish looking image on my screen.The screen usually go back to normal after turning off but other times it stays black and I have to hit the power button a few times and plug/unplug it to get the screen back normal.I have some pics of the main board/power supply board.

I checked to make sure there weren't any loose connections or bad capacitors and it looks to be fine.

Here is a video of the problem.

The 1st thing I would do is to get RID of those "Football Stadium" sized pix...
Delete EVERY one of them..... Mad

...
NONE of us here have IMAX monitors !!!.. Shocked

..

Resize them to JPG or JPEG & repost them...
BEFORE you repost them , use the "Preview Post" button on the bottom of the reply box to see how they will look in the thread..

IF the are HUGE , resize them till they fit the thread better..
IF you don't , I suspect other techs will ignore them..

THANK you VERY much for your anticipated co-operation... Sly

...

BTW:...
I do not work on LCD , LED or Plasma TVs..

Have a nice day... Sly

Later...Ron.M... Cool
