R52wh76 screen goes black

if going black and sound remains it is either losing the High Voltage that fires the picture tubes for this model or is having the brightness blanked because of either a vertical deflection or power supply problem---things would have to be checked to see which kind of problem really exists.

I have a vs-60609 60"

Sounds like a Picture in Picture screen popping up, but if you do not have a signal from another tuner, it will be blank.

Try hitting the PIP button on your remote to see if it turns it off and on.
Plus go into the tv menu and find the PIP settings.

TV screen goes blank but power stays on

Sounds like the CRTs are going into protective blanking due to the vertical output ic needing to be resolderd. Try resoldering the vertical IC that may possibly fix the issue.

When the screen goes blank, hit any remote function that will show up on the screen-like volume bar. If the display is missing as well, then you have a tv problem. If the volume display is there when the tv picture is not, you may require a software upgrade.

Picture Fades

It isn't clear if the picture just loses color or the screen goes blank. If you are just losing color (picture goes to B/W) there is a problem in the color circuit and from your description it could easily be a bad solder connection on the board which decodes the color portion of the picture. If you are capable with a soldering iron and know TV HV safety, unplug the set, and remove the circuit boards and inspect (with a high powered magnifier)and resolder all suspect looking connections on the boards. You could also resolder all the connections which is more work but assures that solder joints are not the problem. If your problem is not solved at this point you are probably going to need a technician to look at it as it could be just about anything and probably would be beyond your expertise. Good luck and be safe.
