Question about Proscan PS50670 50" Rear Projection Television

1 Answer

Input feed problem

My mothr-in-law recently gave us her PS50670 and it was working fine. Just the other day, however, it started acting up. While watching cable and movies, such as DVDs through the coaxial input, the tv suddenly shows nothing but dark snow, kind of like white noise, only dark. If we shut it off for a while, it goes back to working OK for a couple hours, maximum. Is an input part going bad and can I fix it myself?

I would suggest using the AV inputs instead of the coaxial input. It looks like there might be a tuner intermittent failure but using the AV inputs bypasses the tuner.
Good Luck.

Sorry for the duplicate post, but somehow someone's not helpful solution got marked as solved, so I'm going to post again. I have a Sony Wega KP-51WS520. The problem is with the HDMI port. I have...


HDCP is causing the trouble You experience. Try using other video input connection for same set. If it works fine that way, the problem is that the rights protection (HDCP) is acting as "police" to prevent copying or reproduce unauthorized content. If only the HDMI is connected (disconnect all other inputs/outputs) on some sets, could be work fine.

SONY KP 51WS500 - Volume & Menu won't stay on


This would be weird for a sony but it sounds like the volume down button on the front of the set is stuck...very very uncommon for a sony. Try taking the bottom front cover off the set and unpluging the button assyembly then see if the remote works the set with it unpluged.

try cleaning The air filter in your set. It may be a thermal problem due to a clogged air filter.

TV Powers off


I think the lamp cover switch is acting backwards. Should quit when the door is off, and only work when the door is on. Look closely at the cover switch and see if it is messed up somehow.

Picture problems


Sounds like a problem in the main power regulator circuit, such as a bad capacitor or regulator IC or transisitor. There are no user serviceable parts inside these sets and every thing is soldered into place. I recomend that you call in a trained service tech to assist you with this repair.
