Question about Proscan PS52690 52" Rear Projection Television

Open Question

Have a Proscan 52in Projection tv. It always dies about three months or so after moving from one house to another. It has always been the same problem and part. Ordered the part online and replaced it myself. It was the HV Block. Tv now powers up but the blue seems to be out of focus and blurring. Most notably seen around white abjects. Is there a focus that needs to be adjusted or is there something else that might be wrong. The general tips online say it can be focused with three pots marked screen voltage and focus but can't seem to find them. Can you help?

I have a proscan ps57660 rear projection tv, and the picture tube keeps jumping. its like the colors won't line up. every so often it will hold, but that is only when there is a full moon and martians...


TV repair guy is right. There are three separate tubes inside your tv (red, blue and green) that are set up to project perfectly on top of each other so that their pictures line up exactly. These tv's have shorter lives do to the fact that they are using the same technology as a conventional tv but they have seriously cranked the power up on these things. They run hotter and harder than any other tv out there. I recomend thinking fondly of the happy days that you had with this tv, then giving it a proper burial and upgrading to HD.

Is there a reset button for 52in rca hd ready rear projection tv?


Most likely there was one or more marginal connections on the main board and moving the set has completely opened those connections. If you can solder, try resoldering any connections on the boards that appear to be grainy or have rings. Update this with the results. That may resolve the problem. If not, we'll look further into the set for component failures.

Proscans are manufactured in conjunction with RCA what is the chassis number of your set? I can help you out if you can provide the chassis number. Should be located on the back cover of your set.
