Question about Proscan PS50670 50" Rear Projection Television

1 Answer

Picture problems I have a recent problem with my Proscan 50 inch. It was purchased 7 years ago and has spent the majority of its time up at my cottage, so has only seen limited use on weekends only. The picture is fine when the TV is first turned on, after about 5 mins, the picture starts to shake & becomes progressively more unstable. After a few minutes of this, the picture becomes completely unviewable. The screen has a big black band in the middle with distorted picture on top and on the bottom. Any help anyone can give me would be very appreciated.

Re: 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.

What replaces the Hitachi 50UX26B/27K from bout 20 to 25 years ago.

Currently these rear projection sets are no longer made by any major company and your only recourse would be to search for a used one--see them on Craigslist a lot and not very expensive.

Let me know if you have questions as I am here to help.

Sams club warranty problem

The bulbs aren't normally covered after the first year. Some extended warranty companies used to cover the bulbs after that, but now since the economy is bad... a lot of companies are trying to save money by not covering the lamps anymore. And the ones that did are handing the warranties over to other companies. You probably will just have to buy one yourself or you will just be chasing your tail.

White vertical lines in picture

It's not connections. On that particular unit I would suspect the Digital board, Samsung p/n# Bp94-02084a or the Dmd board. Have you ever noticed the picture freeze?
In any event, sounds as though you're going in the right direction having a tech test it out, it gets highly complicated...
Not sure why he replaced the lamp - but maybe he found it was about to expire.
Good luck!
