Question about Televison & Video

1 Answer

I have a 50 inch Pro Scan Projection TV that was bought in 1995. I was just watching tv yesterday, everything was fine. All of a sudden when I changed the channel the picture became blurry like it had a slight double picture and the picture also took on the appearance as if I was watching the tv through a drinking glass, kind of concave in appearance. I immediately thought it had something to do with my Verizon Fios since I have had problems with just this tv (which has the main verizon dvr box) and so I do what I normally do, pulled all the plugs, etcetera. When that didn't work, I called Verizon. After about 50 minutes with them on the phone while they manipulated my box through satellite (they also had me put in a dvd and the picture did not clear up)nothing changed and they told me something was wrong with my tv. I am still not 100% positive this is the case because of an earlier incident when actual verizon techs came to my house and had me convinced my tv was bad, and it turned out to be the Fios. However, I am starting to think it may be the tv. What do you think it could be, especially when it happened so quickly with no preview of what was about to happen? P.S. There was no storms or anything else going on other than I described. I literally just went to click on another channel and, presto, picture shot!

If this set is a PTK169 chassis, you could have bad tuning capacitors in the horizontal for the Horizontal yoke return and pincushion circuit. I would suggest that only a professional diagnose and repair it due to the circuit it is.
Hope this helps,

The projection bulb came on,but didn't stay on mean the bulb have problems,dosen't mean projection bulb it still good.First must replace a new projection bulb to make sure for the elimation for the projection bulb is the problems.These DLP tvs require new projection bulb every 1 1/2 or 2 years by watching the tv like 4 or 5 hours daily.So there no lost there for trying a new projection bulb alway can save it for later use.The secound could be the board that call the Ballast board have problems too.The Ballast board only job it is to ignite to the projection bulb and make it work.Replace the Ballast board too,if the tv new projection bulb react the same way.

I turned the set on and everything was fine, then the screen went black and mullti-colored horizontal (arched) lines were flashing across the screen. The next day I turned the set on and everything was fine for about 5 minutes then the problem reoccures again. Haven't looked for solutions till now.
