Question about Panasonic PT-53WX42 53" Rear Projection Television

1 Answer

Screen issue There is a small red dot on the screen approx 3/4 inch in size. Was told could be $150 to come a look, that the prob could only be dust on the projector element. This sounds like something fairly simple to fix...pretty good at dusting...clean freak. Any suggestions?

My mitsubishi 65in tv has a lot of small white dots on the screen what causes this?

projection tvs can display white dots from the dust that is on the reflector mirror your lamp shines the picture on before it is reflected onto the front screen of your tv, one must be very careful when cleaning this, may be worth a service man doing it for you

Sony wega 42 has red dot on screen.

Is the dot in just one location..if so does it ever change color at all. My first guess is something has gotten into the color display, like a small dust spec. . Or there is an issue with the front panel. If the unit is less than five years old they will look at it on site under warranty.

Blue section (corner) and blue dots

This set has no internal manual adjustments for color. The Tracking or B&W balance is accessed via the service menu. I don't suggest you attempt to adjust without instrumentation. the trouble with your set is not an adjustment. Most likely the Optics are at fault. This model has had issues with filters in the optics being destroyed over time by the lamp. The blue haze will get worse and continue to grow over the whole picture. The only option is to remove the Optics (light engine) and sent it out to be rebuilt.

Samsung HLN617W Screen Moved Up

Yes, you can repair it yourself. All you need is solder, solder wick, a capacitor checker rated at more than 1000uf and a screw driver.First, remove rear cover and locate vert. circuit. Check all 100uf capacitors around vertical output. Unsoldering one leg to remove from circuit so as to get a good reading. Replace leaky ones with equal value. Another possible cause for that is the convergence board. If you have colored shadows around the screen there is a small board up above main p.c.b. Simply replace it. Another thing to try is to access svc. menu and write down value of vert. hgt. Then change it back and forth to see if it is adjustable. this may be an easy, or difficult fix. Good luck, Russmann.

Red, purple and green dot

Its the light engine. Had a tehnician come and look at mine and was told it would have cost over $600 if I didnt have the warranty. Panasonic called 2 weeks later and told me that parts are no longer available for my model and are upgrading me to a 50 inch tv.(from 44 inch)

Blue dots

You have a bad blue LCD in the light engine. Replacement of the light engine is the only fix and it usually will continue to get worse over time

Green dot in middile of my screen

The green dot in the center sounds like a burn mark on one or more of the picture tubes inside the set, and the curved lines are telling me that you have a problem in the convergence circuits. The blue haze around everything white tells me you either have a lot of dust build up on the lens over the CRTs, or your picture tube(s) are very weak. If this set is over about 12 years old, I would replace it. I doubt if you will be able to get the green dot out of the picture without changing the tubes which would be VERY expensive.
