Big circle in the middle of the screen of my Big Screen TV

I just received a big screen TV for free. when turned it on and adjusted the settings after cleaning it out, i found that there was a big circle in the middle of the screen. so i cleaned the RBG projection lenses, and the mirror that projects the image onto the TV. when that did not help i took the screen off. i noticed the screen was encoded with tons of tiny unseeable circles. i tried to clean them but it did not affect it. any sudgestions on how to clean it or fix it? and if not where i can get a new 52 Inch screen for it.

SOURCE: Cleaning mirrors and lenses on Sony big-screen projection TV

it's fairly easy to remove the screws on the back bottom portion of any rear-projector television. when the bottom part is removed, you will see both the mirror and the 3 lens. isopropyl alcohol or windex should do an efficient job. a soft lens rag can be found at any camera store. i'd spray the lens rag instead of the actual lens or mirror when doing this job.

There are light blue dots on the screen and now there is a big circle in the middle of the screen that is a different tint than the rest of the screen


Optical board is bad. Sony LCD Rear Projection TV Problems is Sony's link to all the issues of this TV. If you are the original owner of the set, contact Sony and climb the ladder if necessary. This has been a big problem for them and have resolved 3 class actions so far and have more headed their way. You could possibly get it repaired for free or a minimal charge. It's a 900.00 part! at cost... Hope this helps. if you need more info, post a comment and I will help further.

Bush tv has a circle on screen like looking thru a telescope


HELLO

Funnily enough I have been given a 21 inch standard Bush set with the same problem!

It's a DEGAUSSING fault. This means the deguss circuit in the TV is not operating as it should - probably a faulty positor. When you switch the TV on (NOT FROM STANDBY) the circuit that removes magnetism from the screen does not work correctly.

Switch it off, unplug the set from the mains for 30 minutes or so and try it again. If there is no change, contact a TV repair centre.

Make sure there are no hifi loudspeakers next to the TV or a radiator as this can have an effect too.

ALL THE BEST! (:-)

Tv rainbow in screen


The picture tube has become magnetized, possibly by someone getting a magnet to close to it. You can de-magnetize it using a strong magnet (cow magnet or similar). Place the magnet as close the the screen as possible without touching it to the screen. Starting at the middle of the screen and slowly (not too slow, about one full circle per second should do) move the magnet in a circular motion. With each full circle move the magent twards the outside (making a larger circle) as well as moving it farther away from the screen. Using a magnet will not harm the screen, so play with it and you'll soon get the feel and will see what you need to do.
Tv's have a circuit built in to 'Degauss' (demagnetize) the screen each time you turn it on, but this will only work if the set is 'Cold'. If the set is left off for 2 hours (to cool doen) and does not demagnetize when you turn it on the circuit is faulty.

Image has big yellow


Hi Zenmast

This is a burnt LCD that will need replacement. If the circle is yellow on a white screen , then it is your blue LCD that will need replacement.
