Question about Sony KP-53XBR45 53" Rear Projection Television

1 Answer

The red projector pulls away from the center and drops six inches

The television turns on and everything is normal for about five minutes, then the red starts to dance around and then drops about six inches down from the rest of the screen. I have tried to adjust it back up using the convergence control on the remote control but it does not move it. The red projector will stay like this for about an hour and a half, and then out of nowhere, it will pop back to normal. I cannot find a service manual online to help me figure this out, so if you could give me any type of help, I would appriciate it. Thanks!

The convergence output IC responsible for red probably has bad solder connections on it's pins. However, resoldering it will only be a temporary fix. To repair this set properly both of the convergence output IC's need to be replaced.

Magnetized needs degaussing


proceed with this steps and fix it. God bless you
Instructions
    • 1 Turn on your Sony Trinitron television.
    • 2 Flip the power switch on your degausser.

    • 3 Maneuver the degausser's coil so that it is a few inches away from the face of the screen. Draw the center of the degausser coil around the entire perimeter of the screen, and then return the degausser to the middle of the screen.
    • 4 Slowly back away from the Trintron's screen. This serves to decrease the degausser's impact on the CRT's magnetic field to zero. Continue backing away until you are about five feet away from the screen
    • 5 Flip the power switch on your degausser to turn it off. The CRT's magnetic field should return to its normal state and the picture quality of your Sony Trinitron should improve.

hi,
Possible problem is the faulty lamp cooling fan. Check the lamp cooling fan of your projector. if the RPM of fan is low then the lamp can get over heated. May be its has some problem.Do one thing, Remove the fan from the projector. In the fan there will be a specification sticker. Remove the sicker. now u can see a hole in the center. its the bearing part of the fan. put one drop of oil in it. u can use any type of lubricating oil. rotate the fan leafs with finger for some time. after that re-stick the spec sticker. insert the fan in the projector.

i have added a video how to oil the fan for make it easy for you.

ok

Six blinks indicates a faulty power supply. often caused by open thermistor located at under lamp assembly or beside it. Or a defective regulator on power supply section.. Check the thermistor and replace if found defective.. Or contact the nearest Sony service center at your area.

the lamp may have overheated. check it for bulges, black spots or fogging. replace it if you have any of those. since the lamp uses vaporized mercury, the only way to test it is in another projector. it may also be the colorwheel or the fans. if all of the fans are running and the colorwheel spins up, it may be the ballast. you could send it in to a sharp service center for repair. if you chose to, try av solutions in ny. they're really good. www.avsolutionsny.com

Center speaker channel


This sounds like a bad connection inside the receiver. A 5 minute fix with a soldering iron and about 30 minutes to get to it.
If you can solder you should be able to fix this yourself.
