What model? Is it still under warranty? If so call the manufacturer they should honor the service if its still new.

I use to have a blue patch at the left bottom of the screen of my Sony WEGA TV. KDL 50WE 665. It,s been expanding fllowed by discoloration. Now today, the screen is black though the power is on. Any...


Difficult to address the black screen problem without diagnosis but the blue discoloration is definitely a bad optical engine. Sony extended warranty coverage for this until June of 2010 but no more. Cost of the part is around $900 so I wouldn't pursue any further repair.

I am starting to get a discoloration in the bottom left side of my screen. It is slowly making it's way up to the middle of the screen.


If it is a tube type TV, probably needs degaussing. The screen within the crt becomes magnetized or external magnets from speakers are causing a problem. Sometimes changing the direction or position the tv faces causes degauss problems. If moving nearby speakers changes the discoloration, then speakers are too close or TV needs degaussing. Some high-end Asian tvs have E-W adjustment in users menu to correct this problem.

If it is RPTV 3 tube crt TV, maybe a convergence problem.

If it is DLP or LCD rear projection, probably optical engine failure.

What model is TV. Is picture normal in BW with color turned off?

I replaced the lamp. now I have discoloration, Red on top and blue on the bottom


Your TV is an LCD rear projection type which requires a Mercury Vapor lamp. Mercury Vapor lamps emit UV light which is damaging to many materials. The discoloration you are seeing on the screen is the UV damage that has resulted over time to the LCD panels within the “Optical Block” (aka projector) of the TV. This discoloration has been creeping up on you for sometime, it just wasn’t as noticeable until you changed the lamp. Once you installed the new lamp, the UV light is bad at full force and the damage progresses at a quicker pace, due to the already weakened state of the LCD panels. Additionally, the picture is now brighter, exposing the damage for you to clearly see. The only fix for this problem is to replaced the Optical Block… an expensive repair. Although this is not good news, I hope this helps you understand the cause & solution and was of some assistance.

Its broken


RPTV Screen Repair

You have 3 options:

1. Visit local service shop with model number, he can check his TV graveyard for a possible replacement or order part then install. Problem usually solved. Screen from $200 to $500.

2. Locate model number, work on the part number, search the internet and order online. (includes the possibility of dealing with a wrong or damaged part that left the warehouse like "new")

Then get tools and start a TV dis-assembly project. Install screen (50-50 chance it faces the correct way). Usually they are easier to take apart than put back together.

3. Scrap TV if you can not get a used screen for $100

There is a discoloration on the sides of the tv. there is like a color of purple and green and makes the picture blurr looking- Guest


This is most likely because you have an unguarded speaker too close to the T.V. If you have a speaker close to the television, try moving it around a little to see if the discoloration goes away. If that doesn't work, you can try moving a large magnet around the edge of the screen to move the CRT guns back into place. Best of luck.

Projection TV problem


sounds like the vertical deflection is causing the CRTs to blank cause you still have sound and on screen displays. Try resoldering the vertical output IC see if that helps. If not you may need a new vertical output IC. Let me know if i can assist you further.

Sony 60" LCD projection TV has yellow screen discoloration


I would suggest to try to get this TV fix while still under warranty. Normally the manufacturers give one year.
In regards to the discoloration, there is not much you do but to let the Sony authorized repair center knows about it so they can fix it. Ask them if their work is guarantee as well for how long.
Good Luck.

Side shadows on picture


it sounds as if there are speakers to close to the tv or the built in speakers are not magnetically sheilded properly (maufacturer defect) if u have or have ever had speakers on the left and right side of your tv then the magnets in them will discolor and distort the screen. sometimes even long after the speakers have been moved away from the tv it will still look that way. you may try going to the library( or online )and looking in tv repair books on how to build a homade degauser unless your tv has that feature built into it in the menu somewhere like some computer monitors do. I had placed the front speaker of a 5.1 surround sound system on top my tv and it cuased that same problem, but i found out that by placing a small round magnet with a hole in the center on top of the tv (after removing the speaker for good) right where the discoloration was.. had to flip it one side or the other to get proper effect...it immediatly took away most of the discoloration and over time it disappeared. I hope this helps. Please email me at agclay777@comcast.net as to your conclusion in case it will help others. thanks, Adam
