Question about Sony KP-53S65 53" Rear Projection Television

2 Answers

Sony KP-53N77 Had trouble with the blue colors being half an inch off from red and green, shadowing over. Went into settings and found out the blue alignment grid at the top was curled under and the words for the settings were out of line.Took out print boards and checked solderings. Finally had to move the blue grid down about one two inches to straighten the top grid and words out. Then moved the red and green down to match. The colors are cool now but my screen is two inches low, but still reaches the top of the viewing screen. Do you think my blue tube is bad you can look inside the tube and the right top corner had a wave in it. Not sure what to do or just leave it alone?

    Thank you i'm an electrician and a repairman on restaruant and heat & air products, but i'm not sure i'll be tackling this one. Sounds like it could be bad. Got a great picture now, guess i should just ride it out. If nothing else i'll have an excuse to upgrade, any good ideas on a dependable product?

Well I personally like rear projection sets with tubes in them better than the new HD crap but Sony or Hitachi would be my choice if I had to buy one of the new format sets, good luck with it & Happy New Year, BMW Rider

Hi, you have a convergence problem, the IC`s and possibly a few precision resistors feeding the IC`s will have to be replaced, not an easy job if you haven`t done it before. If you are very proficient at solder work and can use a volt meter to check the resistors you can do the job but it isn`t easy for a lay-person, If you have more questions e-mail me back, good luck, BMW Rider

I have a sony kp-53n77 rear projection tv i cleaned the lenses but i still have alittle to much red how can i clean up the color


Older projection set:

Not knowing exactly what it looks like I suggest two things: first in the menu look for convergence to see if it is off adjustment wise--it can be adjusted in customer mode to see if that helps.

Also either turn color all the way off (Black and white) to see what color the screen is with no color--if somewhat red you will need to turn the red screen control down--I can tell you where and how.

If screen is too red, red will be the prominent background color with color off or on.

Another easy way to LOOK is go to an unused video input---should only see "Input 1" for example in green and rest of screen should be black and not red to any degree.

Let me know with a comment here what you find.

Sounds like a convergence issue. Call Sony for an ASC that can come out and give you an estimate. You are probably looking at $200-400 to do the repair.

Sony tv KP-61HS10 lenses wont align


This is common in those sets. One of your convergence IC's has stopped working and needs to be replaced. The convergence IC should be replaced and the convergence circuits realigned by someone with experience in Sony projection sets.
