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

1 Answer

I'm seeing red, literally, after buying this set for $300.

I bought this tv from a friend of a friend, just 1 week ago. It worked great when I first got it, so I thought I got a great deal!
Yeah, it's a little older, but I don't care about having the latest technology, I just want a tv that I can see from the other side of the room.
This morning when I turned it on, the screen started displaying everything in red, as if the red gun is the only one working. I'm hearing that everything for this tv is NLA, and this just makes the red really stand out now! I pulled the back panel, and all three guns are working, I held a peice of thick paper over the guns, one at a time, just to block the light beam. The Green and Blue guns are working, but I don't know how to adjust the individual rgb color level strength, or if the strength can even be adjusted. To make matters worse, I don't have a factory remote.
I don't know nothing about these older rear-projection tv's, but I am a competent computer builder, and I am skilled with electrical/circuit-board repairs.
If someone can point me in the right direction, for manuals, hardware, or just simple advice on this issue...
I would greatly appreciate it!

    Beautiful!!! Well, it would appear that there are some smarts behind that smart-alec! Cause I found the adjustments, played with them for a while, and now I'm definately happy! It's not 100% good-as-new color, but after 3 hours of fiddling, it's pretty darn close! Thank you so much... Now I get to move it back into my living room, and knock the adjustments all out of whack again :)~

    At least I'll know what I'm up against to fix it this time!

    Does anyone know where I can find a service/parts manual for this TV?

    I hear that the parts for these TV's are NLA, but apparently there are still quite a few of them still out there. If anyone could help, I'd gladly see what I can do to help out others who still have their sony KP-53's.

Through the front of the tv behind the speaker grill and behind the panel in front if the CRTs there will be a square object with 6 knobs you can turn. grab a flashlight and twist the RED SCREEN control to the left until the red is less prodominate. make sure you still have some red because then the picture will look purple. that adjsutment is called G2 or SCREEN control adjustment. try that be careful though because tooo far one way and the picture might start to blank.
make sure that you check all connections coming from your video sources also.

Sled4668w tv scans channals but always shows 0 found hooked upto dish network

This Orion TV made by Sansui was bought by me two weeks ago. It didn't last a week. The sound was terrible, picture was great, and it wouldn't hook up to soundbar without hearing a long delay in sound (A/V or Digital output tried two). I contacted their customer support twice, they were awesome. Told me this model has know issues and said to just bring it back. I found another TV for same price ($399) and same size (46) but it's LCD not LED, better picture and great sound! It is Insignia don't remember the model #. Bought at Best Buy (their house brand).

Watching dvd, great pictue and all of a sudden black out

7 Blinks is the failure of the SC/SU/SD PCB's (1 2 or 3 depending on how lucky/unlucky) you are.

Panasonic have a great warranty usually. Give them a ring, it has failed.

The flashing LED is the fault code.

Model tp50h95 old toshiba wont turn on

Hi, I am not a repair guy and know very little about tv's but I have the same TV set and experienced the same problems you're having about 2 weeks ago.

I found these articles helpful.

I decided I would try to repair it even though I didn't have any soldering experience and literally had to go buy a soldering iron. The parts costs me $26 including shipping and it took me about 4 hours to repair. I was so happy when I pressed the power button and my old friend came back to life. It is really simple to do and if you have experience you could probably finish in less than an hour. I hope this helps!

Hey guys I have a pretty interesting one for you. I researched all the convergence issues a few months ago, and new I needed to buy new IC's. I bought the C5AA00000203's from, which were...

Bad IC is my guess...

On anotehr note convergence is a very common failure on Projection TV sets.
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.

You can see some example photos and find a solution here...
