We turned on our Sony rear projection TV...and the convergence is a mess....we still get a piture although clearly the convergence is way off.....the front LED blink 4 times....the set is about 5yrs old and this is the third time it's needed repair.....I was hoping to get a service manual to decode what the 4 blinks mean and see if I could fix it myself......I've serviced other  TVs....but I'm certainly no pro....any help is appreciated.

These all sound like bad picture tubes or bad CRT driver boards. I wish I could help you but without any address where to send the manual, I just cannot assist you.

Hi Larry,

We had replaced ic chip for our Sony KP-43HT20 from reading this site.  It is much better but the blue line is still off.  We tried to adjust it but could not get it right.   I will like to fix it if possible.  Any suggestions?

Will you please send us the service manual?   My email is thkxyu8@yahoo.com.

 Thanks.

thkxyu and Mr. Chippy, I will send you both a copy of the Sony Service manual but I want you to look over a couple of things regarding your TV set before you try and tackle your convergence problems. One will explain to the most part, the problem you are having, and explain what needs to be done. The second thread I will be sending will explain the convergence procedure on the Sony TV sets. Good Luck to you both with your repairs.

You will need to look up the correct Sony part numbers and then go to partstore.com and enter the Sony part number. If you leave an e-mail, I will send you a service manual. Merry Christmas to you as well.

I had disconnected the leed for the screen control and operated unit with blue tube at low plate voltage. 4 hours later, unit was still operating so I shut it down and reconnected the screen control lead to the vairistor pack. It fixed the shutdown probleem and has been running for 10 days without a problem. I spent a few hours refocusing all the lenses and recalibrating the lower neck magnets due to a failed attempt by another to "find the problem". Thanks all for everything.

Larry:  My Sony KP-43HT20 projection TV was very good. I accidentally pushed Flash Focus button and it caused the convergence problem. I pushed Flash Focus button again many times. It could almost move the red and green colors together, but couldn’t move the blue color. The blue tube couldn’t project the parallel lines. The blue curves up and down on the left side of the screen and the pictures are blurred, I found this site is very helpful. Could you please advise me how to fix this convergence problem? Thanks.

Larry,

Hello there! I am new to the board and I wish I wasn't! The money we paid the t.v. repairman two months ago could have been saved! Let me give you a little history of my problems.

I own the Sony Rear Video Projector, Model # KP-51WS500. Some time ago, the red curved lines mentioned earlier in this thread, appeared on our screen. It was something that we could live with so we didn't spend the money to get it fixed at the time. Little did I know, until now, that it wouldn't have cost us a dime! Anyway, after awhile the television started flashing to red and would then shut itself off. So we would leave it off for a while and then turn it back on, problem fixed. Then, instead of flashing red, the picture would slowly fade to blue, with the sound working fine.

Once it started turning blue, we called in a repairman. He looked at it and told us that he had to order a transistor. He came back a week later and supposedly put in the new transistor. But I sat here watching him, and all he did was mess with the three little screw things in the front that adjusted the red lines from earlier. From what we could tell, the t.v. was fixed.

He did that repair on a Friday afternoon. That same night, we turned the television on for the first time and it flashed red immediately and then shut off. We turned it back on and all of the red color was gone. Now everything is green and blue. The picture is fine, except everyone looks like the Incredible Hulk! So the repairman came back and said that we needed a new red picture tube. That was the last we've seen him. That was two months ago, and everytime we call him he says that the tube is still on backorder. He doesn't answer our calls unless we call from a number that he doesn't recognize.

I am tired of dealing with this guy! And tired of giving him our money....$310 to date. Is there anywhere that we could order the picture tube from? Any help with this would be much appreciated! And just for s-n-g, could you please send my husband a copy of the manual? He's rather handy, so if this isn't the problem, then maybe it's something he could fix.  Thank you so much in advance!

Hi Laary,

 I am in the middle of repairing my Sony KP-43HT20.  I think it would be a great reference if you can send  me the Service Manual for Sony KP-43HT20.  If you got a minute, can you please send me the Service Manual to:

 dhuee@yahoo.com

Thanks in advanced,

David

Hi Larry,

 I took the D board off from my Sony KP-43HT20, but which one is the G board because I saw a lot of people are discussing on G board.

 Thanks,

David

I sent you the service manual but here I am attaching two very important how to do links that you should go over and learn before doing anything to your TV set. Good Luck.

Hi Larry,

I have been reading these posts & believe I am having a similar problem.  I have a 6-year old Sony KP-51WS500 wide screen projector that up until a few weeks ago, always performed flawlessly.

A few weeks ago, my TV developed a red shadow in the top left & bottom right corners.  These shadows were in a spiral pattern, rotating in a clockwise direction, getting better as you looked more toward the center of the screen.  The picture at the center of the screen is pretty much perfect.  A day or two after the initial problem, the problem cleared up on its own.

Two days ago, the problem returned & seems to be persisting. 

I've talked to a local repair shop regarding having them repair the TV.  They tell me that for them to repair it could cost anywhere from $250 to over $1,000, which leaves me in a quandry as to whether to have them repair it.

I've never done TV repair, but I am handy with a soldering iron, can follow directions and am very good mechanically.  My questions are three:

  1. Could this just be a convergence adjustment that the service manual would help me perform?
  2. If repairs need to be made, is this something I can handle with a little guidance from this Forum and/or the Serive Manual?
  3. Should I just scrap this TV & buy a newer model?

Please respond either via the forum or directly to my email: tpbachur@verizon.net

Thank you in advance for your guidance! Smile

Larry:

I apologize for taking this long to thank you for your advices because I was out of town. I’ve got the service manual and the links. It’s very helpful! I believe that I’ll need your guidance if the ICs need to be replaced. Thanks again.

Tom, If you are pretty handy, you should really have no problem trying the repair yourself. There are a couple of good links I will send you to help you make up your mind. If the TV set was mine, I would try to fix it first before throwing up my hands and buying a new one. Good Luck with your repair.

Larry,

Thanks for the information, I've read it over several times and do believe that this is something that I will be able to do myself.  Are you aware of a reputable internet site where I can purchase the "quality" IC's & replacement PICO fuses you reference?

Thank Again!

Tom

January 11, 2008 10:19 AM

I'll look at mine this evening & see which IC's I have...

Can you provide me guidance on checking the PICO fuses with a multimeter?  I do have one, but I'm unsure how to use it to test these fuses.

Thanks!

Tom
