I have a Sony 53" KP-53HS10 high definition projection TV. I bought it back in June of 2000. Luckily I bought the extended warranty service plan on it.
In December of 2002, I had really fuzzy picture, with lines running across the screen. I had the best Buy warranty department come out and look at it. They determined it was the main processing unit for the video, also known as the A board. They said if I would have to pay for it, it would be about $300 for the part, and $300 for the labor.
Well, now I am having the same problem. I am almost sure when someone comes out to look at my TV, it is going to cost me over $600 to fix it, but probably more than $700.
So here is my question, I have talked to a couple of service places, and they say tat is a very rare problem. Has anybody else had to get a A-board replaced on their TV? Does anybody think this is consistent with Sony quality?
We use this TV a lot. It is probably on over 15 hours during the average day. Do you think the more a TV is on, the less it will last? 1 of the service places I talked to said the amount I had it on could affect the board, but really 2 times in just under 5 years the main unit goes out?
Should I just cut my losses and get a TV with the new DLP or LCD technology? I really don't want to spend $4000 on the TV I want right now, being that the other one cost me $3000.
Since this one has been problem/quality prone, do you think if I fixed this one, the same problem might come back in anoher 2 years? MAybe it is a bad power supply, or maybe we have bad wiring in our house? I do have the TV plugged into a surge protector... would faulty wiring play havoc on the TV circuits?
Thanks for any opinions.
