There about $300-$500 and it's not worth fixing if it is the tube - if you replace only one tube it will be too bright relative to the other two and you'll have to under or over compensate to get a good picture depending how worn the other two tubes are.

I have a 50 inch Sony with the blue screen problem. I have looked for replacement parts but cannot tell exactly what I need. Any suggestions?


I recommend you talk to Sony directly and they may offer you an exchange with latest model with a great great discount. Mine is on the way for delivery with the same 'blue screen" problem. Dont bother looking for part replacement which will cost more than a brand new replacement from Sony. Good luck.

I have a sony 50 in rear projection. 9 years old


Sounds like the CRT tubes are going out which is fairly common on Sony. Inside the back of the TV there are 6 knobs - 2 for each color...one is for focus - dont touch - the other for brightness...turn down the brightness just a hair untill the lines go away.

BLUE TINT ON SCREEN ALL THE TIME, COLOR ADJUSTMENTS FINE


Sounds like a bad blue CRT (picture tube) ITs expensive and difficult to replace. CAll a Sony service center for an estimate. but expect to spend $500-700 to replace it.

You have a bad blue picture tube. If you replace it the red and green will be weak and probably go sooner than you think. Everytime I had to replace a tube in a sony projo tv i had to replace all 3 picture tubes at the same time. It's very expensive if you don't have any type of warranty coverage.

Sony Grand Wega KDF-E050A10


Authorized sony repair center told me the problem was the Q Box. Ever heard of this? Part runs about 300 bucks. TV is out of warrenty as it is 2 years old. Do you think it is worth it to fight sony and get them to replace the part or just fix the TV?

Part Number is A1167541A, service rep called it a Q Box in the diag, however the web says its the b block assmy.

read this if you think it's the same problem
