Question about Samsung HCN5527W 55" Rear Projection Television

Picture Bowed I have no idea what happened but all of a sudden the picture bows in the middle. I tried the convergence but nothing helped. The picture is clear in the middle, but thinner than usual then it expands to the outer edges but it is blurry. TIA

My sony tv model # KP-46WT510 the picture bows to the middle i tried fixing the convergence and it does nothing what else should i try

If the convergence feature did not fix the issue then you will need to install a convergence repair kit. Your model uses the Sony type 1 convergence repair kit which is available from www.tvrepairworld.com and includes the parts and the CD with instructions.

Picture bows in towards middle

YOU HAVE A ALIGNMENT PROBLEM, ON YOUR BOW OR PINCUSION, OR A BAD RESISTOR, THE COLORS NOT LINING UP COULD BE A CONVERGENCE PROBLEM. I ADVISE YOU TO LET A EXPERT TO THIS DUE TO THE HIGH VOLATE ON THE CRT(PICTURE TUBE)

Hitachi projection tv model 3 51gwx208

Do you mean that at the top of the picture, the red color has shifted downward, bowed towards the center? If that is what you see, one color suddenly bows toward the center on any side of the picture, then it means that one of your convergence IC's has burned out and needs to be replaced. It is a good idea to go ahead and replace both STK392-110 IC's with the newer improved STK392-150's. If you have never replaced convergence IC's and realigned the convergence circuits in a projection TV then allow a qualified tech to handle it for you.

Convergence amps problem.

If it works after a kick I'd say poor solder joints on the convergence amp leads
