I have a convergence problem.

I have a Sony KP46WT500 Television Convergence problem. It bows and the alignment is way out. I replaced IC's and checked resistors and that didn't help the problem.

Did you check the power to the IC's ... normally when either one of the IC's burn out it takes out the power supply ..... make sure there is both a positive and a negative supply present there ... possibly + and - 28 volts or so .... if any of the voltages are missing ,check the 5 amp fuses that look like little green resistors on the power supply board ... that should solve your problem ....

I have an older model rca rear projection tv. The problem with the tv is that the picture bends into curve after about 5 minutes after it has been turned on. Please help.


Check the convergence IC's for cold solders, check for leaking capacitors in the area. Check the voltage regulator with a Variac.

Usually these sets just need the 2 big convergence IC's replaced with new ones. Clean all 3 picture tube lenses, mirror and screen. Get the original RCA remote that came with the set and MANUALLY align the convergence.

Rarely the bow on the bottom of the screen is not repairable.

Cannot adjust convergence on Mitsubishi RPTV


as long as there is no bowing in the picture and the color does not want to move then there is probably just a bad resistor on the convergence IC that controls the color alignment , thus the resistors would have to be tested to find the low valued resistor on the IC

Toshiba 40who8b convergeance problem


Good Day, harri1234;
Sounds like a convergence problem.
Convergence Output IC Failure
Corrective Action: Replace the defective Convergence Output IC Part Number 23905094 (STK392-110) using the revised “T” version IC Part Number 23135090 (STK392-110T). When Convergence Output failure is
detected, it’s recommended that both IC’s be changed to the “T” type IC
version.
Good Luck, Big Irish.

Sony kp-53s35 bowed picture on top and bottom


Good day, scotty1980;
Scotty, welcome to 2008. Hold onto your wallet, the has a convergence problem. Which means that the TV's convergence IC's are more than likely bad. The average cost to repair is about $450.00. Unless you are electronically friendly, I would call an authorized service dealer for repair.
Good luck, big IRISH. PS; Hope this was helpful.
