Question about Mitsubishi WS-55807 TV

1 Answer

Mitsu 55'' screen

Recently, when turning on my 6 year old WS-55807, the horizontal edges of the picture have begun to bow inward from the middle about 4 inches. Coloration is fuzzy throughout the screen. The condition clears itself - usually within 10 minutes of so, but I know it is a sign of a permanent condition to come. Is there anything I can do myself to fix this issue and avoid the inevitable?

    I have the same problem as described here, same model TV. It is very intermittent and it will clear itself, but I know it is preparing itself to probably have a permanent condition. Was this issue resolved by owner or by a service call? I am willing to fix it myself if it is fairly straight forward, but if complicated I'll consider a service call depending on the cost of repair.

The convergence ICs probably have a cracked solder joint on the foil side of the circuit board. Re-flowing the the solder would help. I will always replace the convergence ICs when doing this job. The labor remains the same and you will have to pay a few extra bucks for the parts. To fix this yourself, you will need to be able to identify the two convergence ICs (STK392-570), have a basic knowledge of electronics and be able to use a soldering iron.

This is a convergence rpoblem that is either bad connections on the pins of the convergence ICs or defective ICs. If you can solder and are comfortable working inside TVs where there are potentially dangerous high voltages, let me know and I'll provide additional details and instructions for fixing this yourself.

Tv bows

I have the same TV and just finished having my TV repaired for the same problem. I was unable to converge the colors even in the advanced convergence setup menu. The lines were bowing so far that adjustment was not possible. I had to replace the vertical and horizontal convergence controllers located on the main electronics panel. They require a lot of soldering and should be done by a professional. Unfortunately this is a common "maintenance" repair that happens every 5-7 years, depending on the usage, costing around $500.00 for in home repair. DO NOT USE YOUR TV IF THE CONVERGENCE IS BAD AS IT MY CAUSE THE POWER SUPPLY TO BLOW resulting in addition repair costs.

Good Day;

It sounds like your TV is experiencing a CONVERGENCE CIRCUIT failure. YES, it is worth repairing, it's a great TV. The cost will be from $450.00 to $650.00; call an Authorized Service Center and have them give you an estimate B4 repair. Good luck, big IRISH. PS: It's Not An Easy repair to do your self.

This mis probably a cold solder connection in the horizontal circuitry called the pincussion. Theres a couple of coils and resistors that overheat from time to time and the solder connections get loose. Not really for a handiman has this tv has hi vboltage inside even when turned off. Shouldnt cost an arm ans a leg to fix if the repair shop knows what they Are doing. Good Luck
