Question about Mitsubishi WS-65809 65" Rear Projection Television
You have several bad grounds in the convergence board. This TV will also need a new convergence IC. I believe it is a STK 393-110. It has poor grounds on its pins to the circuit board. I would suggest you replace it with a new one, it would be heart breaking to resolder the original IC and discover it is bad. It takes quite a while to pull this board out and replace. Be sure to check the 2 watt less than 10 watt resistors too. They can be bad. And I cannot tell you enough...there are also many,many bad grounds through out this convergence board. Please really examine this closely. Solder any and all ICs attached to heat sinks, power resistors, transistors, transformers etc. This TV is worth repairing. Thanks for asking and show a few hands of support!
