|
|
Hello everyone,
I was hoping I could receive some advice here on what is wrong with my television. I was given an old tv by a friend and the picture/color is not right on it. There seems to be too much red/orange and not enough green in the color. Also there is a blueish outline around everything and the picture is kinda fuzzy. It also seems too dark but that might be how that tv is made.
The television is a Sony Color Rear Video Projector and the model is one of the following:
KPR-46CX35
KPR-46EX35
Its an old tv its a '93 year model.
Thank you for any help. |

You have the typical convergence problem that almost every tube type rear projection set ever made has. There are two black IC's that start with STK on them that stand up against a metal heat sink that will need to be changed. It also sound like there may be a bad circuit protector , or feedback resistors that are blown in this set as well. These parts are soldered into place so you will need to first know how to solder on printed circuit boards. You will also need to get a service manual to trace and measure the voltages on the convergence IC's as well as do a convergence alighnment with the on screen service mode that this set has. If you have no experience with these things, play it safe and call in a pro to assist you with this repair. Good Luck and let us know what you found out about this repair job. |
