Question about Hitachi 43UWX10B 43" Rear Projection Television
A little background to the issue I have. I bought my Hitachi 42" projection back in 02' and it has worked great until today. I turned it on this morning and noticed that the picture has only pink and green colors now with a little bit of a double image on certain channels.
I've heard that this could be one of the circuit boards inside and perhaps the convergence circuit is bad. Could this be the problem ? If so, I would like to repair the board myself, but don't know which convergence IC's and/or components to change on the board. Any help will be greatly appreciated.
The convergence IC's you speak of are always mounted side by side and use the same #'s and are mounted on big metal heat sinks . Most start with STK392-??? . Also you may have bad resistors that are discolored and need changed as well . Some sets are protected by fuses but don't look like the typical glass fuses. They are pico fuse which could be green or yellow in color but look like resistors but do not have the color bands . Replacing the board could require a total convergence alignment. If you decide to take to a shop your avg. cost could be $250 to $300. If you do it yourself IC's and resistors or fuse would run around $50 to $70 bucks . Don't by the $9.95 IC's as they do not hold up as well . They should cost $20 to $25 apiece . Good luck
