Question about Hitachi 53UWX10B 53" Rear Projection Television
I recently found this forum and installed stk392-150s in place of my 110's. Then after installation, a few resistors were blown so i replaced as needed. Now I am in a predicament. I replaced RK 42 and RK 62 but they continue to blow. I might have the wrong size or something, but according to my notes RK 42 = 3.3ohms and RK62 = 2.2ohms (both 1W). I had the wrong size on the RK62 at first and put the right one in after and it blew as well. The 42 might have been wrong from the beginning but I dont have a 3.3ohm resistor to check that.
Why is the RK62 blowing when I start up the TV? Any ideas?
Oh and when I went to play with the convergence, its even worse. NOTHING will move now, as opposed to after I fixed the ICs I had full range with green, left and right with red, and nothing with blue. Now i have NOTHING. Any help?
Alot of people make the mistake of putting two STK392-150 Ics in the Hitachi , and most times it will not work unless you change all the convergence resistors.. If youre going to upgrade hitachi to anything other than the stock ICs, it is recomended by Hitachi to use the STK394-160 ICs but then you have to change the ratings on the resistors. You can get the upgrade kit for your hitachi at the following link.
