Question about Toshiba 50H82 50" Rear Projection Television
Since I'm having problems only with the veritcal adjustement of the red (the cross moves right & left but not up & down)
I decided to replace only one of ic's. Just to be sure, can someone point me to the right direction? do I nedd to change the Q751(RVBVGV) or the Q752 (RHBHGH).
I don't want to desolder/solder twice :)
Also, if someone can tell me how to test the part Q783 p/n: 23202037 it will be very helpfull :)
Q783 is a 2SJ512 (FET) with part number 23205037. These are not the easiest to test. If you suspect that it is bad, just replace it. It costs $2.48. I only have a listing for one convergence IC (STK-392-110), but if there are 2, replace the one labeled RVBVGV or just swap the two to see if the convergence shifts from vertical to horizontal.
Keep us posted.
