Hello merry christmas .
I have a runco DTV 852 projector, i can not find good vertical convergence for instance the vertical red line in the center is tilted to the right on the top of the picture and to the left at the booton .
i will appretiate if you can tell me if the failure lies withinin the vertical circuit board or stk392-220 modules. I do not have a plane or diagram of the vertical stage in order to check the voltage on those stages stk.
The leds of the vertical stage are lit glowing green.
the high voltage in the HV board is 1.285 volts.
thanks. Yareth from Venezuelan. yv5kgb@yahoo.es
