Hi
Ive just changed the 3 mosfets, 1 zd (5.6v), 1 ohm resistor on a z sus board for a 50ps3000.
The tv 50ps6000 as far as I can tell is basically the same as a 50ps3000 but with a different fascia.
When the tv turns on the screen is really white with the menus hazy accompanied by a high pitched buzz.
I have checked all the voltages and they seem to be alright apart from the vzb on the z sus which is 198 voltages. When I try to adjust the voltage turning in either direction clock or anti clock I still get 198 volts.
I thought the vzb should be around 105 volts?
Any help would be appreciated thanks in advance.
(btw I still get a pinky picture but what I have noticed as soon as I unplug it, as the voltage drops it goes normal for a second i.e black background with a normal menu displayed)
