I know this is an old thread, but I would like to post this information in the hope that someone will find it useful.
I just finished fixing this problem on my 1994 VS-6061... the problem is the PIP (Picture In Picture) board located on the Power Signal board.
The PIP board contains the numbers 530B552.
I bypassed the PIP board by following the directions I found at the following link:
"Plug in a 4.7ufd @ 35v filter cap (+)at pin 5,(-)at pin 11.
Plug in a .01ufd(any voltage) between pin 7 and 9.
Just plug the caps into the socket, where the PIP board was mounted (they don't need to be soldered). Just don't let the leads from the two capacitors touch, as they cross each other. The 0.01 cap is non-polarity, so either way it plugged is fine. Basically you will bypass y-signal through 4.7u, in pin 5, out pin 11, and bypass c-signal in pin 7, out pin 9 of the PIP socket.”
The bypass requires 2 capacitors: One 4.7ufd @ 35v and one Non-Polar 0.01ufd @ any voltage.
Remove the PIP board, then plug the two capacitors into the socket where the PIP board was mounted: plug the 4.7ufd capacitor with (+)at pin 5,(-)at pin 11 and plug in the non-polar .01ufd capacitor between pins 7 and pin 9.
If there is a ground wire (possibly brown) soldered to one of the tin cases on the PIP board, then you should connect this ground wire to the PIP socket either at pin 2, 4, 6, 8 or 10 which are grounds of the socket.
This PIP board was used in many Mitsubishi televisions and they were plagued with problems...This is why many of these older Mitsubishi televisions had similar problems…
