Hey everyone!
Got a brainer for you. Hantarex MTC900 with df04 deflection board, and 07 decoder board. Vertical deflection is near dead. Picture is vertically shrunk to a thin bar of about 5 inches in height. The vertical size -can- be adjusted, just not high enough... R110 is getting hot to the point of burnt smell. Deflection coil resistances seem to be in spec.
This is from a game I just bought for next to nothing a few weeks ago. Took the chassis out of the game, and it turns out mice chewed up the caps in there. Did a complete electrolytic cap kit, but some of the mylar caps are also chewed up badly. Can anyone point me to a parts list / schematic for the 04 deflection board? The video decoder board is okay.
After noting said damge started poking about tracing back the legs of the vertical amp, and found r116 to be at 1 ohms, which seems low (the colour code on the resistor is weird however, but it's supposed to start with a 9 or a 4 so... colours are faded but if all is right colour code should be green brown silver gold white).
If there's no exact arts list/schema available, I'd appreciate it if anyone checked the values of the following components on their chassis:
r116
c37
c42
c48
d28
d27
c47
Have replaced the vert output ic aswell (tda2653) but did not have the guts to fire it up once I found the out of spec resistor... would not like to fry the new ic... they aren'T too cheap...
Thanks for any help guys!
