Sony KV32TS35 update- need schematic



Jan 1, 1970
Hi group. Here is an update as I said I would post. I replaced the
stereo decoder as suggested and this fixed the distorted audio. Here's
the history: Plugged the set in to see what the probelm was - friend
said picture and sound went out. Had a perfect picture, distorted
sound, then after a few minutes the raster went black, still had sound.
I turned up the screen voltage slightly and saw a horizontal red line.
Replaced the vertical IC but no change. I resoldered the jungle IC
also, and checked the deflection coil - 3.5ohms. Should I be looking
for a high ESR cap? I would signal trace the vertical but I don't have
the schematic. Which pin of the jungle IC should I start from? I am
fairly new to repair, so without the schematic I am shooting in the
dark. I was hoping someone could give me some tips, since I would
rather not have to purchase the schematic. Web search came up empty on
free schematic. Thanks again group, and I will continue posting

Do you have supplies from the FBT secondary to the vertical IC? If not look
for an open resistor.

When working without the schematic, look for a datasheet on the ICs for pin
definitions. First, check the obvious like supplies and bad solder joints.

Thanks Leonard. I do have voltages on the vertical IC, just not sure
what's normal. I will look up the pinout on the Jungle IC and trace
from there. Will post a follow up.

Hi there. I'm trying to fix my KV-32TS35 as well and would also lik
a copy of the schematic

If it is any help, I found a schematic of a KV-27TS35, which might b
very close

Is the horizontal line in the center of the screen or at the top?

Schematic on it's way to you.
