Trying to fix my 19-in Sanyo CRT TV

1) post just the schematic.
2) check for cold solder joints especially the horz out & flyback area.
3) look for an electrolytic cap associated with the ON/OFF relay coil
power supply.

Odds are it should be an easy fix but take your time & stay on track.

Hi Zeno and thanks for all the responses posted on this thread so far. I have hope to fix it.

First, the TV is Sanyo DS19204, I missed one digit there.

1) Here-below is the schematic

2)
The first time I checked the capacitors, I checked all of them on the 120V sections and then everywhere else. I used my multimeter in ohmeter mode to detect a change in resistance. All electrolytic capacitors were ok but I will double check. I will look for the flyback area. For the ON/OFF relay coil power supply I can't locate it on the PCB at the moment. There is a power regulator (IC601), would that be what I am looking for?

reopening the TV now.
