Trying to fix my 19-in Sanyo CRT TV

[Benyamin39]

Hi,

I finally found the problem with my TV. It was indeed the RGB modding I was preparing between the OSD and Jungle Chip. Although at that stage I had only tapped 3 to 4 open ended wires in different places, I may have shorted 2 adjacent circuit board lines on one of the soldering point. I soon as I removed all the wires, the TV was working fine again.

Because of the symptoms, I was misled that this was a 120V or HV side problem, and I didn't think the low voltage circuit would be able to create such issue. But thinking about it maybe I touch to some power of signal or Sync signal?

Thx for everyone's help and I learnt quite a bit of useful info about capacitors and how to test them. I am modding this TV now and the first results are encouraging.
