electrohome g07 Vertical collapse.
abispac:
So i was trying to use my electrohome g07 which i previously broke, so i took it to friend and he marked the parts that were bad in order for me to buy them and replace them , i did , now i just fired it up, and it has the infamous vertical collapse. Ive found serveral topics but most of them are way to long and most of them end up in not solving the vertical collapse. So i was wondering if theres some kind sould that would walk me trough and help me. I replaced a couple , if not most of the caps, and a small 3 leg black transistor, (not even sure if is called that) and the big round 2 leg transistor on the side, far away from the flyback, but on that one in particular , i have my doubts, as my friend marked for me, and when i was at the local supply store, i couldnt remember the numbers on the transistor so a quick google search gave me "toshiba 2sd870", so im wondering if is the correct part to use on that particular side. So if it is, what else should i look for, if is not, whats the correct part number? thanks in advance for any help.

I found the round transistor part number and hope ill get it today, ill post results later on.

Do you have a G07 manual? There should be no mystery as to which parts to use.

Yeah, i ---fouled up beyond all recognition--- on the one i bought, but after getting the manual now i know wich parts to buy, im just scared as several topics i found with the same problem, they never finish fix in it, i really would love to fix this monitor as it looks in good conditions, itas sitting on a warehouse for over 20 years or more. The chassis itself has a good condition. so i dont care if i have to change every componet , ill get it fix, but hope i dont have to change that many.

why are you replacing the 2sd870 for a vertical fault
if you have a vertical fault the most likely issue will be one the multiple resistors that fail in the vertical circuit or the vertical transistors
