[TechAssist] Re: Fwd: Diagram.

I appreciate your reply about my problem but realy I do not know if one 
section has something to do with the other one. Like sound section and 
vertical section. I'm going to tray to explain what the problem is.
This unite is a pain in the neck to work on it has main board, sound board, 
power supply board all separate.
The costumer said the problem start with the sound then the next day when 
they tray to power the power light come on and that is. 
I'm doing this job in the costumer home they live in a 6 floor and no 
elevator.
I found a black small fuse open I replace it and then the fuse blow again I 
change the H.out put and the regulator  before that happen then I found out 
the audio IC in the main board (surround sound) was blow so I change and 
install again the Black small fuse 5 amp. also change the vertical out put 
and check the filter around the vertical.
when I plug it on the high voltage come on but the picture look like one 
filter was not good in the vertical section  and in a few minutes the 
pictures was shrinking until it close complete. then I turn it off and turn 
back on and the same happen. them I move the vertical higth and the vertical 
line open up or the picture. but them I can not turn the TV off or change any 
control at all. when I put the vertical higth back where it was The TV 
control work perfect. But I still hear the sound not so good I hear the sound 
like when we has all the bass on no high sound. 
when I was checking all this I hear a spark sound  I turn the TV off and fun 
the IC that I has changed before the sound IC has a hole. I has spend all day 
there and at this time it was about 10.00 of the night I was tired of be seat 
on the floor so I left the unite to come back again with another IC. and I'll 
check all the filter around the sound section. 
And that is the story about this TV.
I hope you help me and send me the section that you think can help me.
Thank you and I'm sorry for the long Story.
                                            Jose.
