 |
|
The TV is a standard Daewoo
Before cap replace:
The first symptom I noticed was that the image was shrinked a bit by width and spreaded a bit by height. I could barely see the channel's logo.
After a week when I was switching it on there was a noise coming from the transformer, the image was bad, and there was no sound. After 2-3 minutes all these were gone and the tv was OK.
I opened it and a 100μF 160v cap was bulged, I replaced it with a new 100μF 450v and it was almost fixed.
Now when I switch it on the sound is OK and the image is clean bad totally dark. It lightens a little at the beginning but it takes 15 minutes to become normal...
I cant see something else in the circuit. What can it be?
Also I adjusted the buttons from the CRT neck circuit before cap replace and readjusted them after, but I had to set full lightness in order to have a normal image.

Be thankful we didn't recommend that you replace the sets Flux Capacitor. 
BTW, you'll have to do better:
