This damage is caused by damage to the resistor 525 with a value of 137k ohms, the resistor at the B + abl.
The symptoms that we can see the result of damage to the resistors 525 are:
- Picture looked dim.
- If exposed images directly image the light horizontal lines (such as damage to the vertical circuit.
- Secreen opened a line drawing, secreen diminished dim picture but normal.
If you see problems like the above then the only solution to quickly replace the R525, guaranteed to be OK ....
