I have som problems with my Wells Gartner WG7487 there is no neck glow.
The large resistor (180R 25W) mounted at the upper left side gets very hot after 2-3 sec. (it gets so hot that i easy burn my fingers, then i turn the monitor off)
If i at the resistor where the read lead is mounted it get 150V and the other side at blue lead 15V
If i check the resistor i get 180 ohms reading...
I have changed the following components, but i still get no picture, but a verry hot resistor:
IC4 is changed the orginal where shorted (original where a STR30130, changed to STR3123)
HOT (d1398) is changed it where sorted
Flyback is changed
I have changed the following CAPS
C56 - tested high vloss - changed to 22uf 160V
C57 - tested open - changed to 47 uf 250V
C25 - tested open - changed to 1000uf 35V
C45 - tested ok but changed to 47uf 35v
C46 - tested ok but changed to 470uf 25V
C204 tested ok but changed to 4,7 uf 250V
C40 - tested ok but changed to 2200 uf 35V
C42 - tested ok but changed to 1000uf 35V
Diodes
D19-D21 tests out OK
If i measure volt at resistor R103 I have 151Volt, I have also tried to unsolder D10 but silll no neck glow.
Also tried another C57 Cap (47uf 250V) still same result
What am I missing?
