Okay so I probed it with my scope and here are the results,was scoping with the disconnected (G2) feed resistor to the PL504 and I heard the oscillator just a bit,not as loud as If I connected the g2 feed resistor back ...
I also measured the PL504 cathode current at first when it starts up the current is between 190-210 mA then it goes to 220-250 mA and isn't still,it jumps a bit down and up and down,when it reaches nearly 260 mA then red plating starts ...The horizontal frequency coil has a affect on the current but the current just keeps jumping around,the EHT ,both deflection seem to be stable and working fine ...
Voltages : some of them are off ... The g2 feed resistor to PL504 connected !
PL504
1. -37V
2. -36V
5. 54mV
6. 160V
7. 160V
8. 0.2V
9. 17mV
PCF802
1. 213V
2. -0.8V
3. 97V
6. 150V
7. 11.22V
8. 13V
9. 8.5V
PCL805
1. 300V
2. 230V
3. 250V
6. 258V
7. 250V
8. 32V
9. 11.6V
What would cause the cathode current to jump around like that and not be stable ?
The 500K potentiometer in pic was burnt a bit ,but when I tested it tested GOOD ..
Then I replaced the VDR resistor and it seems to be fine now ...
This TV is beginning to be a real pain in the ass ...
