I spend all the weekend trying to fix this device. I take out ALL transistors and measure them with a transistor meter. All was good.
Then i did resistor measurement by took on leg in the air and i found that one of them (R3019 in PSU page) was 470K instead of 3K92 as you can see in picture.
I 've measured ALL the electrolytic capacitors too. Everyone was OK. Same with the diodes and big nf capacitors too.
I 've checked the pages and mark the components with yellow pen.
After that, i changed the faulty resistor, i did re-assembling all the PCB's, wires, etc.
Now when i switch on the device, i get very low intensity screen and no trace line at all.
The good part is that now the screen don't affected by small hitting the neck of the tube as did before repairing.
Today (i hope) i will do voltage measurements and post the results here.
