Dear firends and crt gurus,

I'm facing a problem with my BG808s. Once and a a while the lower corners of the image "flicker" like move and than stabilize, them after a while move again and so on.

Do you guys have any idea what could be the problem?

best regards

Check the 17 volt test point on the power supply to see if it is off. Info is on the main site. Can't link to it from my phone, sorry !

No, to 17 volts. See if by turning the pot a bit the flickering stops. 17.44 usually doesn't show issues on the screen, it's usually if you're out by more than 1 1/2 to 2 volts.

The strange is that the flikkering is not constante. Sometimes it happens not always. In one hour it happens once, more or less
