TV22 lines across screen is there a cure ??
I have a TV22 I restored a couple of months ago since it's been up and running I have very thin light lines running diagonally up roughly the top half of the picture on brighter images is this a fault I don't remember my last one doing it.

diagonal lines can be interference from switch mode supplies, radiated maybe or converter power supply ?

This sounds like flyback lines which is normal if the brightness is turned up to high.

Some information on removing flyback lines on TV22, with a forum search you may find more examples.
