Hello ... Check the voltarege regulator, if the output of it is low it does not open completely ... The main filter also causes the same effect is bad, the most serious case is in the horizontal windings of the yoke.

Hello Friend. check the + b filter. It may be undervalued and check the polyester capacitors that were in series with the tsh. and check the other filters that are near the flayback and solve the flayback pins and other solder that you see cold or loose there from the flay resolves. Cheers
