Will not converge


hello, the convergence ic's have gone bad in your tv . and sometimes they fail because of a 50 mfd @ 50v capacitor by each ic goes bad. if you have the skill at soldiering and desoldiering you may try repairing it yourself otherwise leave it to a qualified repairman. thanks .....techman...580-243-8025

Blue converence was intermitten now out on sides


If the IC's say have STK printed on them, then they are the convergence IC' s. should be three of them, replace all 3 , and the burned green coils, sometimes these burn as they supply the volts to the STK's. good luck, be safe..

I have a apex GB5108 tv, the picture has become a red yellow and blue horizontal line in the middle of the tv. is it fixable


Thats vertical deflection failure . Check the solder on the vertical output IC and the Yoke plugs. If that doesnt help you may need a new Vertical IC

Convergence IC's


I would bet its convergence ICs under 20 bucks at most electronic parts stores. Usually though the ICs take out a couple resistors with them when they go.
