Lines going across is a little vague but there is always the problem with the electrolytics (caps) around the vertical, be sure and get the one on the power supply too. Just change all you can find(usually 4-5). Thre are 2 convergence ic's if you didn't change them both, resolder the other one.
Then check the value on R519 for me.

Hello

red, green, and blue lines curve across the top of tv is cause by defective convergence STK IC or you have open resistor at convergence section. if you have defective RGB Color vertical ramp probably you have defective STK IC..

Replace your STK ICs and look for Bad capacitor by vertical IC 100uf 35v.

Just click below for convergence repair kit;

Double images and colors are blurry .Blue,red and yellow wave coming up from the bottom of the screen on the lower left and fuzzy images this is a symptom is for busted convergence IC,you must replaced this IC in order that will works better again.STK 392-xxx ICs and it's associated resistor,this resistor automatically change value,can caused truoble even though you change the ICs.If you bring this to a service center they cost you $600 to $700,but if you buy the repair kit you can save more,don't wory it is very easy because there is intallation guide including in the repair kit. Feel free to ask whatever the result... click the link for sample picture guide step by step installation;

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

51 big screen apex tv, convergence or verticle IC?


If the lines are thin and close together running horizontally, it may be the vertical driver, but that usually takes out the resistor and sometimes the diode in the B+ for the vert. Also you must replace the caps that caused the problem in the first place.

Three colored lines across the middle...


Sounds like the vertical control IC has gone out. Replace IC N301 (TDA8351) and check or replace R370 (1ohm), R371(33ohm), and R380(1ohm). This shouldn't affect the sound but once you get video you might figure out what is wrong with the sound (control setting). The TDA8351 crosses to NTE7156 and shouldn't run you more than $10.
