Chances are you should have checked some components related to that IC,namely an electrolytic capacitor.They tend to leak or short.That IC burned for a reason.

What did you use to check the caps?


retrace can also be caused by the master screen being set too high.

Absence of horizontal scan signal to the deflection yoke. Check all the connection to the deflection yoke. If found OK, the deflection yoke winding [horizontal] is open. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/

Cross lines ontop of screen my G21 M1 tv.. pls tell me how to solve it


The vertical output section of your TV has the fault. Replace all the electrolytic capacitors there, including smoothing capacitor to supply line to IC. Check for any loose solder termianls too. The lines you are seing across the screen, on it tope side, about 2 inches might be due to this fault, and are technically called [vertical retrace lines].

Several lines run across the top of the screen


Several lines acroos the screen at the top along with picture is a typical fault. You are seeing vertical retrace lines. Either the supply smoothing capacitor to the power supply given to vertical output Ic or vertical output capacitor connected to the vertical output pin of that Ic may faulty. Usually the supply smoothing capacitor seen faulty. It may be over 1500Mfd eletrolytic capacitor used there. It may get value reduced by 40 percent or so, this falult will occur. Please replace the two capacitors together and will get the result.

I have a panasonic tv with retrace lines at the topI


If you can locate the vertical IC you are nearby!. You will have to resoder the grounds on the vertical IC and any cap in the immediate area of this vertical IC is weak. I would replace them all as they will pull each other down. There may be four caps and the largest one, possibly a 25 volt 2200MF would be the only good cap. I dont have the specs on this set, but this will surely lead to a good repair!

Horizontal retrace lines at top of screen


Change 100uf 50-63volts capacitor next to the vertical output ic,if not solved check the vertical b+ filter on the 24volt line.If nothing else work try damping the vertical yoke with 2 300ohms resistors if in series or just one 220-330 ohm resistor if its parallel vertical yoke windings.
