Sounds like you're having vertical problems. I saw the vertical chip on this set go bad several times. Location is CN301. Sometimes you may see a big dent or even a hole in it. If that is the case, you need to replace it and check around it for any blown parts or loose solder joints. If you don't do that, the new chip will be destroyed. I have it in stock if you want it.

    Hi- I'm pretty sure this model also uses the same vertical output chip as the GB4308. Can you do it ? Frankly this is hard to say. You need to be able to work very carefully and to take the board out, or at least partially to get to the bottom of the main pcb to do some soldering / unsoldering. I don't know anything about your abilities. It is fairly easy to replace the chip but you have to be able to check for loose connections around it and also all the electrolytic capacitors in the vertical area. If you had done electronics work before, I'd say go for it. But if you never touched a soldering iron before, it could be tough for you - especially since any slip or wrong move can make things much worse. Sorry, but I'm trying to be honest with you. I can sell you the chip $12.99 shipped. Thanks.

There is some loose solder terminals at the vertical scan output section at printed circuit board. If you are handy in electronic circuit boards, loacate the vertical output section, resolder all the suspected solder terminals there. This must surely rectify the problem to your TV.

If the loss of picture is either on top half or bottom half of screen. there are y buffer boards that go from top to bottom on left side of screen when looking at back that control those sections. when there is loss of half of picture then buffer associated with that area would be at fault and would need to be replaced. when i see a degrading symptom such as loss of picture on top half or bottom half leading to no picture issue normally you would check heat syncs on y sustain board and if not heating up after a few minutes of being turned on would recommend replacing y main and both y upper and lower y buffer boards as they complete a circuit

Half a picture in black


Witch part of the screen you loose?if is the bottom or the top it could be a problem in the vertical IC circuit if is the left side or the right side is a problem on the horizontal deflection circuit(very rare),try taping on the set when it does it and see if the pix reacts ,if it does one way or the other you have loose conections and some resoldering need to be done.If you are familiar with tv circuitry you will have no problem.If you are not be safe and call for help.

Screen split with black bar through center, top of picture shows in bottom


It sounds as you desribe, the vertical output IC and or the b+ feed capacitor off the Hi voltage transformer feeding the vert. IC its required voltage. Not a really hard job to replace, but not for a handi person to do. This should be left to the professional, as there are no user serviceable parts inside this set and with the HI voltage and the safety issues its best to call somesone to assist you with this repair. Good Luck
