You have leaky capacitors in the vertical feedback loop which is not a major repair. Probably 100mfd/50v., in that range.( not $ )
I would venture a guess of $ 50 - 75.00 for the repair. Thats up to you.

Screen is blurred with horizontal lines when 1st turned on. Goes away after 15 mins. Also black cloud appears on screen....moves around then disappears after a few mins. What is going bad?


The fault should be with its supply voltage to video output section circuit. Check this voltage. Check the smoothing capacitor used there. The video output card stage, can be located at the back [neck] of the picture tube, will directly plugged on to it; and can be pulled back out gently. Take care. http://electronicshelponline.blogspot.com/ Check this link for more details. Pull up older posts.

Horizontal white lines 27A43.


You have some bad capacitors. They are located very near and next to your vertical IC. I would guess you would have to replace maybe four of these! Thanks for asking!

Horizontal blue line


The intermittent horizontal line is cause by a loose solder connection in the vertical amplifier IC.
The IC is mounted on a heatsink nearby or around the flyback transformer.
The way to fix this failure is to add fresh solder where you see some brown spots on the circuitry that were cause by components getting hot.
Good Luck.

Green screen with almost horizontal zigzag lines


Is good that you hit it and it reacts,very likely you have loose conections in different places but for the distorted picture you need to check the horizontal driver transformer and flyback after that is corrected you need to check the complete chassis for loose conections.Take your time.Good luck.

1.Are these lines only in the upper 1/3 rd portion of the screen?And is there a clear demarcation between this area and the lower portionb, where the image is perfect? 2.Or is thin Horizontal lines evenly spaced around an centimetre apart? If it is the first case, then there si a problem with your TVs SMPS. It is not generating the required regulated 110V required for the TVs functioning. If it is case 2, then there is a simple adjustment at the back - 'SCREEN'. This adjusts the Screen Grid Voltage, and by slightly lowering it, this problem will go away.
