Vertical sweep on NEC FE1250 Help!

Hi I have a NEC FE1250. The vertical sweep seems to be cutting out leaving me with a thin horazontal line in the center of the screen. This is intermittant. It can go out for a few seconds to minutes. It will then pop back to normail. Ive resoldered anything that looks like a cold solder joint on the main board. I didnt want to desolder the shield on the board connected to the CRT unless its necessary. ANY Help would be great! I to send this to a land fill when Im sure it can be fixed!

Unfortunately the LCD is going faulty.. one or more of the "Driver" transistors that operates the LCD elements RGB, have faulted ON.. perhaps this link may help fix it. Otherwise :(

Thin vertical green line

Could you please specify what type of screen this is? Or any other information that could help identify what type of screen it is?

A thin vertical line in a screen could be a faulty cable, faulty graphics card or even that the screen is faulty itself. But with more information on the screen the problem would become clearer.

Horizontal line, audio ok in LG flatron 21'' TV

It sounds like you have lost the vertical sweep circuits, it can be the Vertical out put IC is bad, Vertical yoke winding is bad, caps is bad. You will have to open it up, but you must be real careful since the picture tube can hold high voltage (24~30,000 Volts) for a long time after the monitor is unplugged, you will need to discharge the picture tube first before working on it. You may want to leave this to the pro.

Top of monitor screen looks like an accordian what does that mean?

If you mean that it looks like an accordion bellows, it is probably a defective filter capacitor in the power supply that runs the vertical deflection circuit. Get an estimate from a service firm for repair first and base that against a new flat-screen monitor purchase. Hope this helps!

A very thin vertical brun line in the middle

If it's a straight vertical or horizontal line always in the same place it's a panel issue which the average user even with repairing skills will not be able to reliably repair ,Sorry.

This indicates that your vertical sweep has failed and the auto protection circuit is shutting down the video so you do not permanently burn that line you see into the phosphor coating of the CRT.
At any rate, the vertical sweep circuits need repair before the unit will work again.
Good luck.
