Re: A straight line across the screen.
The problem may have been caused by the Vertical Filter Capacitors located in the immediate area of the deflection chip. If this is the case, and the chip you is bad. You need to check for a shorted capacitor before rechanging the chip again.". Please contact APEX for more info....The number is (800) 880-1227
I hope that helps

In the old days a thin line across the screen represented a fault with the frame circuitry; the frame oscillator or frame amplifier or the scan coils had ceased to work. No scan coils these days to fail but I reckon the fault is not user rectifiable and the services of an engineer will be needed.
It is during switch-on that components are often most highly stressed especially if the internal power supply is faulty or badly designed.
Few people would use a computer connected to mains electricity without a surge protector. It is taking a while for the idea to take root but almost everything is a computer these days and contains delicate cmos chips and circuitry which can be wiped out in an instant by an actual or an induced surge or a power transient and this especially applies to televisions and increasingly even to the humble radio set.
I advise everyone to fill their homes with surge protection off all types and not to use electronic apparatus without, even some power tools.
I needed a new telephone answering machine after every electrical storm until i started using surge protection and have not needed one since.
Vertical output IC has failed. It should be replaced. You haven't given the brand name and model number here. I assume that it is a Toshiba TV. If so, Visit this site for more details. Type in the site name "Electro-help" either Google or Yahoo search box [not
in the address bar of your browser], and click search. It is an electronic equipments service help
site. All details you want are
there. Note the position of
hyphen in between words in site name, when you type it in. The site will appear as it is in
web; subtitled as service help to electronic home entertainement equipments.

Well I belive you came to the right site but not the right section. Check for the list of different t.v combos until you find one that has the exact same t.v as the one you are trying to fix. You'll most likely have more of a chance of getting a more helpful answer there.
i'm no expert by any means; but I wonder if it could be as simple as the reflective screening on the inside comming loose. I have a 65" and I took it apart to clean it. The reflective screening looked to me like it could be a weak point. Just a thought.
