No Vertical deflection
working on kortek2914f chassis here is where i am at i recapped the chassis reflowed solder everywhere it was needed and replaced the ver ic 201. it wasnt working at all when i got it. so now i have neck glow and high voltage but no pic but when i turn up the screen on the flyback all the way i get a horizonal line in the center of the screen but not all the way across any advice or pointers would be great
A horizontal line means no vertical deflection
so the problems in the vertical circuit.
You replace the ic that goes bad in that model.
and caps in the vertical circuit.
now you need to make sure it has voltage to it..
R206 and r207 need to be check low ohm resistor
these resistor supply voltage to the ic they dont normally
burn up on thier own. The first place to check on this chassis
is the verticcal circuit if the resistors are bad.
then order the resistor and ic with capkit if not done yet.
Its important to use the correct size ohm's and wattage
one reason is space it can not touch the vertical heatsink
it has supply voltage on it. dont worry why not all the way across issue.
just restore the vertical circuit. If you use the wrong ohms it wil effect the size linearity
and add to your notes that the schematic is at suzohapp parts dealer
home page under product support which where you look for details like schematic and parts list for part value's.good Luck!
