whats up with my monitor

[jonny5]

i just tated my monitor in my cab like usual...didnt bump it or anything....popped it back in and do everything up

but when i start up the cab all i get is a blue line running vertical up the screen(what would be horizontal in yoko)

please tell me i did not just neck the tube...

ive looked it over and checked connections and i dont see anything wrong with it

only thing i can see is the neckboard seems a bit loose....but i also havent touched it before so i dont know if it was like that before.....im pretty sure the guy i bought it off swapped the chassis with another monitor.....

any ideas would be most appreciated

oh ya....its a stock nanao monitor in a new astro city

and no grant this is not my new monitor....this is a different one

you have lost vertical deflection
most likely your vertical yoke plug is off,next bad solder joint
follow the 2 sets wire from the yoke,one is red and blue and the other is white and yellow

or even more likely i forgot to reconnect the CP adjustment board.....

pheeeeeeeeewwww *cold sweat starts to dry*

yes a common mistake,if you had done that on certain chassis then you would blown the living **** outta the deflection and psu circuit i.e wg u5000
you got away with it this time

indeed....i didnt realize the CP adjustor was snagged so when tated the screen it pulled it out....all fine now
