I have a shorted pic tube in a Toshiba 32" 32afx61 flat screen Thompson
tube.
Before I trash it how can I try to clear short? Shops want $100 bucks to
try 'with no promisses' of course. Id rather put taht money towards a
new
tv.
I know trying this is a last ditch effort. The tube is shot anyway. So
I
know I cant hurt it. Its only about 3 1/2 years old.
I already tried to isolate heater. The short is not to the heater.
The red gun is shorted I dont know the label of the other pins that are
shorted. It is NOT ...blue, green, heater, or G1. The 2 other pins that
are shorted to the red are connected to ground on the neck board.
Looking
at the tube from the back they are from
about 7 oclock to 2 oclock. The RK is in the middle and the other 2 are
are
at each end.
I tried tapping on neck. didnt help. I would like to try to burn it
clear
if that is the next thing to try. How can I do that?
Thanks
Roy
What are the other 2 pins labelled as? They may be alternates for
other CRT boards?

Im doing this from memory I could have missed a pin BUT I know the shorted
pins are the pins on the ends and the red K.
pins are numbered from 5 to 12 clockwise (not including the pin in the
'key')
none are labeled but I know what some are.
5- shorted to 8 & 12 --- this pin in connected to ground on neck board
6- green gun
7-
8- Red gun The SHORTED one
9- heater
10- heater
11- blue gun
12- shorted to 5&8 --- this pin in connected to ground on neck board
I'll confirm these pins tomorrow
