help how to spark CTV RGB gun

<< < (2/2)

BC109:
I was very skeptical about this method when I heard it, but I have to say it works 90% of the time.
Not for the faint hearted though  :bo:

theo laird:
Have a diagram of a device somewhere from the late 70's it used parts from an old Philips G8
Crt 6volt Transformer G8
1n4007 diode
240volt 60-100watt lamp, wattage depending how fierce you need to be.
CRT base for tube type, if not flying leads have to be used, (not advised for safety.)
The G8 RGB gun switches were also used to tickle each cathode as needed.

If I can't find the diagram I will attempt to draw from memory as soon as possible.

This device kept crts going at least an extra 2 years before crt replacement was considered. A great saving with a 1k TV rental business 70's and 80's.

P.R.Gore:
Rodneysccx, what BC109 has explained is a wonderful method! Recently I tried it for removing green cathode with filament. Thanks BC109. What he means is 1) first find out which pin is shorted with whom. 2) isolate this pin from circuit track 3) connect all other crt pins to chassis ground by isolating them also from rest circuit 4) if shorted pin is focus then connect final anode to it 5) if shorted pin is other i.e. cathode, grid (control or screen) then connect focus wire from FBT to it. Start set momentarily to produce spark. The spark then removes short. While doing this risk is always there!!

BC109:
Remove CRT PCB from tube.
I use solder wick and weave it around all pins to be earthed, connect to clip lead then to earth (aquadag).
Use another clip lead to connect to faulty pin, then strike HT to end of lead twice.
I see a lot of newish LG's with shorts, and this clears about 90%. Nothing to loose.

BUT PLEASE NOTE THIS IS DANGEROUS IF YOU DONT KNOW ABOUT TV HIGH VOLTAGE!!!!
Is your life worth a TV?

If the above needs any more explaining DONT DO IT!
