The above model TV started to flicker, losing red then reappearing. I don't think its the tube (guaranteed anyway), bt somewhere in the gun drive.
CAn someone point me at a website with the schematics?
I'm afraid my tv/analogue skills are rather weak as I'm a VHDL/FPGA designer. Any help welcome. (Also, my old 'scope burnt out, so diagnostics are difficult as well!).
TIA, Niv

so a bad connection
right
You only need a multimeter to track it down. Youve got 3 colour channels to compare too which makes things easier. I'd start at the tube cathode and work back, see where things start to line up between the 3 channels.

start by resoldering crt neck board etc. sounds like bad joint . may have led to the red resistor opening

Never hear of a Protron losing reds and reappearing, now do we?
