The above model TV started to flicker, losing red then reappearing.
so a bad connection
I don't think its the tube (guaranteed anyway), bt somewhere in the
gun drive.
right
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
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.
