can anyone advise what could be the likely issue with the following monitors?
1: SC 1224 colour monitor, PSU OK as i tested and used it in another monitor
basically switch on monitor and green LED illuminates and you hear the static from the tube as though it's all starting up correctly
then! suddenly the green led goes off and the tube sounds like it's been switched off
then green LED back on and tube sounds like it's starting up again!
anyway this loop carries on and on so i switched it off
any ideas?
2: Philips CM 8833 MK I RGB colour scart type monitor
switched on, picture came on for a while then started to go dim, crackling sound from inside monitor and poof! picture gone!
swapped the psu and nothing so i guess it's something on the main PCB or LOPT or tube
again any ideas?
