I would say there are power supply problems. It could be, but I am only 80% certain it to be a gassy electrolytic cap in the main power supply. When they short down they can cause these kinds of conditions.

Convergence is off


Starts up with black raster, then shuts down with LED blinking 4 times
This is the micro telling you that the auto grey-scaling procedure has failed. Change resistors R909, R913 & R922 (180k, 1%) on crt base PCB. You will probably find that all these have gone high
Standby only
Check R101 (4.7ohm), TR102 (C6180) and C126 (47uF, 16V)
Tv turns on automatically. Power supply works well, +5V present but seems that CPU (7700) does not (no standby mode), no remote or control on the front of the set
After replacing CPU (TMP47C434) and crystal 1770 (4.0MHz) both control worked intermittently. Replacing transistor 7674 (BC548) solved the problem
Will not work, standby (red) LED flashing
C604 in the 12V line is bad
Int going into standby
Replace C454 a 22nF smd, located near the Frame o/p ic.
