I still have not resolved the problem with this set, which will not come on, it does try, but reverts back to standby. So far I have replaced both convergence IC's, frame IC & the line output tramsistor which blew for no apparent reason. I have had the PSU running on a dummy load and all voltages are OK. But when switched on the red LED flshes 4 times then stays on permanmently.(Back to standby) There is occasionally a chirp from the PSU as it tries to start. I am considering trying the LOPTX next, but would value any other suggestions as this is getting expensive.
Thanks in advance.
