This may sound odd but try moving the remote further from the set. I have seen similar issue with my 42H81.

if this is a old unit the there is serious problem with the display.

check how many times the light blinks and get back to us.

You have blown one of the pecos fuses, probably the f850 or f852, you can test them with the power unpluggrd and with an ohm meter. Replace them with only the recommended amps fuse. Your set is going into standby, because of the blown fuse.

Good Day;

I would suspect the convergence IC's, to confirm this unplug the convergence yoke, all three. If TV comes on IC's are bad. Also, check the little green pico fuses. Good Luck, big IRISH.

I have the same issue with my toshiba 32" circa 2000. I am told that it is a burned out diode of some sort and it is a horrendous repair job.

You have a bad regulator IC or something in the seweep power supply is blow out. if you can read a schematic, i suggest you get one to troubleshoot the solid state circuits in this TV set. if you do not have any solid state repair experience or no electronic background, play it safe and call in a pro to assist you in the repair of this TV set. Good Luck.
