Thanks
Any suggestions for what to look for? Voltage drops, voltage spikes?
I'm not an electrician so any guidance would be very helpful...

Can you please clarify? Which electrical supply are you referring to? The one inside the TV?...

Hi,
I've been living in the same apartment for about 5 years now, and moved into it with my old Samsung plasma TV (PS51F5500).
Ever since we've moved in, we would sometimes see strange power-cycling behavior. For example:

• TV would randomly turn off then back on.
• TV would turn off and the LED light would blink for a while (over a minute sometimes) until eventually it went back to a regular off state and could be turned on
• Sometimes it would require disconnecting the mains cord from the TV, waiting several minutes, then putting it back in and turning the TV back on. This had limited

Thanks for your reply.
Yeah, I have looked at the capacitors and they look fine from what I remember.
What is the purpose of trying this with the old power board? Do you suspect that the replacement board may be faulty?

Hi all,

I've had my Samsung PS51F5500 plasma tv for a decade or so. I bought it when it was one of the last units on sale, when plasmas were almost completely gone from the market, and it's been great and I was very happy with it.
About a couple of years ago it started sporadically turning off and back on again, every once in a while. I assumed it's due to voltage irregularities in the mains or something.
then, about a year ago it sometimes would turn off, the led would blink for a while, and I'd give it a rest, after which it would work again as usual.
finally,...

Hi there! I'm just a guy that likes to tinker and believes in repairing stuff when possible instead of throwing it away here for some guidance about resuscitating my beloved plasma TV
