The set cannot be turned on or off. Nothing.

So, I Googled panasonic blinking power light and guess what! I am not alone. An example:

The only good news is that I bought the set from Crutchfield and they are going to come and get it (and that it happened right away so it is easily in warranty).

But this does seem to be a well known Panasonic problem.

Let the Buyer Beware!
Y board and buffers need to be replaced.

I'm still amazed to see people reporting problems after all this time.

I know for a while now, Panasonic has quit making Plasma sets all together if my reading and information is still up to date.

I've given periodic updates on my own set just to let people know how I'm doing, and after the initial repair in Warranty about 5 years ago now, my TC-P42U1 still functions perfectly. Even the display hasn't faded one bit, and still looks new. The TV is primarily used for movies and TV shows via a Roku3, or blu-ray player.

With that said, and after doing some research, I wonder if Plasma is still all that worth investing in, in 2015. Technology suggests that there are better alternatives now in the advance of LCD / LED technology and that plasma is a dated technology and is known as a whole for problems due to the high voltage requirements. I know from my own experience, both as a consumer and as a professional in the Video industry I can say the plasma set still gives a great and accurate picture, and response times, but so does my 2010 Sony bravia TV, and it seems even more so with newer TVs the gap isn't as large. I was just curious if plasma is going the way of the CRT now, and that's why I don't hear much about it anymore, even with forums like this one. This is the first update i got from this thread within 6 months to a year.

So I removed the *very tiny* capacitor off the MC201 board in October 2014 and did not replace it. The set is still running fine and it's been 5 months now. I *have* the replacement capacitor but don't think I can solder it in correctly due to the extremely tiny size (afraid I'll just end up bridging the two connection points) I did *not* touch the capacitor on MC301 as the "freeze test" showed the problem to be on MC201. I'm sure at some point the set will fail again and MC301 will have to be removed but I'll cross that bridge when we get to it
Update: I'm now at about the 8 month mark since removing the VERY TINY capacitor on the MC201 board, and the set continues to run fine. Still *no* replacement cap installed. And the set gets heavy usage - sometimes staying on for hours on end into the night and early morning hours. I'm thinking this capacitor is simply not necessary.

This is a common problem with Panasonic TVs, and a repair is very often a straight forward one - Y board may need to be replaced,simple troubleshooting need to be done first to make sure that it is the case,and buffer boards may need to be replaced at the same time;any trained tech should be able to diagnose it before replacement,but again- it is a common problem with Panasonic TVs.

Default Problems still persist now what???

Well my TC-P50S2 just crapped out about a week ago and I have been researching like crazy trying to find what the issue is. I have the 10 blinking lights and most are pointing me towards the SC/SD/SU board replacement. Great, but this isn't 2010 anymore and NOBODY has boards. Is it just time to throw in the towel and give up on ever getting parts. I love my plasma display and would love to keep the television, but where do people turn now Panasonic has zero support now for a TV that is barely 5 years old.

Anyone that could suggest anything would be great. I have seen shopjimmy and looked at the component fix and may try this as it looks like it's the ONLY option. Anyone ever completed this fix? Frustrated, but may just shotgun this thing and go with the LED/LCD 4K. I really don't want to spend another $1500 on another TV through.

Well just venting frustration as it looks like all Panasonics are going to end with this certain death.

Default No picture, steady standby led

I have a TH-50PZ800U and I have replaced the P(AC) Board, The SS and SC boards have green LEDs. My screen has a dim glow but you cannot turn the TV on, no picture, sound and no flashing LEDs. If I hold the power button down the TV goes off but when pressed again it goes into standby mode. Remote does nothing.
