I unplug it and turn it back on but will not work

Check or have a repair tech check connectors AP1 and AP2. Vibration rattles the power supply board (a crappy design, as the board is almost "floating") and causes the wires in the connectors to break, and may make intermittent contact. Heat may also cause intemittent contact. A very common flaw.

hello, panasonic plasmas have a safety shut down circut to protect the main panel when a short is present or internal circut panel is non functional some info i found in the service manual for 10th generation plasma
if your tv is still under warantee take advantage of the pany free service other wise it is a matter of exchanging the defective board then you will need electronic skills for this repair if you plan to do it yourself. it would be wise to have a skilled tech check it out and give you a estimate there are some techs that will come out and check it for free and give you a repair price.
here are some repair manual tips for blinking panasonic .. i didnt find 9 blinks on this manual i may be using a different manual but these are panasonic plasma blinking fault tips for 10th gen
becuase all models have different blinking codes you may need the model specific service manual
for 10th gen model some models 2008,2007,
8 Blinks SOS: Pin 91 of the MPU IC9003 monitors the status of the SS board. During normal operation, pin 8 of connector SS23 outputs a low to pin 91. If the SS board becomes defective, a high is provided to pin 91. As a result, the unit shuts down and the power LED blinks 8 times.
9 blinks panel config sos
10 Blinks SOS: The SUB5V and DT9V sources created on the A board are monitored by IC1100. If they are not present at pin 30 and 34, the MPU shuts down the unit. The power LED blinks 10 times.
10 Blinks SOS: The F_STB_15V of the P board, as well as the derived SUB5V and DT9V sources are monitored on the A board for excessive current. If a short circuit is developed in one of the supplied lines, pin 114 of IC1100 receives a high. The SUB5V and DT9V lines are also monitored for excessive voltage. When an over-voltage condition is detected, a high is also output to pin 114 of IC1100. The DT9V is provided to a DC/DC converter to create the BT30V for the tuner. If the BT30V becomes excessive, a high is output to pin 114 of IC1100. A high at pin 114 of IC1100 causes the unit to shutdown and the power LED to blink 10 times.
hope this helps..

the blinking power light is actually a diagnostic of a faulty part inside the set.
Here is the diagnostic info and which part you need to replace.
1 blink STV 5v sense DG Board
2 blinks 15v SOS D Board
3 blinks 3.3v SOS D Board
4 blinks Power SOS P Board
5 blinks 5v SOS D Board
6 blinks Driver SOS 1 SU / SD / SC Boards
(SC energy recovery circuit)
7 blinks Driver SOS 2 SU / SD / SS Boards
(SC floating voltage area)
8 blinks Driver SOS 3 SS Board
(SS energy recovery circuit)
9 blinks Panel Config. SOS
10 blinks Sub 5v SOS / Main 3v SOS DG Board
DTV 9v SOS / Tuner Power SOS
11 blinks Fan SOS PB Board
12 blinks Sound SOS H Board
13 blinks Communication error DG Board
with IC8001 (Pesks Lite 2)
if this set is still unedr warranty, please use the warranty to replace
the part. Else, have a professional install the new part for your
safety.
hope this helps.

Power board it dead,take the tv aparts.Check for Capacitors parts for puff up or burst open.Know how to solders?replaced these capacitors in the power board.Or replaced the whole power board.Tries Shopjimmy.com,Ebay.com.

With this symptom, it is impossible to tell what the exact "Cause" of this symptom is. The LED's do not tell us what is wrong, sometimes it may indicate the "Area" in your case it is the X board. BUT thats NOT where the "Fault is" thats just the part that is affected. These days unlike the "Old" analogue days it just isn't realistically possible to fix anything but the most basic of problems with todays sophisticated units. This is quite apart from the Safety aspect, any unit that can cause a firs or have an explosion, or both, is NOT to be treated lightly, and and the repairer, of the unit is legally responsible, another thing to think about. Also, one must have tools, a Multimeter, a soldering iron, a deslodering iron, an oscilloscope, a signal tracer, tools, and most important of all, a Service Manual, without which, there is no way to even begin to understand and fix it, and more importantly Program it, AFTER it has been fixed. As these days a TV, is a PC, a Tuner, and an HDTV Monitor, and more, all in one. in the "old" days TV"s were more, rudimentary, and built to last for 20 years, and a "Parts" supply was set aside. They usually used to fail for only a few reasons, and they while still difficult, were less difficult to repair. Electrical knowledge was transferable, and they could be and would respond to, This-is-the-symptom-This-us-the-Fix, But that no longer applies, as now, it can be a Fault on I squared Bus, or "Sensor" failure, or it simple may have "Crashed" just like a PC, It could be a Diode go bad, and that will stop the whole thing. You see, in the day, the sets were Very "Fault Tolerant" because they were Analouge, and a faulty, component, or more sometimes, the set would always diplay something usually, and when they didn't it was one of anly a few things, sure there are always the horrid ones, and there are pleanty of those, but all in all it was quite easy. But with Digital Electronics, it either goes, or it doesnt, there are usualy few half measures. I mean thats the definition of logic either going or not. So it can take very little to completely paralyse a set, and generally give the only sysmptom, it can, by not working, usually No picture, or the like. So you, see the list is endless almost for any given SYMPTOM, as that is what is being seen, not the cause, as I keep going on about. Also any fault, usually involves the Power Supply, it is either the cause, the cause of the damage, or it is damaged. or ALL of them. Then after you have done the electronic repairs, you then must program the set to work, and align, and set up in general, any one of those settings missed or done wrong, back to square one. So, it is nearly always my professional opinion that one should always get a "Quote" form the manufacturers recommended service center, I cannot stress how important that last point is. It is even worth the cost of shipping. you see an authorised service agent, will have trained staff, trained on their brand, also they have first hand access to parts, original parts. This will actually save you money and ensure you can actually get it back fixed. Of course asking for a "Quote" also gives on the option of repair or replace. Often my clients,do not go through with repair, unless it is moderate, but in some of the more costly jobs they see it, as do i, that a replacement, with a warranty, is a better option. As an aside here, one could then tear the TV down, and sell the Known Good bits. You'd be surprised who needs parts, i myself often must by from third party sources to effect a repair. So money could be recouped, somewhat,and help out someone else.
