2007 sorry too many years with PLASMA older. my thought too much to repair.
SOURCE: red light blinks 9 times on Panasonic TH-42PZ77U
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..

I had this problem in 2007 / 2008 here is what happened to me.
Jan 09, 2008 - I also have brought the unit to the authorized Panasonic repair facility and the problem is a failure in the P-board which is the power supply board. The P-board needs to be replaced. The repair will cost $475 plus tax. $250 is for labor. The unit was nop more than two months out of warranty. This does not speak well for Panasonic. I have been researching the problem and it looks like this has happened to many of the Panasonic plasma TVs.
Jun 14, 2008 - As an update to my problem with the failed P board. Contacted Panasonic Service and talked to a customer service representative. I told them how I have purchased many Panasonic products and how unhappy I was with the failure of the product. They proposed paying the labor cost of $250 and I would pay for the part. I just hope it does not happen again.

That's a fairly common indication that a component in the main power supply called an 'electrolytic capacitor' is fading away.
These are used as filters and in feedback paths in switched mode power supplies and one of the parts on which mfr.'s safe a nickel or two. If these parts are not rated for the type of service they perform (higher frequencies and ripple current) they chemically break down and lose value until they no longer can serve their purpose.
If you open the back of the set after allowing a number of hours (overnight is better) with the plug pulled, look for a smaller circuit board with larger than average parts. Some of these will be blocks (transformers and chokes) and it will have cylindrical 'cans' that are mounted 90 degrees to the board.
Look for a part number which may be on a sticker.
If you can find this, contact Panasonic service in your area and ask about repair or replacement cost of this board.
If either causes a faint heart, check on the site below to see if they happen to have this board on hand, it may save some money:

Subassemblies are normally plugged in and won't require soldering to replace.
