We bought our tv from costco in 09. On 8/19 I turned it off and went to turn it on later a rd light was blinking at the switch. it was blinking twice and rest. repeating. Hubby talked to someone at store and had him unplug and hold down and count then plug in. took a bit but it came back on. Today it had been on about 3 hours I turned off, blinking starts back up. Only now it is blinking 10 times and pausing. This was rather sudden no other problems were present. Tv is used for many hours. The number is TH46PZ8OU. Don't see Z800u. made 12-08. serial # LF83370053 thank you

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..

The 7 blinks means that the SC scan drive board might need to be replace but only after checking the voltages from the power supply. If the voltages from the power supply are normal, then proceed to replace the SC scan board.

if you have a warranty let them check it out before opening the panels, it may void it.... may be an internal power short.
