Question about Panasonic TC-26LX60 26 in. LCD Television
For about the last 2 weeks our TV shuts off all by itself. We had Direct TV
installed about 2 months ago. Prior to that no problem. The picture is beautiful and sometimes the set plays for 2 or 3 hours, sometimes it shuts
off in 10 minutes. We unplug and replug and turn it back on and it's fine
until the next time. I have been thinking it might be an electrical problem
in our home and not the tv? Lights seem to be okay. Power surge plug
has been replaced and that is not the problem, although one day that went off as well. What is the problem??
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..

Alot of times capacitors on the power supply circuit board will go bad. They will bulge/dome or dry up which will cause this problem. Bad caps dont hold a charge, which is needed to maintain a voltage. The circuit board is two sided which makes replacing the caps difficult, and the board can be damaged and have to be replaced. Taking it to a repair shop may be cheeper and safer then doing it yourself. Having two-six caps replaced is a lot cheeper then a new board.

1. Reseating the connector P25 may solve the problem. If it does not.
2. Unplug the unit andd disconnect the connectors A5, A6, and A7. Apply power to the TV. If a White screen comes up and all voltages check normal, replace the P board.
3. If the TV stays on after isolating the SC board, then replace the SC board and the D board; it is likely that the fuse on the D board is blown.
