hello, you have a either your su, sd or sc boards fualty and it is a driver sos1 thats what the manual reads the best thing to do if your not electronically inclined or able to fix it is to get a service manual and make sure it is for your specific model and size you will find what the 7 blink codes mean, on my side i have a 42 in pana the service manual for this set and your is similar so since it is not the same model i cant tell you exactly what the truoble is but your best bet is to find a service manual find the 7 blink fualt then without getting ripped off you will know what the service man needs to do if you dont know or cant replace the parts yourself that is besides having to download firmware from your computer to a sd card and update your set but you need to solve the blinking code first it may solve the entire issue. the tv should come on when you resolve the blink codes or replace the fualty board or boards

This sounds like the panel itself is cracked. If this is the case, the set wil not completely power up as youi have seen. The panel can not be repaired as such, it must be replaced. I can rpovide you with the part number and cost if you can post the model number. Be aware however, that the cost of the panel may come close to the cost of a replacement set.

Testimonial: "Model # TH-42PX80U"
Panasonic said "A" board,
A board SOS Detect (Explanation)
10 Blinks SOS: The voltage regulators IC5400 and IC5401 in the A board generate SUB9V and SUB5V. The 9V and 5V from these ICs are monitored by IC1100. Any abnormality on the SUB9V or SUB5V lines, triggers the shutdown circuit and the MPU shuts down the unit. The power LED blinks 10 times.
But need to measure the connection SC2, if it short, it will be the SC board.
The knowledge obtain from: Real case of repair by myself.
Information from Panasonic training manual.
