Question about Panasonic Viera TH-42PX80U Plasma TV
I have a TH-42PZ80U Panasonic Plasma TV, when I turn it on, the red light flashes 10 times then it will stop. Then after a few seconds it will flash 10 times again then it will stop, this will go on and on... don't know what to do.
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.
