SOURCE: Panny TH-42PZ80U Plasma TV No display on Power-up

I had this same exact issue. Panasonic sent a repair tech to my house since I was still under warranty. The tech was able to fix me up in about 10 minutes. He replaced the "brain" or A-board and now I'm back in business. This is NOT a power supply issue. The brain is the circuit board that has all the inputs attached to it (component, hdmi, etc...).

hope this helps!

I plug in my TH-42PZ80U and it doesnt turn on but a red light blinks ten times.


Apparently this common problem is due to a faulty power board. Contact Panasonic for a replacement if it's under warranty (hopefully) or a local repair shop. Good luck!

TH-42PZ80U Panasonic Plasma, red light flashes 10 times


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.

Trying to find out what parts needed to fix panasonic th-42pz80u


If your TV model is TH-42PZ80U, and you want to replace the whole power supply unit, shopjimmy.com has them for $160. But for each parts# on that board itself, you need to find a Service Manual to look up that part.
