    same problem with a Panasonic TH-42PX60U. Was watching tv. screen went blank; power indicator light blinks twice, goes off for 2-3 seconds, blinks twice and so on. The Panasonic website FAQ describes the problem, but only suggests that you unplug tv and plug into a new outlet (doesn't solve my problem). Help

I have the 52" version of the Viera model. Mine went out last night and started blinking twice over and over again. I suspected overheating so i just went to bed and tried it in the morning with no luck. Then I unplugged it for more than ten minutes and plugged it back in and everything worked fine. I hope this helps.

Panasonic TH-42PZ77U HD Plasma tv has 10 blinking lights


Hello,

Ur power supply board is dead, u know basic electronics’ and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your tv power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

(panasonic TH-42PZ77U plasma) the tv will power on but before the picture comes up it powers back off. Red power light is flashing.


in protective mode the tv does not turn on and light is blinking, typically we must proceed by elimination as some faulty sections are preventing the tv to switch on. unplug the output power connectors from the power supply until the latter stop clicking. if it is still clicking after every of the output rail have been disconnected, then the power supply itself is faulty.

hope this helps!
