I have a panasonic viera plasma tv, i believe the model # is tbmu514 and the volume on the set works but it will not go up and down for some unknown reason.

1.You may have the magnet of a speaker too close to the TV.
2.Turn off other electrical devices in the house one at a time.
3.Faulty cable.

Puzzler.

SOURCE: Panasonic Viera TH-42PV7HS Plasma keeps shutting down

hi there, have the same kind of problem twice so far after was bought for me as x-mas present (although my viera isnt plasma, its an LCD TX-32LMD70A)..

I Pulled out the mains plug for about 10-20 seconds and then plugged back in (power button at top was pushed in, in the on position, so when the power was on, the tv just goes straight on). It then worked.

i would however like to know why this happens ( i really hope this isnt a hardware problem, as like many others... its only months old!!)

hope this helps

SOURCE: panasonic viera tv won't turn on. Power light

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

SOURCE: what does it mean when my plasma tv turns off by

Basically when it turn itself OFF automatically all the time, the TV goes into "Protection Mode". This happens when there is a damaged circuit board inside the need to be replace and turn itself OFF to protect the other ones from being damaged.

A TV service tech will have to look at it to find out which boards need to be replace. There are about 7 different boards in your TV that would cause this problem.
