Having problems with your Flat Panel Televisions ?

It seems as if there is no power to the unit even though it is plugged in. I disconnected cord from unit and checked with a meter and read 120 volts so the plug is good. Still no power after replugging into unit.



Answers :

Take the cover off the TV and remove the power board. It is not too hard to do.

\015\012If we fix it the price will be 75% of the lowest you can find a new board for, but no less than $40 and no more than $90. (sigh...that my change over time too)

\015\012If you wait a little we'll post a guide on our blog http://blog.coppelltvrepair.com on how you can actually test it to see if it is functional. If it passes the test then the problem is in your main board, but it will likely fail it - it;s a known issue.

Testing is not much different than with other power boards, so you can see other articles there on how it's done if you're impatient. Just bear in mind...be extra careful!

I have a Panasonic TH50PZ77U plasma. (1) recently the unit would power off, without warning. (2) The power light blinked several times two nights ago, but finally came on. (3) Last night, no power light on the front of the unit, and it will not turn on. The unit is plugged into a surge protector and all other components plugged in are operating correctly. I have read through several forums on similar Panasonic models, and a "power supply" failure seems to be way to common.

TV staying on one channel only. Tried info, menu, mute power off. When it turned back on it showed the menu and option to reset, as per advice i have read on here. However the select / ok button on the remote does not seem to select the option, from what i read it is then supposed to switch itself off, when turned back on, it should then allow me to plug and play and start from the beginning as i did when it was first purchased. But it does not? :0( any advise welcome. Thanks in advance
