The TC-L55E50 has an optical output located on the rear of the TV. Simply connect the optical cable from the TV to the amplifier.

Your power suply is defective and needs repair.
Or the power amp is shorted will blow inside fuse power line
distribution.

Mike,

In its most basic form, a sound system consists of a signal, amplifier and speaker. If there is a problem with any of the three - unexpected results can occur.

Swap the speaker with a know good speaker. If it still doesn't work, it is not the speaker. Change the signal. This is usually done by selecting a different line level input, ir connecting a different device to the input(s). Your device may not have the ability to do this. If you are able to choose a different input, and the problem still exists, then it is probably not the input, either. That leaves an amplifier problem. The amp could have failed naturally, or due to an open or shorted speaker connection, connecting the wrong impedance value speakers, playing at a very loud level, etc. Some amps have a fuse or circuit breaker that opens in many of these situations - your may or may not have this feature. If it does, there's a chance it didn't open before the damage was done though. Needless to say, if you replace the fuse or it doesn't have one and the problem still exists, it will probably need to be sent out for professional repair.

I hope this helps and good luck. Please rate my reply - thanks!

Never connect incompatible connections. Speaker outputs are for speaker inputs. Period.

The various inputs on this or most any amp are for Line Level signal with the exception of anything explicitly labeled "PHONO" as that would be for a non-preamplified turntable ONLY.

From what I have found online, Lab-In was a NAD feature that restored the frequencies that were rolled off when turntables were being used in the (assumed) preamplifier that fed this amp.

"NAD belleived at the time that practical PHONO stages and the preamp and power amplifier stages be rolled off at subsonic frequencies to prevent subsonic wow and flutter from Turntables and supersonic frequencies (EMI/RF/Radio) signals from getting into the system in the first place. Their notion was that if your ears cannot physically hear it, then why amplify it. For the PURIST, there were a set of LAB IN amplifier inputs with more extended response called "LAB IN" inputs"

Use the Lab In's UNLESS you have a turntable source.

Hi...

From a websearch is seems E&W is in S. Korea

Maybe they can assist

Depends on the problem

Either you will have to see a repair tech or get your money back. Sorry about the bad news. If you have a blown output (which is what you probably have) then it is more of a problem than a regular consumer should attempt to repair. Sorry.
