I had a similar problem, and took it to an authorized repair shop(under warranty), the kept it six months, and JVC finally admitted there are solder connections with that model, and six months later, we got a new unit. I will buy Sony next time

You can't. The main amplifier module will probably have a channel blown. The unit is detecting this and tripping into protect mode to stop further damage occurring. Needs to go to a repair place. sorry. ps If you get sound briefly before it trips off then it may just be a speaker wire shorting out! worth checking
The protect message indicates that a problem has been detected in the final output stage of the amplifier. The most common failure parts are the output transistors. Plan on a parts cost between $15-$40. Add in the local labor rate for the total repair cost.
Protect means that a problem was dtected and the output amplifier section has been disabled to prevent further damage. The typical failure parts are the output transistors. Expect a parts cost between $15-$40. Add in the local labor rate for the total repair cost.
You have a short in the internal power of this unit. It is going into protect and shutting itself off to keep it from damaging anymore of the internal electronics. Very likely a voltage regulator has gone bad or a power capacitor has gone bad. You will not be able to repair this yourself unless you are skilled in electronic repair. I would suggest contacting the manu and seeing if they have a authorized repair shop in your area. If not ask around and see who is a reputable repair shop in your area.
I've got a jvc hx-d7 i am working on for a friend, he had it repaired once at a shop with this same problem, they replaced two 42v 2200mf caps. and one A1273 this solved the problem for 8months now its doing it again. I am trying to locate the A1273 to repair it again. Hope this helps.
