Re: POWER ON PROBLEM
Well, I know that u will overload it if u use any 4 ohm speakers on it. And a LOT of center channel speakers are 4 ohms.
Also, it has problem working with 5.1 (optical or coaxial).
If that is the case, try to run it on stereo...

Well, I disassembled the unit carefully. And I've found that diode SR303 was blown. It's very easy to find near huge pulse-code converter chip. This diode is used at power supply stabilization for amplifier that has a D-class i.e. pulse-code amplifier, and for CD part. Testing of this diode confirmed that it's dead. After a couple of days received the diode from shop, is very cheap. Changing the diode recovered all the functions of the unit. Now it works fine.
Resume: The diode was burned as a result of incorrect connection to line input. The owner of the unit haven't seen that a volume level was at maximum. The connection of line input overloaded the maximum current capacity of the diode and it was blown. As for it, I've seen that in that circuit in reality must be used a stabilization chip, that is not so cheap like a diode. I think it's a constructor's error to change the chip, that is overload protected, to a simple diode.
Waiting that my info will be useful because it´s a most vulnerable part of JVC CA-FSX3. And don't overload the amplifier!
According to Page 46 of the LBT-W5000 Operating Instructions:
"The display stars flashing as soon as you plug in the power cord even though you haven't turned on the system (demonstration mode).
Press DISPLAY (for LBT-W5000 / W300 / XB700 / XB500) or DEMO (STANDBY) (for other models) while the system is off. If the system is in the Power Saving mode, press POWER SAVE / DEMO (STANDBY) (for LBT-W5000 / W300 / XB700 / XB500).
The demonstration appears automatically the first time you plug in the power cord, or if there is a power outage lasting longer than half a day."
I tested this today, as my LBT-W5000 was in Demonstration Mode. It definitely works. The only catch is (at least on the W5000), and it's a minor one, you have to reset your clock afterwards.
Hello, HiFi system actually turned Off when you press power button and display of hello, heavy, vocal etc is demo mode of this system and it activates when unit goes to power off. You can change its settings like not to show demo mode etc and this procedure is described in owner's manual. Thank you.
The protect message indicates that the output amp section has a problem. Normally this requires the replacement of the output transistors or the output amp pac. Expect the repair cost to be about $20-$60 for parts plus the local labor rate.
Turn the system on and press the "Clock/Timer" button (located above the eject button for Deck 1). The clock will appear. To change the time, simply hold down either the < or > buttons (the ones you use to change radio stations and begin CD/tape playback). Press "Clock/Timer" again to lock in the time.
Press POWER to Turn ON the unit.
Press CD/Door OPEN.
With the Doors Open, on the Inside Right is a "Clock Set" Button... Press it once.
With the Hour blinking, press the "CD-Tuner-Skip" Up or Down Buttons to set hour.
Press the "Clock Set" Button again to make the minute display blink.
Adjust the minutes the same way.
Once the hour and minutes are both set, be sure to press the "Clock Set" button
one more time. Now the Hour and Minute display should no longer be blinking and
you should be good to go. (I just figured it out for myself.) Hope this helped!
