I own an AVR200 receiver, I used it on Christmas for about 4 hours and it just died out on me. Could this be a fuse problem? the power LED light is showing a green color which is normal but, the rest of LED screen does not show any longer. Please help.

Re: Receiver died out
Maybe a fuse in amplifier section is blown out already,caused by busted four darlington transistor or if this amplifier use a STK IC. This is the common problem of the amplifier,try to check this if ever a defected then replaced it with a identical rating.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

do you think your receiver could be a electron tube type ? (that's old) if so your problem could be impedance .
most modern speakers are set to take an impedance of 4 ohms ,, when if your amp has tubes its set to use a 16 to 32 ohm impedance (speakers and amps impedance has to match or distortion will result ) impedance matching transformers can be used to help match load to amp
also speakers need to be rated for there use in wattage , if your speakers have only three amp fuses in them assuming there 8 ohms impedance then they are rated for a max wattage of 88 watts(peak to peak) any more and the voice coils will be damaged from overheating (putting twenty amp fuses in them are a sure way to do exactly that)
also a simple test one can do to older amps is to temp shunt the input together with a speaker connected as a load on output , then slowly increase the volume , no sound (hum / buzz) should be heard or any damage to speaker should occur , if either then there are parts inside your amp that is defective and is damaging speakers
These are all the things that can cause a TV to lose video and what you can do to to fix it.
Check cable connections for tightness.
Make sure equipment is connected correctly and the digital receiver is the first equipment connected to the coax outlet.
If you have a VCR or DVD Player/Recorder connected between your digital receiver and TV, make sure it is set to pass through your digital receiver output to the TV.
If you have a digital receiver, make sure the TV is set to the input that the receiver is connected to ("cable" rather than "DVD" or "game console"). If using the RF output of your receiver, be sure the TV or VCR is on channel 3 or 4, depending on your market.
If you have a digital receiver, please reset the digital receiver. Unplug the box from the electric outlet, wait 15 seconds, plug the box back in.
"A fuse interrupts excessive current (blows) so that further damage by overheating or fire is prevented. Wiring regulations often define a maximum fuse current rating for particular circuits. Overcurrent protection devices are essential in electrical systems to limit threats to human life and property damage. Fuses are selected to allow passage of normal current and of excessive current only for short periods" (wikipedia.com). I don't think that the fuse will blow up. I've had a fuse blow up in a speaker before, but that's because we increase the input to what a level it couldn't handle. In a TV, it's nearly impossible to blow up the fuse. What most likely is the problem is that something is broken or (if it's a projection screen) the bulb may have gone out. It's a simple fix, but takes a lot of time. The link below shows you how. http://www.metacafe.com/watch/1225793/how_to_replace_the_bulb_in_your_dlp_or_rear_projection_tv/
First try plugging the receiver into an outlet that is known to work. If it still does not work, look at the following:
Hopefully there is a fuse on your receiver that is blown. 2 options before it needs to be repaired by a professional:
1. Look on the back for any type of fusing house. It would be labeled "Fuse" and they are commonly held in by what looks to be a flat head screw. 2. If there is no fuse on the back of the unit, it is very possible that there is an internal fuse. Open the chassis, and carefully look for a fuse. It usually is about 1/4"diameter cylinder that is about an inch long. IF you are unfamiliar with electronics, it may be wise to skip the opening of your receiver.
Lightning Strikes can do a lot of damage. Hopefully its a blown fuse.
Unplug the unit. Carefully unscrew the screws for the case. Probably 4 screws, 2 on each side of the unit. Remove the cover. Look for the fuses, and replace with exact same type/specs of the faulty fuse. If the fuse, is on a printed circuit board, be careful dislodging the fuse. Hope this helps.
Your receiver has HDMI version 1.2a and it has bugs/hardware issues. You have two choices. If your receiver is still under warranty, send it out to an authorized service center and they will fix it and upgrade the software and hardware for free to version 1.3a. If not, run HDMI directly to TV from source and optical or digital coaxial to you receiver. Hope this helps
Did you ever find a JVC JR-S501 receiver? I've got one, with a problem. It will play fine for, sometimes half an hour, or sometimes less, and then a loud "POP" sound in speakers. But then will play fine again. Blows fuses on speakers.
