Purchased product last month. It worked for a few days and then the volume would not function properly---stays at low volume even if knob turned all the way up.

There are a few potential issues that could cause a gas furnace to light but not stay lit when the control knob is released. Here are a few things you can try to troubleshoot the problem:

1. Check the gas valve to make sure it is open and functioning properly.
2. Check the gas pressure to the furnace. If the gas pressure is too low, it can cause the furnace to go out when the control knob is released.
3. Check the thermocouple for proper installation and alignment. The thermocouple should be seated securely in the pilot assembly and should be properly aligned with the pilot flame.
4. Check the pilot assembly for any debris or obstruction that may be causing the problem. Clean the assembly as needed to remove any debris.
5. Check the control valve for proper operation. If the control valve is not functioning properly, it may not be able to supply the necessary gas to keep the furnace lit.

If the volume knob on your model #bc345crs is not functioning properly, there could be a few potential causes. Here are a few troubleshooting steps you can try:

1. Check for any debris or blockage around the knob that might be preventing it from turning properly. Clean the area with a soft cloth to remove any dust or dirt.
2. Try turning the knob in both directions to see if there is any difference in the sound output. If the knob only seems to work in one direction, it could be a sign of a faulty potentiometer, which is the component responsible for regulating the volume.
3. If cleaning the knob and turning it in both directions doesn't improve the issue, you may need to open up the device and check for any loose connections or damaged components. This should only be attempted by someone with experience working with electronics.
4. If you are unable to diagnose and fix the issue yourself, it may be best to bring the device to a professional for repair or replacement.

Be sure the power cord is plugged in to the a/c outlet fully. Take a table lamp and plug in the same outlet to verify power is good. If no power, check for circuit breaker tripped in main breaker box.
If problem seems to stay with tv, I would contact seller. You should have at least nine months of warranty left.

you can lock/unlock above functions by pressing zoom and negative volume control keys simultaneously.

The simplest thing to try is some compressed air directed to the knob. This would clear out any dust or dirt that may be obstructing the knob. I am not sure what you mean by power cut so I am shooting in the dark here. If you mean a power surge that caused the volume to quit working then I would suggest an external volume control such as http://www.amazon.com/Koss-155954-VC20-Volume-Control/dp/B00001P4XH/ref=pd_bbs_2/002-2257004-6895258?ie=UTF8&s=electronics&qid=1194009359&sr=8-2

Guys, I might have accidentally found the problem because the fix worked for me :). I have the RX-V995 and for the last 2+years or so, I had resorted to getting up and using the knob manually for volume control. System will show 'voluem up/down' in the display, but the knob didn't rotate. Same problem as yours.

I was getting ready to buy the service manual, find the knob motor which I thought was the main culprict and replace with a new one.

So I took out the top cover (just a few screws), the front face-plate (again just a few screws. The inner details were all visible. The volume knob circuit board was vertically placed. They were all covered in a good layer of dust. I got my Dyson vacuum cleaner and gently and carefully tried to **** up all the dust that had settled down. With soft front brushes, I agitated the dust I couldn't reach with dyson wand direclty, once dust were loose, dyson did a great job even with picking up those last dust pieces.

I couldn't succeed in taking apart the volume knob circuit board, as I was still awaiting for the service manual. I put all the covers back on and guess what? I used my remote and the knob was moving again. Responding very well, the knob made the full turn, when I was on the remote. It has been working perfectly for the last few days now.

I think I know what was happening. Teh top of the RX-V (and I am sure many Yamaha receivers) are very porous to allow for good heat dissipation. Over time, this allows a large amount of dust to collect on top of the parts. Most parts are electronic (not mechanical) and hence don't get affected by the dust. But the few mechanical parts might have adverse affect if dust settles down in between the rotating mechanisms.
My volume knob had stopped responding to remote command, very slowly. Initially it worked a little, missed a little, then it missed a lot and eventually it didn't rotate. That proves the theory to some extent that if the motor had completely failed, it would stop working from the get-go, not intermittently. Dust build-up provided intermittent contact between the parts and hence the response was intermittent.

The dyson vacuum did a great job in pulling out those fine dust from such parts and amazingly, things are looking very good at present. Honestly, I hadn't the slightest hope that vacuuming would fix the problem. I had vacuumed to make it easy for me to work on the parts :).

So, it doesn't hurt at all to just give it a try. Do open the covers so that you can reach closer to the real boards and parts.

Good luck and let us know!!!
cheers

Please see my solution posted on Mar 13. No other brain waves yet!

There is no function to do this as part of a whole suite of date manipulation functions, but I seem to have imagined that, as I couldn’t find. I was dreading having to do lots of nasty date arithmetic, but then I discovered that the zeroth day of a month is treated as the last day of the previous month! So the last day of the month for the date that’s in cell B3 is simply:
=DATE(YEAR(B3), MONTH(B3)+1, 0)
It even works across year boundaries, so DATE(2004, 13, 0) really does give

Take the scew out and take it to a hardware store to get an allen set screw put that in and tighten with allen wrench. BIG RED
