It's almost certain the two are connected. I suspect that one or more of the devices on the heat sink has shorted (acting like a piece of wire) and has blown the fuse.

B&K AVP2000 left channel not working


Yes amps buzz when something gets near them - say a pen or probe and if you know what it is safe to touch a finger! Fortunatly for you the left channel is the same as the right. So if you believe it's the pre-amp work backwards from the where the power amp connects to the pre-amp, going through the pre-amp stage by stage - prodding the parts. Remember a buzz in the right a buzz in the left! No buzz in the left but one in the right fault found!
Ignore the power supply it's nothing to do with that as it's common to both channels.

Hi i have a nordmende tv and was working until it was plugged out of the mains now it stuck on standby and i dont have remote its an nw32lqt any ideas for easy fix i ve tried letting capicators drain no...


Hi,

while the TV is on standby, press the channel + or channel - button on the TV and the TV should power on.

If TV doesn't power on after pressing the channel button, then it means your TV is having a power problem. But I don't what to believe it is a power problem.

Let me know if press the channel button does not power on the TV so that I can explain further on the cause and way to fix the problem.

Yours sincerely.

We have a 4 year old Visio HD TV. Recently we had time when both the HD channels and going up and down using the channel surf buttons did not work. The low Def channels would work and entering the channel...


I don't believe that it is cost effective. BUT, if you have Comcast, you will now need a cable box to watch most channels now. I believe they stop at about channel 12 without the box. It's their way to stop cable thieves, but it's an inconvenience for the rest of us.

If this isn't the case, you might want to try to contact Vizio tech support www.vizio.com. or try to reset the TV - unplug the TV, press and hold the power button for 30 seconds, repeat. Plug it back in and see if it helped.

One of My speakers does not work, When I switched the speaker wires the problem followed. I believe maybe a blown channel. """please help"""


Yes, one of the power amps has probably failed. If the channels are seperate, then another possibility is a bad input connector. These do get broken when cables are tripped over.

My tv is stuck at one channel. Which controller board has to be replaced? The Key controller,LCD controller, or what?


I got the same problem, TV stuck on one channel, what I did was, I remove the cable (fron the back) for a minute and then reconnect, work perfect, well, better than try to return the bloody thing.
Good look with your.

I dont know how many watzz is my amP!


200 X 4 does mean 200 watts times 4 channels. In other words each channel pushes out 200 watts. I believe u have a total output power of 800 watts but check with ur manual and if u do use that much power make sure you check for overheating, specially if its used for bass. Soundstorm amps cant take much of a beating so be careful.

I went to add/delete channels in my menu on my symphonic and it let me scroll through the channels, make sure you have them all set to add (by pushing the volume buttons to make them light blue instead of purple)....after adding all of your channels (or just the one if you use dish) just power the tv off while on a channel and then power back on and you should have tv.

Insignia 32 inch LCD TV: Can not change Channel or Volume !


I have one in my shop with the same problem. Power is the only function that works. I repaired the power supply six monts ago. Now it looks like a bad digital processor board which is non-repairable. I can't believe what's happened to the tv business. Absolutely disgusting!
