Capacitors, in the power supply area. Just about all flat panel tvs use cheap Chinese made capacitors. They either dry up or short. Fix is simple, and tv will be working in no time. A special monitoring circuit checks "ready" voltage, and if it's not there, tv will not operate.

    As far as I can tell, all the capacitors physically look good, no bulging tops or melted areas. How do I know if that is the problem?

    I'm sorry I have not responded, stupid gmail was putting my legitimate emails in the spam box. Capacitors can look undamaged as well, only thing you can do is chance a replacement on the main capacitors. I have had capacitors that look undamaged, and replaced them and viola, tv works. It's just intuition sometimes. Something will tell you if a component is bad, go with that first hunch. Usually, you'll be right.

HI. My Yamaha D80 while playing gave a burned smell and than sound quit. Rest works. I opened rearcover and notice 3rd fuse in the back was blown. Changed it. Blew again. So I stopped fidling around.

If the fuse blows and a smell of burning is present then its obvious there i a fault somewhere ahead of the fuse, the fuse is a protection device.

Dishwasher has no power to control panel and fused spur arcing

You state that the fused area was arcing. Any time you have arcing, in time that area will carbon up and stop working. Sound like a loose fuse holder or bad connection in that area. Shut off power, remove fuse and clean area completely. make sure fuse fits tight in holder. Check all connections where you noticed the arcing for black areas that are burned.

Smell of burning rubber on offside rear wheel. Intermittent. Kia Ceed 113bhp 1.6

I think you are on the right track with the hand brake/ parking brake. A vehicle can still drive if its slightly engaged and you would notice some sort of burning smell from the area. Try engaging the brake and disengaging the brake a few times and see if it releases completely. There may be an issue with the line causing it to "stick" here and there. Good luck! Cars are complicated but troubleshooting the small things before spending hundreds in labour is always wise!

Electrical hot smell from fan area, not has quit

Hello, electrical hot smell from the fan area means you have a burnt fan which inturn affected other parts of the ice maker. That is the reason why the ice maker fails to start up when you plug it.
You can only fix it by replacing the fan and probably other affected areas by troubleshooting it.
There is nothing like reset.

Take care

Electric dryer internal short

Make sure that the dryer is disconnected from the wall outlet before doing any repairs on it. Electric dryer work on 240 volts AC and this could hurt or even kill you. loose connection on the terminal block will cause the wires to get hot. and melt the terminal block and wires and the pig tail wires. you will have to replace the terminal block and pig tail wires and make sure you use the correct bolts and make sure you tighen them. let me know if this helps.krazytech
