Overhaul light (red) stays on!

I have had my amp for a year now and it has been working fine. Sometimes when it gets hot the red light will come on and I just shut the stereo off and cut it back on and it is ok (needed to lower the gain). Now I have a problem where the light does not turn green when I shut the power to the stereo off or lessen the gain on it. It just stays red. Please help! Tipster14

Check the Ohm measurement of your speakers. See if they are about 4 Ohms. The More speakers you stack on an output, the LOWER the ohm ohm Meaning MORE current and heat.
Try stacking fewer spekers on each output and see if the amp runs cooler. However, if the protect light wont go out after you troubleshoot, the amp is damaged and probably meeds some new output transistors. You can search the internet for exact replacement transistors. Make a diagram of where they go and get the right ones in the right places and it should go. If it doesnt go, it might need new power supply transistors as well.

This is not a ovehaul light. It is called the protect indicator. It kicks in when the amp detects a fault on it's output. Disconnect the speaker / sub. Power up the amp and see if the light goes out. If it does you Sub is toast and needs to be replaced. If it stays on then the amp is done.

Gas does not ignite on furnace. Fan stays on even when shut off at thermostat. When trying to start, I hear a click and get a gas odor that stops quickly. Furnace had major overhaul 10 years ago.

The lights on the front panel indicate fault codes dependent on the amount & intervals of the flashes. Fujitsu units carry a 5 year warranty so check with your local Fujitsu store for the agent in your area.

Water heater will not stay lit even after replacing thermal coupl

The pilot must encompass the thermocouple "bulb" in order for the thermocouple to generate enough current to keep the pilot valve on. You must also hold the red button down for a long enough period to get the thermocouple hot. If the pilot is not large enough, it could be due to a clog in the pilot orifice at the pilot itself. Sometimes a couple of passes over the end of it with fine steel wool is all it takes to clear it.

Hope this helps. Feel free to share what you found. Thanks.

Sony kv35s66: No picture, just sound and red blinking

The most common problem (I have fixed lots) is the Vertical amplifier has developed a loose connection. It probably just needs resoldering. As things expand it makes and looses connection you picture goes in and out. The vertical chip is a large black chip that gets hot, over time it degrades the solder until a connection is damaged. Most newer sets have a protection circuit that senses the lack of height, and shuts down the picture tube to save it. When the picture dropped to a line on older TVs and left that way too long it would burn a line into the face of the picture tube. You then had to have the picture tube replaced along with the vertical amp. it's kinda like a screensaver for your TV.

it sounds like your running your ohms to low, check to see what the amp can power and then read up online about ohms and your subs and how they should be wired
