Press around board where power comes in to see if solder connections are weak. where the red and black wires come in, it's 12 volt power to the board its usually a reverse polarity diode, its black with a silver stripe around it, its job is to make sure it wasn't hooked up wrong, you could unsolder it MAKE SURE EVERTHING IS HOOKED UP CORRECTLY, turn it on for a test, if it works find a replacement diode.

I shut down the fridge. Not getting any power to it now. I have checked breakers and fuses. There is power to 110 outlet where it plugs in. No power to gas valve. What do you think the problem is?


Your Norcold refrigerator is powered by 12V DC, not 110V AC. You need to check input power at the power board. If the fuses are good and you have good 12V to the refrigerator, check to see if you are getting 12V past the 5amp fuse on the board. If not, you may have a bad board.

Sounds like you have an antenna problem on the UHF side.

Not getting power


Pull the fuses and check them. Make sure that the wires have power. Battery power should always be on(12V) and the remote wire should have power only when you turn on the radio. Also check to make sure you have a good ground to chassis. If your wires have power and the amp's fuses are fine, then the amp's fried. At that point if it's not under warranty, open it up and see what you find. I may be a cold solder point that need re soldering or a burnt lead on the PCB board. Pay close attention at the power end of the amp, where you hook up your wires, check around there especially.

Dometic 2652 does not cool that well. Food spoils. Placed 12V fans on fins and another on the lower portion. 46-58 degrees. No help. Replaced with circuit board #3308741.002 and no-go. I have no 12V power...


Hi


There could be leak which causes the no cooling state in your unit.To check the cooling ammonia system, the 110v heater or the 12 Volt heaters can be hotwired direct to a power source, this will check the cooling system, The 110 V is best to check. But you need a repair person to get it diagnosed.


Please get back to us if you have further query else please accept this particular suggestion.

Fuse and power supply look ok to the eye slight static sound on audio tiny flash intermitent inright corner on video, any clues? power diods check good ,nothing looks hot or burnt There is a second board...


Your power supply on the dc output should have the floowing DC voltages, 5v, 12v, and 24v. Just start probing the connectors of the power supply. 24v is needed for the backlights inverter board, 12v for sounds, 5v for logic board.

My amp does not want to turn on


check in line fuse, make sure you have a good ground, and make sure the remote turn on wire is connected to a 12v power supply that only comes on when your car is on (that wire sends a signal to your amp telling it when to turn on and off.

Woofer will not turn on. fuse was bad but i replaced it and still no power.


Had the same problem, no power from the sub, no light. Opened the box, fuse was bad, replaced the fuse...pop...blew again. Found out that on the bigger middle board next to the power plug there are two capacitors on either side, the inner one burned and crumbled to pieces. I called Kenwood, they said that I would have to bring it to a Electronic Service Specialist that they will give you a number to in your area...or...Ship it yourself to their East Coast Center in Virginia. I already asked if Kenwood is going to send an RMA or Shipping Label and they will not. You will be responsible for the shipping there, but they will pay for the shipping back. Kenwood's East Coast Center in Virginia's number: 757-340-1702 - Good luck

Westinghouse LTV-32w6 power light on, no video, no sound


One thing is to make sure the inverter board is unplugged when testing the voltages. A shorted inverter will shut down the power supply if the fuse dosen't blow first. There are fuses that don't look like fuses so they can be missed. The next thing would be to look for a connector from the main to power supply and see if there is a pin labeled power on or p.on or similar. The main board should turn this line high(5V) when you push the power button. If not you probably have a bad main board. Unless you can find good used boards they are both expensive. Around $200 for PS and $300 for main.
