We have a model B40 that seems completely dead. It was working earlier today and now we have no lights or sound at all. We have tested the plug and it's fine with another appliance. We had this happen before and Keurig sent us a replacement machine and only wanted us to send back the coffee holder. Is there anything I can check like a blown fuse or fusible link? The serial number is 45.0100.1074773. Bill

Bad cold control sounds like. Try unplugging from a while n plugging it back in

are all the radio function dead.?????
what are they, radio, AM and FM dead, cassette, CD,?
if only the radio is dead. (static) then the antenna is bad or its lead in coax wire is bad. or fell off. etc.
the amp (audio is good) as you heard the static.
you can unplug the antenna, wire, from radio and plug in any
lenght of wire to test the radio, any radio can be bench tested this way. and is in any shop.

its very rare today for any head end radio unit to be only a radio.
so do the other features (other audio sources work?) try them.
if they work then the antenna is bad.

1. There is some confusion over models. I've seen "B40" models and instructions with only one size cup button, both labeled B40. I own one stamped "B40" on the bottom, and it has two buttons -- small and large. FWIW, small = 8 oz, large = 10 oz.

2. These reset instructions from another site seemed to do something
What to Do If Your Keurig Won Brew Cup Barista

So.. this is what I did that worked for mine: 1) Hold down Auto-Off and LARGE cup at same time. (all lights should hold steady ON) 2) press SMALL cup while still holding Auto-Off and LARGE cup 3) Release all three, press LARGE cup again.. all lights should go off. 4) Unplug for about 5 - 10 second, plug back in. SHOULD WORK!

3. On *_my_* B40, remove the K-cup, close the door, fill the reservoir. Unplug and replug the B40. All lights should be off.

Pressing "Auto Off" and "Large Cup" together will turn on 3 lights (Heating, Add Water, Power) for about 3 seconds. Doesn't matter how long the buttons are pressed or what order they are released.

I tried lots of add-on combinations: e.g. press button x, press x multiple times, press x while lights are still on, press x after lights are off, press buttons x and y together, press x then y, press x and/or y while still holding Auto and Large, release Auto but not Large and press x, etc.

Nothing gave any confirmation that a reset was accepted. All lights always turned off after 3 seconds. Maybe Reset is only 1 step, i.e. Auto+Large together?

see this causes and fix it. God bless you
No Lights or Power, Unit seems Dead First check is the main fuse of the unit. On countertop units, you will need to take the shell off. The fuse will be close to where the cord comes through into the unit. OTR units, this main fuse is usually behind the control panel or possibly behind the vent. Usually the fuse is obvious if blown, otherwise test with an OHM meter, if open, replace fuse.
Some brands will also have a thermal cut-off fuse in the incoming voltage line to the control board. Older Maytags and Samsungs have this fuse in it. This thermostat looking fuse is usually above the oven cavity somewhere under the outside shell. Sometimes you can get to it through the vent of OTR models. Test with an OHM meter, replace if open.

Check the other coffemaker that I replied to on this site today, that had the same problem, and follow the instructions I left there.

You do not need to remove the battery to charge the battery. When you connect the charger you MUST be careful to connect the charger's positive lead to the positive terminal to the battery and the negative lead to the negative lead to the battery before you turn on the battery charger. Connecting the charger leads the wrong way around most likely damage the vehicle's electronics.
When you finish charging the battery turn off the charger before you disconnect the charger leads. This will prevent arcing between the leads and the battery.

Now the tv it is completely dead no LED power light indication is on at all or the tv power LED light indication blinking too?Check the power source?Tries tv unplug,replug it back about an hour later for the tv do a resetting itself back to the factory setting,tv should be working again.If not the tv power supply board it is dead,that the board where the tv power a/c cord plug into it.Tries websites like Shopjimmy.com,Ebay.com to buy a whole new refurbish power supply board for the replacement.

This is what I would do before chalking this thing up as a hard ware failure try connecting thie to another adpator if that then does not work you indeed got a HW failure with the laptop and the motherboard would likely need to be replaced, Get it evaluated by a technition the geek squad at any best buy wull be able to test this real quick for you do not loose a good laptop over a faulty adaptor trust me this is where the issue could result.

thanks and please do leave postive feedback, ratings for your free naswer today.

Be sure you checked all 3 fuses, F3 5amp, F9 7.5amp. F12 15amp. Test with test light the red and black wire in start, the dark blue and light green in accesory, and the violet hot at all times. These are all in the harness to the radio. Then test grounds by clamping the test light to battery positive, and check the black wire and the two black and light greens. If both units are good, there's gotta be a bad power or ground.
