AWR1 isn't working. Batteries new, hear thud when electricity con

Connected so I know that the wire is okay. I suspect a power supply problem, is that common to these radios? No other response from radio, just the thud.

The power supply in your BOSE is easy to repair. Can you use an ohmmeter? The voltage regulator IC has 18V in and 10V out. Also Q1 often shorts from base-emitter. Both are easy checks if you know how to use a meter, and a cheap fix to get your radio working. Heck, I would BUY your radio if you want to sell it non-working!

Well im working on a bose radio now it is the am-fm clock radio and so far the dual bridge amp IC is bad along with a j111 n channel mosfet. these conponents are cheap and if you can do it i would suggest doing it yourself. the main capacitor check the soldered connections the positive joint is known to crack from the print on the board.

Hi Got a 2013 sgh honda 125 bike hooter just went

First check the fuse is okay. If it is okay, horns generally work by earthing when you press the button with the ignition on. Turn your ignition on, find the 2 wires that are connected to the horn and check if there is power to one. If there is, earth/ground the other connection and see if it works. If it does I would suspect the wiring. Alternatively, remove the horn, connect one of the electrical spade directly to the battery live and then earth/ground the other spade. If it doesn\'t sound then it is faulty and cheap to replace. Of course check all connections are clean and well connected.

Could be internal damage. Put a socket and wrench on the crankshaft pulley and see if engine is seized up. The thud is worrying, suspect major damage if the crank won't turn all the way round. If you can't turn the engine by hand, you will need a new engine (or new vehicle- that is a pretty old suburban, almost ancient to be needing a new engine!)
If engine still turns by hand, have your starter tested.

I have a HP Omnibook vl6200 running WinXP Pro. Works properly on the AC power, but shuts down if AC power is removed. Installed a new battery pack and battery monitor software showes battery is fully...

The first thing is to check if your battery is still okay by taking it off then measuring if it has some electric charge. If you are able to use a measuring meter then that's super but if you are not able to you can use a 24V truck light bulb and connecting with 2 wires to the positive and negative side of the battery. If it lights up brightly then the battery is okay. If it's got no electric charge then there are two possibilities either the battery is not okay or the charging system of the laptop is not working. Supposing your battery is okay. Then you need to have your laptop checked on the charging system. Remember laptop batteries do not last forever they actually deteriorate to until they are completely unrechargeable. So the Battery is my prime suspect.

Computer will not turrn on hp a 1230n

Hi Raul,
Try this following instruction to isolate the problem.
1. Check the power outlet/AVR if it has an output, if okay,
2. Check the wire if okay, often times, the wire is damage or open. try to use another cable.
3. If the wire is okay, try to isolate the power supply, remove the power supply connection to the board and short the color gray and green wire to see if the power supply is working, if the power supply turned on then its ok.
4. It the power supply is working, try to check the power on button, it might have a problem. to override the power on button you can short the pins inside the board where the wire from power button is connected to motherboard.

Make sure you have connected into the correct video port. DVI should be used for LCD monitors and VGA should be used for CRT monitors. Since both ports look the same people often get confused. Try it and let me know.

Bose wave AWR1-2W problem

I purchased one of these radios from a thrift store today. It had the exact same problem.

I replaced a 2SC3792 transistor located near the transformer/power supply section of the board. The transistor had a short between two of its leads.

once replaced with a substitute, the set came on and works perfect.
