1999 grand am speedo dosen't work. put a new senser in still dosen't work


Sounds like you have some electrical corrosion in a connection somewhere in that system causing the low voltage. Take the connectors apart and clean them and that should help

My mitsubishi model ws-65511 green lite blinks no power


Hello
The power supply regulator board has the fault. Just replace suspected capacitors on that board. If it does not help you, replace the board as card basis. You can buy this board from the authorsied service center for Mitsubishi at your town. I've the repair book to your TV, but it is in PDF format, and I can't send it to you by this window as, this window dosen't allow me to send any PDF files by it.

I just got the mp3 player. ive been charging it but when i disconnect it from my computer it shuts off and wont turn back on. HELP!


Some older computers that have USB ports that limit the output to 5V @ .5 amp current. Depending on your MP3 player, it may not be sufficient to charge the player. This was the spec back then. Since then, new USB specs call for 5V @ 1.0 amp current - a two fold increase in current.

You may have better luck connecting to a powered USB hub instead. If you're only looking to charge the MP3 player, you don't even need to connect it to the computer. The powered hub gets powered by connecting the ac adapter / power supply to a wall outlet - instead from of the computer's power supply via mother board.

The above assumes there is a good, rechargeable battery; a functioning charger & USB port in the MP3 player and of course, a working USB cable. If any of the above is faulty, you'll never get the MP3 Player to accept a charge. You should try different computers, cables and ports if possible.

Good luck!

Mine board dosen't work. I redo the solderein of the main ac power and the ones of the 100uF\450V condenser. It work good for 2 hours than it turn off.....and it appaer dead.... what can i do?!?!?!


That caps is for the Main AC side of the switching power supply which supplies about 160vdc (you can measure that voltage on the caps legs) to the MOSFET that drive the step down switching transformer that produces the 5v for logic board and the 12v for the backlights inverter circuits. The power supply is always running even if the power switch (soft switch (momentary)).
So you need to check those two DC voltages without hitting the power on switch, they shoud be present. You can also hook up the lamps to test the power supply function.

I just bought 2 new catridges (black & color) but the color ink dosen't print.


I'm not familiar with Lexmark but I think your printer is set only to print on black cartridge (black only option) There's something wrong with the settings. Check the settings, look for the color options.

Using A580 with DLink Router. Incoming & Outgaoing calls OK for about 2 Mins then call breakup. Signal & Battery showing OK. Person at other end can sometimes hear everything OK.


THis sounds like you have ether a bad modem router or connection. You will not notice it with a webpage but VOIP uses UDP a real time and stateless. Which in a nut shell means the phone send a stream of data and dosen't care if the other end gets it or not it just sends. If you have a bad connection to the internet the phone will get interminit packet loss aka: audio breakup. So to debug and fix this.

First eliminate the variables:
Connect the Phone Directly to the Internet Providers Modem.

Reset or power cycle the modem.

Try to call out.

If it is still breaking up contact your isp for support.


#######################

If the router is the Cause of the issues:

Try to go to Dlink.com and flash the newest firm ware to the router.

If that dosen't resolve it you may need to get a new router. I recomend a linksys router as they tend to last about 3-5 years.
