DO NOT USE EMMERY PAPER, It will remove the surface coating. Use a 95%+ isopropyl alcohol on a Q tip, a pencel erasor.

My Polaroid iE 3035 camera switches off as soon as I switch it on. It has new batteries in it. There is a green light flashing at the back


A flashing green light can mean it has problems accessing the memory card.
Check the card is not Locked and if all con acts are clean and shiny.
Never use zinc carbon batteries, not even new ones, because they can't give enough power. The best are NiMH rechargeable batteries of a camera.
Contacts can be cleaned with a dry cloth or cotton swabs. Never use sharp toosl in or close to a camera.

Frigidaire electric dryer (FEQ1442CES) keep flashing and beeping even after cleaning lint filter.


Good Afternoon Friend,

I understand that your Frigidaire dryer, model# FEQ1442ES, keeps beeping and flashing lights. I also see that you have cleaned all the lint out and your appliance will not run more than about 10 seconds. I suggest contacting your local authorized technician for further assistance. They will be able to diagnose your appliance, determine what is causing the lights to flash and the beeping, and repair your dryer. Hope this is helpful.

-Best Regards-

Best way is to go to a shop that has a computer analyzer for cars. Before going, check to see if the connectors to your car computer is fine. Sometimes, it only needs to be taken off then putted back as the contacts have degraded somehow. Try cleaning the contacts with contact cleaner that does not melt plastics.

My kodak esp 3 printer has a red flashing light on both inks and a flashing E. I've changed both cartidges and still have the same problem.


The printer contacts do not connect with the printhead contacts. The contacts may be dirty; the best way to clean the contacts is by reseating the printhead multiple times. . If that's doesn't work you will need to contact Kodak for a new printhead. Log onto www.kodak.com and find the relevant support team. Give them a call. The warranty on your AiO is 15 months so be sure to make your printer in warranty ;-). (By the way, most of the agents are happy if you tell a little white lie about your printers warranty coz it gives them less work. Also remember begore calling, ITS NOT THE AGENTS FAULT THAT YOUR PRINTER BROKE!!!

Ntn7143cr battery won,t charge. put in charger flashes red then green.


Clean your battery contacts on the battery and charger with a pencil eraser to assure good contact. Flashing red or flashing in general usually is the sign of a too low to charge battery, a shorted battery or a bad connection. In some instances, a battery will begin to charge once left on the flashing charger for an hour or so. Try this and see if the light becomes constant. If so, it is charging. If it still flashes, replace the battery.

Best regards.

Batteries leaked, now it won't work


When batteries leak, that fluid can runn all around the inside nad in the wires and disolve the tiny connections on the circut boards. If the contact are really clean and shiney bright, and the flash won't work still...it may be time to buy a new flash.

Nikon SB-800 flash - needs to be reset ?? or repaired ??


Try reseting the flash itself, press and hold the "Mode" and "on/off" buttons together for 2 seconds approx...this should reset the whole flash.

If that doesn't work try unlocking it by pressing the "on/off" and "Sel" buttons together, the padlock should disappear.

With respect to the corroded contacts you just need to try and clean them as best you can...but it sounds like you have really bad contact with the battery and hence a serious voltage drop, hence the dim display and lack of the red ready light.

Thanks
Mark
