My laser won't work. Does it have a battery? - Hitachi C12RSH 12" Sliding Compound Miter Saw withLaser

have you replaced the batteries to correct the problem as left on for several days would discharge the batteries.

Likely it's dirty battery contacts. Clean the contacts on the battery tray, and the coil springs in the laser, and it should start.
If not open the laser, reinsert the battery tray with good batteries and test the voltage at the battery connector at the rear of the laser.
Check for signs of water damage or corrosion.
short out the power switch, to make sure it's not the problem.
The switch circuit board, power connectors, battery tray, and motors are the only electronic parts still available for these lasers, and that is only because they share them with the RL-H3A, which was only discontinued in 2011. If none of the above will make it turn on, you'd need to find used parts, and try and rebuild it.

Most likely a dead battery. Easily replaceable at home. The factory won't tell you that.

you may mean a plymouth laser but any how it sounds like it needs a new or neutral saftey switch or an ajustment of this switch which is located on the ******

if you move the cable around just right will it charge?
if not u could have some kind of damage. did you drop it
i would just try buying a new battery on ebay they are usually pretty cheap online.
if you charge your phone alot and overnight. thats really bad for the battery

Most likely the laser is weak. It has been awhile since I have changed a laser in a psp. But first off you should clean the laser with a q-tip and isopropyl alcohol and dry it with the other end of the q-tip. It doesn't take much for them to not be able to read a disc. If it still doesn't work you will need to replace the laser if you aren't that great at working on electronics or very small things you need to find someone to do it for you.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/benjamin_494963e790f97efb

Try plugging it into the computer with the USB. It's on the charger cord (pulls apart) . The phone will charge from the computer, if it does then it is the wall part that is fried. If not then the Battery. If you have a MINI USB from another product that fits try that one too. I have one from that fits. It's from the Plantrnics, same size. So check any you have laying around.

phone have manufacturing problem of battery or so you have to change your phone brand or model

Did you spill something on it or is food lodged in unit if so take apart clean.
Fresh batteries would be good start.

YOU MUST fix your REMOTE. REPLACE BATTERY OR BUY A NEW ONE! THE KEY IS A LASER TYPE KEY MADE SOLELY FOR YOUR VEHICLE. SORRY BUT THE KEY IF EXCLUSIVE AND EXPENSIVE!
