Sorry, but your scanner is about 16 years old, and factory replacement parts are no longer stocked. If you really like this model though, you might check current eBay listings. I noticed three ongoing auctions for functional BC120XLT scanners, with current prices ranging from $11.50 to $29.99. If you could find a new factory board, it would cost you at least that much.

Sounds like The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electro-medical.blogspot.com/
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

How I change the battery and what is the cost of a battery.


If the shaver still works but just will not hold a charge as long as it should, you can fix this by replacing the batteries. If the shaver is dead and will not run and the green charging light no longer illuminates when you plug it in, you will need to change the whole circuit board.
You will find the batteries and the circuit board with batteries at shaveroutlet.com. You can order which you require by viewing the links below

http://shaveroutlet.com/shaver-replacement-parts/shaver-replacement-battery-aa-nimh-p-108.html

http://shaveroutlet.com/shaver-replacement-parts/braun-printed-circuit-board-with-batteries-p-106.html

To open the shaver, you will need to pry out the two round plastic screw covers on the bottom then remove the screws underneath. You can then remove the outer case by sliding it down and off of the shaver bode. Then remover the black plastic cover inside to access the circuit board and batteris.
If replacing the entire circuit board, you will simply lift it out and replace. If just replacing the batteries, it is suggested that you use a modified installation technique. This is to break the tabs off of the old batteries rather than unsoldering them from the circuit board. This allows the old batteries to be removed but leaves the tabs attached to the circuit board. You can then solder the tabs from the new batteries to the old existing tabs

I can not get the power to turn on. I believe it may have corrosion form leaving batteries insdie the flash.


Clean as much corrosion as you can from the contacts. If you've already done so then the corrosion has spread to the wires connected to them and will need to be replaced. This means opening up the unit and unsoldering the old wires between the contacts and the circuit board and replacing them with new ones.

You'll need to take great care as a flash capacitor can store a lethal charge, and you'll also need good soldering skills to both ensure that the new joints are sound and that you don't put too much heat into the circuit board causing damage.

The actual repair though just costs a couple of pieces of wire and a bit of solder, so is very cost effective if you have the tools and skills.

My psp wont turn on nor charge. even when i take out the battery and plug in the AC adapter it wont turn on.


hi, your problem could be one of a couple of things now the first and most likely would be that your charger is no longer working so you need to try another charger or try your charger on someone else psp.

the second problem you could have could be that the charging port has come away from the circuit board and if this is the case then you will need to get a new charging port soldered onto your circuit board, this isnt something you can do yourself.

now the third problem you could have is that a part has over heate on the circuit board causing a bad circuit usually the part that fails is just after the charging port so this would need testing to find out the exact cause.

first thing you should try is putting another battery in and see if it will come on with a new battery or try a friends battery in yours, if it comes on then you know the problem is going to be either the charger or the charging port, if after trying another battery it still dont work then the chances are something has over heated and the circuit board will need testing and parts replaced if needed.
the problem with this is it all depends on how much the cost of repair is going to be because it could cost more than a second hand psp.

you could take it into a a computer shop and get a free quote on the cost of repair.

you need to try the battery first try and find someone else who has got a working psp and try their battery in yours and also try their charger on yours just to find out if the charger id the problem, if you try someone elses charger and it dont charge yours up then the problem is going to be the charging port or parts associated with that.

Ds lite green light flshing pulse sound from speaker


Check if "L2" is in place. Ususally drop from its position in the circuit board near the power switch, is a little black piece with solder in 2 sides. And the symptoms are almost the same as the blown F1 and F2 fuses.

If you opened your DS and didnt found it or wasnt aware and lost it you'll need a parts circuit board to take it from and solder it to your board, as theres no known part specification or schematics for the DS, at least as I know the only way is using a Henry meter to get the L2 value.

And you might have a water damaged board or broken top screen ribbon cable too as for the tick sound from the speaker is new for me.

Plz help


if the charging port in the handset is broke then do as i say below

:
if you are good at opening the handset then open it and just have a check whether the charging port is directly attached to the circuit board or it is separate from it ....

if it is separate from the circuit board then you need to buy a new charging port which is compatible to your handset & you can replace it easily ....you will get the spare parts in the shops ...

if the charging port is attached to the board then you need to contact the technician ..
he will replace the port or he will make an alternate arrangement(if the spare part of the port is not available)....

you can only replace the port if you are good technically ...
what you must do is first you must remove the solder from the board of the port then remove then replace the new one then solder it correctly at the points where the solder is needed with the board ...

to do this you must be highly aware of the servicing ... if you are not or if you are less aware then dont try this any single mistake may spoil the board ...
so then it is better to contact the technician ....

any way it is not so much costly it is just a matter of some bucks so you can just contact the technician if you have no idea about opening the handset & servicing it.....

any doubts you can reply me
i am always here to assist you
thank you
bye
please rate my solution as per your satisfaction

How to replace batteries on CMM1000 (diagram?)


I have a CMM1000 which needs new batteries. I have pretty much figured out how to replace them, but I haven't found replacements yet. Please let me know where you found them! You need to remove the (black) top cover - there are 6 screws involved. 2 screws are in recesses toward the front on top. You will probably need to remove debris to access these. They are Torx type, but if you don't have Torx bits, they have a slot which works with a flat head screwdriver if you're careful.  The next 2 screws are toward the back down at either side. These are also the Torx type and they have star washers. The last 2 screws are up in the charging area. They are regular phillips and they attach to the circuit board. With all screws removed the top cover will come free. Be gentle though - there are wires from the charging meter that are still attached. You have to maneuver the cover over the height adjustment handle, then flip it up to reveal the circuit board. Disconnect the red and black wires from the terminals marked "TB2 Fuel Gauge Red" and "TB3 Fuel Gauge Blk" The top is now free and can be set aside. There is a push-fit block of styrofoam which can be removed and set aside. You should now be able  access the battery terminals which can be removed with a nut driver or socket wrench.  There is a jumper wire also. Make a note of the polarity of all connections. At this point the old batteries should slide out from their styrofoam cradle (I haven't actually tried this yet).  From this point you will reverse the steps to install your new batteries. Hope this helps.
