My Sharp XE-102 isn't turning on, tested the fuses and they're fine, but found the wire from transformer to board had fallen off. Put it back but it's still showing no sign of turning on

    Transformer is working and is before the rectifier, so the output is AC

Sharp XE-A102 Till. Am trying to set department 8 as a refund department for my small business but am having no luck as I don't understand what keys I'm supposed to be pressing for the ABCDEFGH entry -...


Hi. No need to with the 102. Sharp created a void mode for removing sales. Just turn the key to void mode (the infinity symbol. I think it is fully counter clockwise). Then ring up the item that you want to refund just like you did in REG mode. then finsh with CASh if you are refunding in cash. This will create a negative sale which refunds that item back into stock. ------------------------------------------------------------------------------------------------------

How to measure Voltage in Transforme for Fitness Treadmill


Transformer Test Procedure:1). Make sure that transformer wire connections (CON1) to the drive board are secured. Turn unit on.2). Put multimeter to the AC voltage setting. Insert meter probes into the transformer primary (red)wires as shown. Normal reading: 110V. This shows that there is power to the transformer.3). Test transformer output by probing on secondary (output) wires: black and black, white and white,orange and orange, yellow and yellow

Transformer Test Results :1). If there is no voltage across the primary (red) wires, inspect F1 fuse on the drive board and power to the drive board. 2). If there is voltage across primary wires but none across secondary wires, the transformer is bad.Replace it.

Transformer Wire Colors Normal Voltage Value:
Red and Red 110 VAC.
Black and Black 11-13 VAC
White and White 11-13 VAC
Orange and Orange 27-29 VAC
Yellow and Yellow 10-12 VAC

My Sharp XE-102 Cash Register seems to be dead. It won't do anything. What should I try first?


Try removing the batteries, then turn key to REG mode. Turn power off at wall for 30 mins, then on again, then put batteries in. If still dead, then main board failure is the most common reason. ------------------------------------------------------------------------------------------------------

Powered Subwoofer repair--- Transformer issues?


Well yes transformers do fail and the transformer does say it has an internal fuse fitted which might have failed. The fuse on the board blowing is an indication of overload. The fact it didn't blow again shows that it is not getting any power or the fault has gone (doubtfull).
I doubt the transformer is a step up. But follow the circuit on the pc board till you come to electroytic capicator. This will have a voltage on it. The power level will be no more and perhaps less than the voltage on the capacitor. Another clue to the power level is if the secondary wires are narrower than those that go to the mains. That will indicate that less voltage comes out.
OK what to do. Well most makers say that the transformer is a safety item so it has to be replaced with the same type or one which is approved by the maker. So you can either contact the maker direct or find a service center, (for the brand) which might order you a replacement, or take the transformer to Radio Shack with details of the model number of the Sub, and see if they can get it for you. While there have a look at the multimeters. You should find one that will help you for all your future needs. I recomend one with a scale (rather than a digital). They are some around for £10 to £20 (I know you live in the USA but you can convert it) that will do what you might need it for.
The first thing to do if you get a meter is check with the ohm setting diodes or bridge rectifiers for shorts. IE: as if you had touch both probes together! Also do the same with any transitors you might find. As this could be the cause of the fuse blowing, and even the transformer's failure.

Blown Transformer heat pump


blown transformers are usually from a low voltage short the first thing i would do is wire a automotive or resetable 3amp fuse in line with the transformer so you dont blow transformer after transformer the wire coming off the transformer that say 24v take that wire a couple of inches down and cut it and install the fuse in series there
24v----------------
24v----------x----------
24v--------{3ampfuse}----------

now you can go through your low voltage wires one by one and test them unhook all the wires to your outdoor condenser at your indoor unit(furnace or airhandler) and try turning it to cool now if you blow the fuse the short is between the tstat and the indoor unit if the fuse is still good leave it on cool and hook up one wire at a time to your outdoor unit starting with R a lot of times your contactor or your defrost board will short out on you also look for pinches in wires wires with cracks in the insulation and wires touching metal this situation can be a real pain sometimes i would recommend calling a hvac company if you start to get stumped
hope this will help you

AC Control Transformer keeps failing.


well it has blown the fuse on the transformer, then you have coil switch bad.It could be the coil on the contath in for cooling.But can check by taking the yellow wire a loose and see if the don't blow. The red wire is one side of the transformer and the com could be any color.But look at the red wire because it is the main wire that travel the voltage throuhg the unit.

D52W20BYX1 CONVERGENCE


Well I found the problem! There were several cold joints on the board under flyback transformer. I touched them up, replaced a fuse link (one of three located next to the transformer) and we're all good to go! I found where several other people experienced the same. http://www.curtpalme.com/forum/viewtopic.php?p=124207

Whirlpool MH6151XHT-1 - No Power - Stumped


First change all the fuse and check whether it works or not, if it does not work than as per your finding the secondary transformer could be the issue, the secondary transformer tap down the voltage fro 230-240/110 to required control board voltage. the best thing if the unit is opened then the right problem can be found but as per your description either fuses are faulty or the secondary transformer.
