Hello, I have an Omron M400 (HEM-7134-D), the display doesn't turn on and there is no function. It was briefly supplied with overvoltage of 19 V and I can't find the broken part(s). When connected to 6 V, it seems the mainboard is being supplied with power. I'm not sure if the buttons work correctly, or how they should work. If I test resistance on the top left + bottom left pins, the signal only goes through when the button is pressed. Same for top right + bottom right pins. But if I measure voltage, there's always 0.38 V and when I push the button it drops to 0 V, not sure if I understand this correctly. I was wondering if you had any idea where I need to start looking? Thank you. The push buttons are 6 mm size by the way.
Maaf mau tanya...saya punya tensi digital Omron HEM7130 tp waktu di nyalakan angkanya tidak terlihat dan layarnya hitam setengah itu kenapa ya apa bs d perbaiki...mksh
I have the same model, no display except the year appears on the screen n once i press ‘Start/Stop’ button it disappears. Thereafter nothing works. Batteries are new and even with power same result. I checked your video and looked for the continuity and i hear continuous beep noise. Is this the issue with the switch or something else? How do i know if the switch is shorted or not? Ur help is appreciated. Thanks
My omron m3 shows error code E1 , checked air inlet , cuff and all possible issues no damage whatsoever however I hear a click noise but device does not pump the armcuff ? Any idea what can the cause of damage be ? Kind regards
Air leak must be inside the device. Anyway, not a good idea trying to repair this issue, as it can cause error in readings. Better get a new one. Only minor issues with switches should be repaired, as shown in video. Precision instruments can only be calibrated in their factory.
No. Find the switches that are not working. Then remove them. You need only the power switch to operate this. You can then buy new switches and solder them, if needed.
Switch nallathu pole thonnum. But, disconnect cheythathinu shesham, ON/OFF terminal maathram short cheythu test cheythu nokku. If still not working, then something seriously wrong with the board. Anyway, BP machines adhikam repair cheyyathirikkunnatha nallathu. Switch nte polathe simple problems aanel maathram repair cheytha mathi. If its more then 3 years old, better buy a new one.
@@Robsanko Just remove those buttons using a nail cutter or wire stripper or soldering iron. Then it will work. Whether or not to buy new buttons to solder, it's your choice.
No need to replace the micro switch, just put a drop of WD40 on top and let in soak for an hour or two, good as new afterward, this method works on sticky induction cooker keyboard as well!
Luego también, quitas los cuatro botones superiores. Porque los guiones significan "no hay elementos en la memoria", cuando se presiona el botón de memoria durante algún tiempo.
@@electrotechrepair ok... yo tengo uno que le doy START, y aparecen los digitos como si fuera un juego de rayitas... al menos en tu video quedan fijos esos guiones
@@jorgefbo Hmmm... Luego quita todos los botones excepto el "Inicio" y verifica. Solo necesita el botón "Inicio" para usar esto. Después de eso, puede comprar botones nuevos, si es necesario.
Best quality BP monitor - purchase from Amazon...

Then the date button might be jammed - continuous short. Just remove the date button using a nail clipper or wire cutter. Then try to run.
