Re: Dead Hello Kitty Karaoke Sanrio machine
Ok - On the little board your holding what is on the other side of it - picture?
Looks like the power in socket and battery connector on one half - what is on the other? Which is the main on/off switch

Re: Dead Hello Kitty Karaoke Sanrio machine
i am enclosing a picture to help explain what i measured.........and what i thought you were asking me to measure.......
With the batteries "in" and outputting 9.5VDC......i made the followingmeasurements (see enclosed pic):
I measured DC voltage between
Pins 1 and 2: Measured 0V
Pins 3 and 4: Measured 0V
Pins 5 and 6: Measured 0V
Pins 6 and 7: Measured 0V
i have not measured the diodes yet.........i will do that next. Question on measuring the diodes.......i assume i make the measurement with the batteries in place......do i just make a "resistance" measurement across each diode......should both diodes be on and thus low resistance............let me know
also, if there is another measurement you would like let me knowAttached FilesLeave a comment:

Re: Dead Hello Kitty Karaoke Sanrio machine
check those diodes and see if there open.Leave a comment:

Re: Dead Hello Kitty Karaoke Sanrio machine
OK -so what voltage have you got on the red and black socket on the big board.
What have you got on the red black and white? is that the lead from the switch?Leave a comment:

Re: Dead Hello Kitty Karaoke Sanrio machine
hi,
yes there are 6 "C" batteries.
I am holding the pcb board where the power comes-into.......i can take more pictures of this if you wish
i measure 9.5V DC on the board where it comes in......but then i lose it........
i tried the switch and i think its ok......i will try and take pictures of it and how i meausred it.Leave a comment:

Re: Dead Hello Kitty Karaoke Sanrio machine
Seem fairly simple I would suggest you fix it.Leave a comment:

Re: Dead Hello Kitty Karaoke Sanrio machine
9.5v how many batteries? 6?
What is that part you are holding?
Is the 9.5 measured where it goes on to the board?
Tried the on off switch? Ohm it - see if it works
Bigger picture of the board?Leave a comment:

Dead Hello Kitty Karaoke Sanrio machine
Hi, My daughters Hello Kitty Karaoke (Made by i think Sanrio) machine no longer works. I cant find the AC adapter that goes with the machine but it does accept batteries so i tried that.......output from the batteries is ~ 9.5V DC.
I put the batteries in and ......nothing...........i am enclosing pics of where the batteries go to..............any suggestions or just throw this in the trash..........i thought that since it appeared dead that i might be able to fix it........and besides is like $70 for a new one.Attached Files -

Hi guys,
I have a dead coffee machine, and it seems that the culprit (no 1, at least) is a dead trafo - primary coil seems to be blown open (type shown on the picture below).
Now, I'm unable to find direct replacement anywhere on ebay or aliexpress, and all similar that I' was able to find are rated too low (<1A).
If someone knows a shop to buy replacement (EU/CH), that would of course be my 1st option.
My other ideas:
- to buy 220/20Vac trafo with 30VA, and to "manually" create secondary 12V output just via resistor
- to buy... -
Hello, all.
Cyberpower Battery Backup Unit.
I bought two new ML18-12 batteries through Amazon (They have already refunded my money for the two batteries as we thought the batteries might have been bad.)
When I got them in, they were not fully charged. I connected them to the UPS and waited 24 hours before connecting any networking equipment.
In parallel, they read 24v, but within 24 hours, the meter on the front of the unit dropped from 4 to 3 bars on the battery charge indicator.
Checking the voltage, it was down to 22v.
I quickly removed everything... -

Hi good folks;hope you all had a great new year entrance;afamily member asked me to look at their wash machine Maytag MVWC465HW that is dead no leds turn on , i already took out main board but it's hard to troubleshoot due to the amount of wax covering all the board both sides,all fuses to the rectifier and filtering are good, tried to order it but no boards available and cost more than a new wash machine,so i'm trying to repair it at component level,i would appreciate if you could lid me the way any tip that will help me to fix the main board,there is no parts available for this mod# so it seems,power... -
OK, this is a long shot. I got this sewing machine cheap because it's end of line, ex-display, and had no pedal. The genuine pedal costs £60, while Ebay knock-offs go for around £15. So I went for the knock-off, it doesn't work, and I'm not sure whether it's the pedal or the sewing machine that has the problem.
Now this is an electronic machine, unlike the old fashioned sort where the pedal was a big resistor in series with the power to the motor. Here, the pedal is just (I think) a variable resistor fed with a 5 volt supply, and limited to a current of 5 milliamps. Assuming that...
