I have a Triumph Adler branded power supply I have just had to replace the rf filter caps in. I thought it went with a old Triumph Adler laptop I also have but the psu has no voltage stated on it only the amperage, This makes me think that they are not related as the voltage output is 35v which is 15v too high. Will the voltage drop when its plugged into the laptop and put under load or is this power supply for something else?

Re: power supply only marked in amps.
foto's?
does it use a big transformer, or is it a switching type? -

Re: power supply only marked in amps.
Replace the optocoupler and the chip containing the voltage reference. Should be fine then.A working TV? How boring!Originally posted by PeteS in CAComment

Re: power supply only marked in amps.
I am curious as what the DCV rating of those two output filter caps are.Never stop learning

Re: power supply only marked in amps.
not sure but here are some pics of the filter caps I replaced. The small one blew in a cloud of smoke and boy did it smell foul... Still cant get rid of the smell from my workshop now a week later Pooooo..
I replaced they both because its a certain the larger one was probably next to blow.Attached FilesComment

Re: power supply only marked in amps.
Those are are filter EMI filer caps in the primary side, it should have cause the main AC fuse to blow.
But how about the DC filter lytics caps in the cold side, are they rated at 50V or more?Never stop learning

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

I have been working on this concept for quite some time now with limited success but recently I found a switching power supply that is setup for the voltage that this soldering station needs to operate at however it also needs part of the secondary circuit from the original switching power because you need several voltage rails
I once tried to get a ZD-915 desoldering station to work on a 18 volt battery power supply but unfortunately things did not go well but I did find a work around but I might try this idea again but going at a little differently more about this another time... -

Hi all, I just need to know that, can i use SMPS type power supply to test and short circuit detection on a laptop motherboard?
I saw 95% of repair guys are using only Linear bench power supply. linear bench power supply is pricy, thats why i planned to get one SMPS supply.
i know that in linear power supply the noise will be very low comparing to SMPS supply....Today, 07:14 AM -
The sub developed a constant popping every couple seconds from woofer and power LED flickering with nothing but wall AC connected. Connecting an audio cable didn't change anything. It doesn't play but a second or two of audio in between the pops.
Opened it up and discovered the power supply is making a faint clicking or ticking sound.
I measured the amp's output to the woofer and it pulses up to 50mv DC to be driver. The pulses coincide with the power supply ticking/clicking.
I measured the power supply output going to the amp board and it too has this pulsing. Voltage cycles...
