I am looking for diode that is in a panasonic power supply. The diode has a number t3d 64.also the part number is st03-82.if one knows where i can get one or replacement for it.also i test it in diode mode in meter no readings both ways.i am not sure if i can test it with out running current through it.

Re: Panasonic power supply
What is the part # of the power board and what model is it frrom? Often you can get schematics for Panasonic boards, we might be able to suggest a replacement.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!
For service manual, schematic, boardview (board view), datasheet, cad - use our search. -

Re: Panasonic power supply
datasheet, I don't think it will, I see this one posted from time to time. catches people out from time to time, probably not at fault.
what's the full story of the TV/PSU?
tom will knowComment

Re: Panasonic power supply
I have a ST03D-140 in a 2010 PSU and in cct I just get constant continuity beep both ways. In my cct it sits across a primary winding so hence my reading.Comment

Re: Panasonic power supply
I know not shorted was not sure if it was open but as big as that diode is i am thinking it might be ok. I did not know if i could read it like regular did. The problem with power supply is i am missing 15v that comes out of mc301.which gives me 10 blink code going to replace tea1610t and caps near it with .1uf 50v see if it will work. Some mentioned that diode possible being bad that is why i was testing it.Comment

Re: Panasonic power supply
I found here: http://www.eevblog.com/forum/chat/whats-the-part-pls/ you can't test this type like a normal diode. But if it reads open circuit both ways (as yours does) it's probably OK.
You could test the zener function of it though and make sure it's breaking down at the right voltage."Tantalum for the brave, Solid Aluminium for the wise, Wet Electrolytic for the adventurous"

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 wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump
One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy... -
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... -
I did not have any 27uf @ 50 volt capacitors but one nice thing is that it has enough room for two capacitors in parallel a 22uf and a 4.7uf @ 50 volts 22 plus 4.7 equals 26.7uf which so very close to 27uf I will show some pictures of it sometime tomorrow
This is one of the shit est boards I seen in a very long time and it was the daughter board the traces just lifting off the board I had to use the capacitor leads to repair the the traces and the main board is not any better because I had to repair several traces for the daughter board to the main board
After all of... -
I was working on this CNC machine today found no keyboard functioning no control relay powering on
The screen powered on and was giving an operation error but the manual was not very clear about what the error exactly was but with a little bit of troubleshooting and finding out that the control relays not powering on and no keyboard functions we narrowed down to this one switching power supply which of course does not have any indicator LED light they are on the keyboard interface/relay controller board
Found shorted diodes on main controller relays there are 3 of them that...
