OK, check the resistance between #1 and #2 (I do not know if it is fusible resistor or jumper wire).

Re: Sceptre X32
when I have my multimeter set on ohms for resistance my meter beeps as if it has continuity

Re: Sceptre X32
Fuse is OK, could be one of those red poly caps is bad, or the driver IC is not driving the bulbs. My bet would be on the red poly caps.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Sceptre X32
Yes, those two caps are part of the bridge drive circuit for the inverter transformer. If you have the scope, you will need to find out if there is GATE drive signal from T2 or not.Last edited by budm; 04-11-2014, 12:14 PM.Never stop learning

Re: Sceptre X32
This is going to turn into a really fun thread. Yes, I do have a scope, but I have absolutely no idea how to use it, bought an old Heathkit tube scope from a guy on craigslist, it's been sitting on my bench, but I dont even have a probe for it, let along know what knob to turn and make stuff happen. Can we go down this road, or am I asking too much? I can provide pics on the scope.
Thanks to all, this is getting fun....for me at least

Re: Sceptre X32
before I do that, should I take both of the red caps out of circuit and test them with my esr meter? or are they different that I cant test? I have only tested electrolytic capacitors up to this point with my esr meter.Comment

Re: Sceptre X32
You are going to have isolation transformer to plug this power supply board into for safety, there are other ways to do it but dangerous.Never stop learning

Re: Sceptre X32
An ESR meter can't test those, but if you have an ordinary capacitance meter it probably can.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Sceptre X32
mip320fl-t3 transformer is bad but finding a replacement is almost impossible because they don't sell just the transformer everywhere i looked. just spend the $34 and buy a mip329fl-q3 new power/inverter board. thats from china so it will take a while for shipping. what is the resistance between the 2 output pins of that transformer around 68 ohms? if you do by a new board compare the resistance of the old 1 to the new 1.Comment

Re: Sceptre X32
sorry, I did not know that, is there a reason why?
Please let me know.Comment

Re: Sceptre X32
To test resistance, the multimeter outputs a small voltage into the test leads and across anything you connect it to for measuring. It actually measures the resulting current flow and converts that into Ohms.
If you connect it to a live circuit, high voltages\current could be applied to the meter circuitry, and cause damage."Tantalum for the brave, Solid Aluminium for the wise, Wet Electrolytic for the adventurous"

Re: Sceptre X32
I just ended up buying a new power supply/inverter board on ebay, the mip329fl-q3, which looks like it may have some improvements over the one that failed. FYI.Comment

Re: Sceptre X32
Can mip320fl-q3 be used to replace mip320-2??. They look the same (same PCB). But I do not know the specs.
ThanksComment

Hi everyone,
I am trying to fix a samsung washinmachine power supply main board.
I already replaced it with another one to fix the machine but i want to try understand the issue with the old board.
Therefore i hope to be able to get some help to explain what to check in order to troubleshoot.
The power supply board reference is the following: DC41-00189a
I have followed one thread (https://www.badcaps.net/forum/troubl...ingmachine-rel... -
Hi everyone,
Im looking for some advice regarding my Samsung UE55MU8000 TV with main board model BN94-11606C. The TV suddenly stopped turning on and now shows no signs of life at all not even the standby light at the bottom.
Initially, I suspected an issue with the PSU, so I took it to a repair center. They tested it and confirmed that the PSU works perfectly, even on other TVs. Based on that, I started investigating the main board.
I disconnected the main board from the PSU, and the backlight turned on, which seems to confirm the main board is the issue.... -
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.

Hi, I'm hoping someone can help me with this issue before I give up on this TV.
In short, I replaced the T-CON board due to an error code indicating that was the problem, after which it flashed a green and orange LED meaning software update required. I cannot get the tv to do the required update via USB, so I am stuck.
Here is a rundown of the symptoms and the steps I have taken to troubleshoot:
I inherited the TV with the symptom that it would turn on, then turn off after 5-10 seconds and a red LED flashed 4 or 5 times. Sometimes it would be 4, sometimes...
