Re: Anyone know what causes this fault?
Would need a bigger picture to be certain, but that looks like a Z-sustain fault. Panel is probably fine.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Anyone know what causes this fault?
Yeah, I fixed exactly the same fault. I replaced the X-main on mine, but I think there is probably a simpler fix. Do you have an oscilloscope available?Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Anyone know what causes this fault?
I don't actually own the tv!
Just got the guy to email me pictures of the fault.
May aswel buy it. Out of interest did you replace the x and buffer? Or just the xComment

Re: Anyone know what causes this fault?
The "X-buffer" is just a piece of connector block, it has no electrical function.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Anyone know what causes this fault?
Well it's fixed.
Turned out to be bad solder on the x-main.
All good.

Hello everyone. 😀
As per thread title, this unit has a serious SMPSU fault. It blows F1001, which is a 10A M205 in the phase from the mains input.
Very first thing I tried, was simply replacing the fuse, but the replacement ceramic fuse blew immediately.
Looking at the schematic for this PSU, I then removed what I thought was the next likely candidate: D1001 - the HV main bridge rectifier.
This isolated the fault(no longer blows the main fuse), but does not point me to the actual fault.
There are no devices that have exploded or otherwise show signs... -
- Prior owner tried a replacement main board. No difference.
- Samsung 2x red blinking standby LED = panel fault
- Jumpered FB_TRDY_1 (pin 1 CN1300 left. main tcon->left side buffer boards) and FB_TRDY_3 (pin 95 CN1301 right. main tcon->right side buffer boards) This allows testing individual T-Con (on main board) connection to panel on this Samsung. Found fault on left side (viewing from rear of TV)
- Each side has 2 buffer boards, disconnected left side flex between 2 buffer boards. Fault is on the left most board.
- Tape masking eventually isolated to CN1300 pin 15 (CKV4_GOA) Display

I have been having a fun time at work with two pieces of equipment that had shorted components or shorted component cables to machine frame
I would check what my multi meter was telling me about how many ohms I getting with the multi meter was telling versus the ESR was telling me about weather or not it really was a short to machine ground or not
One note at first we thought that it might be a bad I/O card or a malfunction PLC including me as well but I thought I would try and see if removing the I/O cables would make a difference or not and this time it did make a difference... -
Hello,
I have a strange fault with a Lenovo ThinkPad E14 G2 (Board No. NM-D011 Rev. 1.0).
The first Problem, which I fixed already, was a dead TPS65944AD (USB Type-C) controller. After I fixed this fault, all functions working fine and the notebook run very well with the charger and battery.
On the next day, I tied to start the notebook with the battery, but nothing happened. I started with the charger and on windows, I saw, that the battery was empty. And this was nearly impossible, because the battery was charged. I disconnected the battery and found out, that the board... -
My multimeter has developed this fault, a few months ago. I tried to fix it, but had no success.
The fault is that on the current ranges it never shows 0. Does not matter if the probes are open or shorted.
As you can see from the pics, the offser is the same (just multiplied for other rages):
-4.9 uA
-0.49 mA
-0.49 A
I don't know what exactlly caused the fault.
The meter had a battery leak before I noticed the fault, but I am not sure if the fault was present before that happened. I just did not noticed. The battery leaked...
