Re: fsp 700w blows fuse when powered on
When you replaced the Big cap you did get it the right way round? (It does happen)

Re: fsp 700w blows fuse when powered on
yup i got the polarity right since the test i havent checked/opened again what made that soundComment

Re: fsp 700w blows fuse when powered on
The black wire is ground - can you trace where the green wire goes - perhaps it is damaged or the pin bent?
Have you cleaned out all the dust - is there any brown glue in there -could it have gone conductive?
When you have it on with the light bulb when you switch off are there any hot parts.
Does your meter have temp sensor - only test by touch if you can discharge the big cap.Please upload pictures using attachment function when ask for help on the repair

Re: fsp 700w blows fuse when powered on
dust is cleaned
the glue was non conductive
1.will trace later
2.that i didnt touch when plugged because im afraid maybe it will blow or something thus its producing sound when plugged, btw im using a 100w dim bulb on the test.Comment

Hi, I'll start by saying that I'm not an expert and I've reached a point where I don't know what to try/do anymore...
Starting from the beginning: I opened this subwoofer for the first time with a very strong smell of burnt electrical components, I realize that on the amplifier board there is a hole between V+ OUT and GND about the size of a finger, the damaged components were the shorted mosfets, two damaged zener diodes and two capacitors. I bought everything, I fixed the hole by cutting the pcb and putting a piece of a perforated board.
I had no problems connecting mosfets and capacitors,...08-27-2024, 12:46 PM -
Hello, I disassembled this dead camera, and found this WTF… Two fuses soldered one above the other !
I was pretty sure nobody touched it before, but that can't be from factory. There is flux, and capacitor is probably missing.
The other weird thing : the fuses are « G » fuse : (0.75A – 8V), seems very low. The original fuse should be « O » : (32V 2,5A).
There is « O » mark beside. All fuses have the same mark letter on main board. So, I can deduce it's a « O » fuse.
And this correspond to the issus I saw : when I plug the battery, I measure the voltage dropping... -
I could have sworn I posted about this before, but I can't seem to find the post..
To whit..
I have a 60LN5400 that came in.. Backlights work fine.. No display..
Traced the problem to the TCON board.. Blown fuse..
Replaced the fuse.. Blows again.. Replaced the fuse again... This time it fries the marked part on the Main Video board...
Got a new Main Video Board.. Replaced the fuse on the TCON..
The fuse is fine and the backlights come on fine if I don't have the cellophane connectors from the TCON to the... -
Hi all,
Need some advice to troubleshoot this TV.
PSU blow the main fuse F100, 3.15A.
I replace the fuse with another 3A (but not ceramic) and blows it again after few seconds when i plugged in to the wall, with nothing connected to PSU, just the power cord.
I checked with DMM for dead sorts but didn't found any.
Checked bridge rectifier and seems ok.
Also check main filter cap with transistor / cap / esr tester (the usual cheap transistor testers from ebay) and found ok.
PSU p/n is EAX64405901 (1.6)... -
Hi I wonder if anyone might be able to steer me in the right direction. I have this Samsung UE46ES8000 TV and it went bang during use. The main fuse on the PSU board is open. I've checked every diode/mosfet/transistor I can see and nothing appears to be short to cause the fuse to go. The DC output of the bridge rectifier is not short either. I've seen online that some of these models are known for having their PFC mosfet or other mosfets shorting and blowing the fuse but i'm not seeing that here. If anyone aware of these models having any issues to cause this? I'm reluctant to just replace the...
