Re: Help for identify componenti on Samsung Power supply
Looks like a vertical soldered pcb to me. Is there anything on the other side?
Can't be any component since both pads are soldered on one copper plane.
Would make no sense. -
Re: Help for identify componenti on Samsung Power supply
Yes Is vertical, but there isn't anything on the other side.

Re: Help for identify componenti on Samsung Power supply
Could those be big vias to connect the top layer to bottom? Maybe plated vias couldn't handle enough current or it would be impossible/too expensive to make such large plated vias?
That would make sense to me as i can't see any vias on that board.. Or is this a single layer board? I know PSUs are usually single layer.Last edited by KvnTM; 11-09-2019, 05:40 PM.Comment

Re: Help for identify componenti on Samsung Power supply
The board is single layer, no via's. They don't seem to be part of the circuit, so maybe they are used during the manufacturing of the board.Last edited by R_J; 11-09-2019, 06:09 PM.Comment

Re: Help for identify componenti on Samsung Power supply
Ok I'm out of ideas then as to why they would put those in. Increasing BOM cost for no reason?

Post good, clear, straight on, in focus pictures of the board (and the area of the damage) and maybe we can figure out the problem.Comment

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.

This Samsung combined power supply and inverter was replaced a while ago from a Samsung 37inch LE37B530P7W TV. However I would like to repair this one.
I have replaced the Mosfets Q1820 and Q1821 ( FDPF7N50U) which were both blown and the fuse FM802S. The schematic for this power supply that is attached doesn't relate to this power supply as the driving transistors and diodes are D1830, D1831, D1832, D1833, Q1811 & Q1810 are nowhere on the schematic!
Does anyone know what the components for D1830, D1831, D1832, D1833, Q1811 & Q1810 should be? I ask as I did change the Mosfets... -
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... -
