That is a resistor 0Ω J=(+-)5% 1/4watt, 3216 = size 3.2mm X 1.6mmLast edited by R_J; 01-15-2020, 04:14 PM.Comment

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... -
Fixed a 9 year old UN55JU650 by replacing backlight. Original backlight LED was still working after 27k! hours but terrible picture of course. Few LEDs were out, 5-6 lens fell off (bright white spots) and another few popped off with slightest force. Surviving LEDs were all slightly blue so picture has a blue tint.
This TV runs older Tizen OS (updated to latest version, see pic) and have problems with network (wifi or ethernet) connection. The Tizen UI frequently switch to coax input source while changing content sources. . If no good signal (coax not connected, no prior antenna/cable... -
Hi I'm trying to repair the Samsung lt22b300 power supply. I replaced the srtw6052 chip that was shorted together with the blown fuse and a blown 222 1kv capacitor.
Now if I check the output voltages they all seem ok, but as soon as I connect a load, led or mainboard, all the outputs become oscillating (backlight flashes).
To rule out problems with the LEDs or the main board, I tried to replace the power supply board (PD23A0Q) with a borrowed one from another working TV and everything works regularly.
I checked all the diodes and non-smd capacitors...
