I have a vintage 2008 Samsung 50” Plasma TV, Model code PN50A550S1FXZA with a power supply part number BN44-00222A. I repaired the power supply board several years ago finding a couple of cold solder joints on the back side of the board and it's worked great up until now. Recently a fried sound occurred with the smell of burnt electronics and the TV shut down. Trying to turn it back on yielded the typical relay clicking with no TV boot up. Upon investigation, removing feeds to the other boards within the TV it was found that disconnecting the logic board from the power supply allowed the... -
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...
