Hi Everyone

I have a LG 50PK550 that has no display, i am wondering what the VS and VA voltages should be off of the power supply

Re: Lg 50pk550

They are indicated on the back of the plasma panel, but in general around 200V for Vs and 60V for Va.

Re: Lg 50pk550

In a dark room, does the panel appear to glow?

Re: Lg 50pk550

OK, do you have any sound when you connect a source and blindly change through inputs?

You can download the manual from LG to find out how the menu works.

Desoldering gun station modified to use a 18 volt @ 20 amp switching power supply

by sam_sam_sam

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...

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?

by Tynan Dill

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.

Assuming...

Modification to a ZD-987 desoldering/soldering station using a external switching power supply

by sam_sam_sam

I have been working on this concept for quite some time now with limited success but recently I found a switching power supply that is setup for the voltage that this soldering station needs to operate at however it also needs part of the secondary circuit from the original switching power because you need several voltage rails

I once tried to get a ZD-915 desoldering station to work on a 18 volt battery power supply but unfortunately things did not go well but I did find a work around but I might try this idea again but going at a little differently more about this another time...

Hi, Can we use SMPS Bench Power Supply for Laptop troubleshooting?

by shamsudeen

Hi all, I just need to know that, can i use SMPS type power supply to test and short circuit detection on a laptop motherboard?
I saw 95% of repair guys are using only Linear bench power supply. linear bench power supply is pricy, thats why i planned to get one SMPS supply.

i know that in linear power supply the noise will be very low comparing to SMPS supply....

Russound CA4 Power Supply Repair

by CMCM

Hello Everybody,

Trying to repair a power supply from a Russound CA4 Multizone Controller (picture attached)

Russound no longer supports it but were kind enough to provide a schematic of the power supply (pdf attached).

The outputs marked 12v and 20v are all measuring only 1v.

The board is clicking, which I think means it is in something called hiccup mode when the flyback transformers switches because of an internal problem or something else on the board Overloading it.

The capacitors physically look clean (no bludgesor leaks) and...
