let me start by saying hello im jeff and im near birmingham alabama and im a complete noob at this whole tv repair thing. To make a long story short i got a hold of a lg 42" plasma at a local thift store a few weeks ago that ended up needing caps, i had it fixed in an hr and had less than 30 bucks in it. Well needless to say now im hooked and i dont really know crap but i have a decent multimeter and a soldering gun and im willing to listen and learn
what i have now is a dynex 46 that does nothing but flash the stand by led there is no reaction when i hit the power button sound or visual not even a click caps and glass fuse look good. Judging from the threads on similar models with the same issue it could be almost anything and troubleshooting it is going to be a challenge. With my strange work schedule it may take me a couple of days to reply sometimes..........Ok guys lets get started, what to look at next !!!!!!!!!!!!

Re: dynex dx46l150a11 stand by power only
OK, on the power supply board, there are 3 white connectors with labels for the pins.
Take the DC voltage readings (using chassis as the ground ref. point), when TV is plugged in but the power switch not activated, then with the power switch activated.
Post all the pins labels follow by the voltage readings.Never stop learning

I am still waiting for the reports of all the readings and the labels on each one of those pins on the connectors.OK, on the power supply board, there are 3 white connectors with labels for the pins.

Re: dynex dx46l150a11 stand by power only
You have 3 connectors on the board, what are the reading on the rest. So far I see the inverter board is not getting the BON (Backlights ON), PWM signals from the main board per your readings on post 8.Never stop learning

by PantherDaveHi all!
I'm trying to troubleshoot a Microsoft Surface Pro (5th gen) model 1796 that won't power on. Motherboard model is M1007506-015. My priority is retrieving data, but the SSD is integrated so it looks like if I can't repair it it'll need to go to a data recovery company. I've done a little basic board repair before, but nothing this advanced until now. So please forgive my ignorance in advance. 😅
I found the boardview for this laptop in the forums here, and am able to open it on my PC with FlexBV.

by GLISITHi all,
TL;DR - this laptop is driving me nuts with the oddball power-related behaviors. Appreciate any insight you can provide!

by sam_sam_samI 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... -
