As stated, when you power it on, everything works as should, but picture is faded white, then after a couple minutes it works fine, then goes back to faded instantly.. its pretty much instant change back and forth after a couple minutes.. ive narrowed it down to either Tcon or the FRC.. which should I order? ive tested all voltages and they are in spec, but don't have any information on testing the FRC or TCON voltages or outputs.. I don't have a scope..

Re: Samsung LN-T5271F Faded white picture then works fine
Gamma Voltage test points are on the T-CON board.
You should also upload the screen shot of the screen and also the boards and the whole back side of the TV showing all the boards.Never stop learning

Got a case of something new weird at work. There is an old 2nd gen Intel i3 in an old “Pizza box” shell that has a small form factor power supply. Unfortunately I forgot to take pictures and model number off it.
Anyway, I get to work and get to look at this computer. Standby LED on the PSU is on, but the computer won't start. Hmm o.k. take the battery out of the main board try again, nothing.
O.k. then… unplug the power supply from the main board and put in a full size ATX PSU (yeeeesss! Exact that blown Powerman IP that I fixed a while back), plug it in and the old...

I have a customer machine on my bench right now that's stumped all the techs, so I decided to come here for help.
The specs are:
MPG Z590 Gaming Carbon Wi-Fi (MS-7D06)
Intel core i9-10900kf
2x16gb Corsair Vengeance kit
BIOS ver is E7D06IMS.1B0, from 6/12/2023
The machine was brought in because it would not POST after a GPU upgrade from a GTX 1030 to an RTX 3070. The customer also brought in the original GTX 1030, as well as a GTX 1060 that the machine also wouldn't POST with.
I tested the 1060 and 3070 on my bench (ASRock X570 Phantom Gaming... -
I have this TV set that I spent a long time fixing it.
I finally found a shorted SMD capacitor near the plug from the PS at the main board. It was shorting one of the main voltages (can't remember which one)
I removed that capacitor, and as it has another one in parallel, I left it with only one, checked it and it seemed to work fine. The solder near that capacitor was really delicate as I pulled apart one trace so I prefered to not mess much with it after I had to air solder one small thread of copper
I didn't use that TV much at that time. Now that I'm using it,...10-06-2023, 03:00 PM -

Hi There!
I'm trying to help my friend who owns a restaurant be just bought.
He has a very long LED strip running along all the walls and columns. The strip is attached facing down 2in above the floor, using a wall panel that ends in a metal rail that finishes the panel underneath
It's stuck using, I guess, the 2 sided tape that comes with the strip
The issue is that like 1/2 of the full length, including 1/2 one wall, another entire wall, and one column, flickers after 4 or 5 minutes ON. Particularly it flashes staying OFF most of the time and flashing ON for 1 tenth...
