Hello everyone!
Tonight I picked up a Samsung UN65NU6900FXZA with a curious issue.
Symptoms:
1) Plug TV in to AC outlet, stand-by light illuminates briefly and goes out.
2) TV does not appear to turn on
3) Backlights do not illuminate, voltages associated with backlights on Power Supply are not present
4) "Power on" terminal on Power Supply has 3.26v
5) "A13V" terminals have 12.9v
6) Stand-by test jumper on Power Supply has 12.9V
7) Optical audio jack on Main Board illuminates
8) With stand-by... -
Hello guys,
I have a Philips 240B7QPJEB. The monitor seems completely dead.
I opened it and measured the voltages of the powersupply. I found that a mosfet was dead and replaced it.
On the connector, that goes to the TCON board, all voltages 15-19V and 5V are present.
The small connector on the left of the PSU has two cables with 18V and all the other have 0.2V. It connects on this small connector on the left ontop of the panel. I guess the backlight? Seens fine I guess.
The weird thing is, that the Power LED is powered over the TCON board.

Hello everyone,
I bought an OLED65C1 refurbished TV back in 2022 from a shop. The TV is awesome, this is my first OLED and I really love it.
However I have an issue with the TV since the end of last year. I noticed when my TV is in Stand-By, sometimes the LED goes off then comes back on. When do so it seem periodical. It only goes away for 1-2 seconds, than comes back on. The TV NEVER turnes off, while it's on, so it's not overheating issue or electrical power issue.
I bought a service remote (MKJ39170828) and checked the menu 3. Power On/Off Status. I took... -
First off,
Happy New Year everyone!
Someone recently asked me to look at their Philips 42pfl4508g/78 TV which had stopped working.
A quick visual check of the PSU revealed a ceramic cap with a hole burnt through it, and that the output voltages were wonky. The 5.2v Standby was only 3.2v. The 24v - 19.1v and the 12v - 11.2v. We found a cheap 'guaranteed working' replacement PSU online, which they bought and installed but it still the TV didn't switch on, and when I went back to test the new PSU board, it showed the same kind of low output voltages.... -
Hello, this might be embarassing since I consider it a dumb question but keeps me kinda stuck sometimes in my journey.
I want to know if there is any post in this forum which explains my questions. A) When, where and how do I know when X voltage line is input or output. Example:
I'm battling with this IC to understand it's voltages. It's from non-turning-on Lenovo Ideapad 3 15iil05 - NM-D461.
I see some lines like +5VL / +5VALW / V9B+ / +3VALW being okay and some others like 1.8VALW / +0.6VS / +2.5V_DDR. I just know that some of them are bad or missing,...
