Hello all!
This is my first post here, so please allow me to briefly introduce myself. My name is René and I live on the Faroe Islands and work as a computer programmer. I'm 26 summers old and I like to fix things myself. That's of course also why I happened to find this forum. :-)
I found this wonderful forum as I was searching the web for information on a specific inverter board, namely a TDK XAD306LR. I got this thread as a result: https://www.badcaps.net/forum/showthread.php?t=12454
I have been studying it, but unfortunately (Or luckily?) it's not the same problem I have. But I'm getting a bit ahead of myself here. First, what monitor are we talking about?
It's a 24.1" Sun monitor. It seems the product number is 365-1434-01. (It's called SunPN) The panel is a samsung LTM240M2 L02 which I found a specification sheet on from Samsung themselves. (I have attached this document)
The symptoms I'm experiencing is that the screen is totally dead. When I flip the switch on the power supply board, nothing happens. The screen power LED doesn't turn on or even blink, and neither does the CCFL lamps it seems. There is no flash or anything on the screen when it's turned on. There is of course a power button on the front of the screen itself, and I've tried pressing it, but nothing happens. The power button on the front of the monitor has a small LED to indicate what state the screen is in: Green = on, orange = standby. But the LED doesn't turn on at all.
I thought it was the power supply board (Which by the way is a FSP100-3P01, see attached photo) so I ordered a new one and replaced it. Unfortunately the screen reacted the exact same way as before. Nothing happens when I flip the switch on the back side of the monitor, and the power button on the front of the screen doesn't do anything either. And the power LED still doesn't turn neither green nor orange.
That was a bit disappointing, but I still hope I can fix it. The next thing I'm planning on doing is testing each CCFL lamp individually with a lamp tester (One of my friends works at a small consumer electronics store where they have a small repair shop. And he offered me to borrow a lamp tester).
But if any of you have any suggestions on other things I can test, I would really like to hear from you.
Also, do you think it sounds plausible that if a lamp was broken, the power LED doesn't turn on at all?
Any suggestions are really appreciated! Thank you!
Best regards
René
