Re: Funai lc320em1f
You will need to post more information. Have you looked at the boards for any bad caps or fuses? It sounds like the power supply is sensing a fault and shutting the system down. Can you take a picture of the back of the tv without the cover so that we can see the board layout? -

Check power Mosfet for short.Comment

Re: Funai lc320em1f
See if this service manual is close to what you have:

It is one of those bad designed two-transistor switcher power supply.
Boards are pretty cheap:

Re: Funai lc320em1f
If I can just replace one of the boards for cheap.
Just send me a link, please. Witch board is the problem?.Comment

Re: Funai lc320em1f
It looks to me like PSU and input board is combined and the digital main is a separate board as is the inverter board. So at least 3 different boards that could be bad.
Without pics and some basic info about what voltages you have on the PSU, It will be difficult to narrow down which one is faulty.
There are some video's on utube to help understand basic tests on PSU and the inverter board.
Warning!!!! There can be over 200v on the PSU and 400v or more on inverter when operating. I would advise to be very careful if/when testing.
Edit..budm has a few links in his signature that give good instructions on what to test.Last edited by MagicSmoke; 12-17-2014, 09:38 PM.Comment

Re: Funai lc320em1f
Please look at your boards to see which one that matches the one on shopjimmy link I post in post #4 so I can see which exact boards you have in your TV.Never stop learning

Re: Funai lc320em1f
Funai boards are...FUN? Sorry, bad joke. I have found that most of them as was posted before are mosfets ( black things with 3 legs ). Put your mutimeter on diode and check all the way around for short or open. Also Funais have solder issues. Resolder all the big diodes. Those are the 2 biggest issues and once in a while you will find a bad zener but hope that doesn't happen as they are harder to find. I also had a few mains go on them but not as much as the other things mentioned. Good luck.Comment

Re: Funai lc320em1f
Your PSU and mainboard should have a P/N like this..BA94F0F0102 6_A
or something like it. That is the # to search for.
I found at least 2 on ebay. Here is one... http://www.ebay.com/itm/Emerson-LC32...-/261440550311
These are a pain to fix. I have one here that I have replaced zeners, resistors, diodes and mosfet and it still doesn't output any stable voltages.
When uploading pics you have to wait for it to complete, it is not instant. It takes at least 30-50 seconds for each of my pics to upload.Last edited by MagicSmoke; 01-29-2015, 09:09 PM.Comment

Re: Funai lc320em1f
I have another TV where someone else worked on it and left me a mess. So the Emerson LC320EM1f had missing parts. I can't find what diode goes in location D609. Looking at the schematic it seems it has no value anyway I can't find a value for it. Board number BA94F0F0102 6_A. I even have another board and I removed the diode from it but there is nothing printed on it.
I need help please?

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, everyone!
I have here a Schenker VIA 15 PRO, with this numbers on the board: PF 4NU1F V1.0 and P/N: MBPPF4NU18-F310 .
I took out the memory and the battery and the SSD.
So, in stand-by, only the board, takes 36mA. No power-button pressed at all, I can measure 1.8V, 3.3V, 5V. All coils present voltages except the two power rails for the CPU. The CPU is a AMD Ryzen 5 4600H.
After pressing the power-button, the current raises to 500mA and the two power rails for the CPU show up with 0.8V.
After several seconds, the fans switch-off and the board keeps powered...03-08-2025, 04:45 AM -
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... -
I picked up this Vizio E400i-B2 with no stand-by light and diagnosed it with missing stand-by voltage. I found a Power Supply at ShopJimmy, installed it but it didn't work properly. SJ refunded the transaction and did not ask me to send the board back.
So I took some voltage readings upon the original board. Here's what I found:
Main caps have 169.9v
AC detect voltage is 1.3v
None of the MOSFETS appear to be short.
The opto (IC106) that appears to have something to do with stand-by voltage has 3.0 volts on terminal 1... -
Problem
This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....
