I HAVE REPLACED THE POWER BOARD. STILL WONT COME ON. CHECKED THE CIRCUITS. YES POWER IS TO THE BOARD. COULD IT BE THE SIGNAL BOARD?


Hi Pam,
For a TV to come on, the power board has to send 'stand by or SB5V or 3.5V ' to the main board. On your pressing power on button on remote control, the main board sends power on command to the power board which in turn produces all the necessary supplies to run the TV. If the main board does not respond to your TV on command, the TV will not work. So It is not the power board which is responsible for not powering on of a TV every time. A voltage investigation before changing boards is always helpful. I hope it helps.

Replaced Visio TV power supply board TV still won't turn on what else could do this


Hi Charlotte,
I appreciate your DIY approach, but power supply is not responsible for no power on every time. Before replacing any board, use of a multimeter for voltage measurement and a little idea of what the board are doing is necessary. When you switch the TV on the power supply generates 'stand by' 5V or 3.5V and send it to main board. When you press power on button on your remote control or the on TV panel, the main board sends 'power on' command to the power supply which now produces various voltages for the TV to start and work. I hope this helps.
Good Luck

Takes 40 minutes to power on my ln40a550p3fxa


have the same problem it is the main board but no one will post the fix. It can't be that hard to fix! Have a BN94-022079A its similar to your board looks the same and has the same problems. Anyone willing to post the fix for this board. Theres some guy on ebay fixing them for 75 bucks, you send your board in they do the repairs and ship it back

Green light flashes then screen goes off


Disconnect ZSUS board (the one to the right of the power board from the back) from the Y board (the one to the left of the TV from the back) and try to power on again, see if it stays on.

If yes that's the bad board.

If not disconnect the Y board from power and try again.

TV may still shut itself off, but the timing should be different, even if slightly different.

use www.coppelltvrepair.com/newservice to send either or both boards for repair.

As of today (oct 2012) prices are fixed at $100 for ZSUS and $120 for YSUS.

Help new power supply will not power up.


if you had a surge, it could have damaged more than just the power supply. When you plug in the unit, does the power indicator light up??? your main board could also have damage. The main board sends a signal to wake up the power supply thus turning on the TV. If you have to replace the main board as well, it probably won' t be economical to repair the set.

Samsung 32" can not turn on


Dear Bradleyphan,

two weeks ago I fix samsung LCD TV with the same problem and I've managed to fix it.

I will explain how to:


  • Open the case of the LCD
basically in all LCD monitors have two circuit boards (power supply board and system board)
  • After you open you will see the two boards are

  • You see a board that has a socket for the power source. wrote that the board we're looking for (power supply board)
  • Remove all cables connected to the board and take out the board. (get noted before you unplug it)
  • Now you see it components on board, we looking for capacitor.(see picture below)

  • Looking for damaged capacitors, physically you will see a capacitor on the top like a bloated (see picture below)

  • Replace the damaged capacitor with the same value that you can see on the surface of the capacitor. (In this step you need any soldering tool)
My advice: replace capacitors with higher voltage, like 10V replace with 16V or 25V will be fine.
