Lg 47lw5700 not powering on, red standby light blinks. Removed back panel and tested power supply board.


3.3 is the right reading on the power switch on pin...so the main is telling the power board to turn on like it should be, your power board is bad.

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.

What makes the HISENSE LCD (Model LCD 42W58P1) power supply failed to produce output voltage goes to the main pc board?


Hi,
First of all the power supply makes 'Stand By 5 or 3.5V which goes to main board. When we give power on command to the TV the main board sends 'stand by or Power ON' command to the power board which then makes other necessary voltage for the main board as well as other sections. If the power board does not receive 'Power On' command from main board, it will not produce the necessary voltages to operate the TV set.

My Vizio VW42L will not power on. No backlights, no power from pson pin. has 5v stand by power on power to main board. no 12 or 24 volt power. has a new power board and inverter boards.


The main board is defective the power on command originates from the main board and thats what gives the signal to start powering up the set. Replacing the main board should solve the issue. You can get the main board from www.tvcircuitboards.com

Will not power up. Tested from plug to power board. Power does not leave power board from any terminals.


The power supply board could very well be defective. I would also check the Zsus board and the Xsus boards. If either of these boards fail it could also cause the power supply board to fail.
You can unplug the connectors to the zsus board at the power supply and try to turn the set on. If it does turn on, the power supply board is ok. If not, the power supply is bad. If the power supply board is ok, undo the plug connectors that power the Xsus board and hook up the plug connectors to the Zsus board. Turn the set an and see if it stays on or shuts down. Part numbers should be on the boards. Zenith is really LG Corp. Their customer support number is 1800-243-0000.
Hope this helps,
Steve

Hi i changed colour cartridge tried trial run printer died; changed fuse in plug; still no power any suggestions please


in the printer there is a power supply board.there is a same type of 3amp fuse on the power supply board.if there is any kind of overheating in the power then the fuse in the plug and fuse on the power supply board blows out.in some cases only fuse on power supply board blows out.this fuse is placed on the board for safety reasons.because in the older model printers when this short circuit problem was happening at that time whole board used to blow out.so in the new model of printer a fuse is placed on the board ,so if any overheating or any power outage or any short circuit occurs.the fuse blows out instead of whole power supply board. You just need to replace the fuse on the power supply board by disassembling the printer.the power supply board is the green color square shaped board.its the board to which your power wire of printer is connected. the fuse is available at any local electric hardware shop.its not any special kind of fuse. This will help. Thanks please keep updated. please please do rate the solution positively .thank you for using fixya

Without the correct meters and equipment it can get exspensive replacing boards however it almost has to be located on the power filter or the power board. I would suggest the power board over the power filter.
