All you have to do is to make a very detailed drawing with all the cables and their positions (label them to be sure), touch a metal part on the tv to ground yourself, take them out gently (be very careful not to rip a wire), unscrew the board from the chassis, ground yourself again and install the new one and plug the cables accordingly.

Inverter board is pretty easy to replace. It has 3 connectors. One of them goes into the power supply and the other two go into the panel. Its as simple as unplug them from the old board and plug them into the new board. Only problem is ESD(Electro static discharge). Make sure that you touch Some grounded metal before you start working. That should take care of the ESD. Also make sure you unplug the set from the mains and try not to touch any capacitors. They have residual voltages and will give you a nasty shock if you touch them. As an added safety measure wear Hawai slippers.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced.

My sanyo hdtv shows no pictures when you turn it on (the screen is black) but you can hear the audio. The remote control can change the channels and volume up&down but the picture won't show


Good day!


The problem of your TV could be the inverter board or the cold cathode light is busted.

Follow this instruction on how to fix that problem:

  1. Remove the back cover of your TV.
  2. Look for the Inverter board.
Inverter board looks like this:
nineng_6.jpg

3. Check the input voltage of the inverter board if have 24vdc.Using multimeter (range on DC)
4. If you have 24vdc,check the output voltage of the inverter board it should have 500vdc.
5. If you don't have 500vdc output on the inverter,replace it.
6. If the you have the output voltage on it,the problem could be the busted cold cathode light (C.C.T).Replace it.

I hope this solution will be helpful.Thank you and don't forget to rate my answer.
