The boards may look the same, but the left one in the tv is the master and gives the signal to the other board.

I have sound no picture on 42LA45H replaced slave and master boards sill no pic

Hi Stacy,
I appreciate your DIY effort. But there are certain conditions for a good Inverter board to work. A good Inverter board will not work if it does not get power from power supply board and certain other commands like "Inverter on" and "brightness control" from the main board. All these things are printed near the connector on the inverter board.

NO master or slave inverters present ??

What is the brand name to your TV? Have you checked whether there is proper voltage comes to back-light inverter boards, from main power supply board? If not check it. It sounds that there is some voltage loss, and the inverter board get voltage from the main board. Check this link. There are voltage charts to some models of television. Pull up older posts there. You haven't provided the brand name to your TV here. In most cases, your TV brand also have been covered. Check the site with patience. If you need any more assistance, be free to do it by comments here by Fixya.

My 42 inch lcd vizio tv flashes like a stobe lite after a minute of powering it on then goes black what can i do

That sounds like an inverter problem. Check the capacitors on the inverter boards. There will be two on each board. The master inverter will be on the far left side, and the slave will be on the far right side. You will have to remove the metal covers over the inverter boards. Should be 4 small phillips head screws. If the capacitors have bulging tops, replace them.

Check the capacitors on the master/slave inverter boards. I just repaired a Vizio VW42LHDTV10A with the same problem. Cost to repair $2. The master and slave inverter boards should be on the far left and far right sides of the TV set. They both have metal covers installed over them so you will have to remove the covers to access them. I'm willing to bet the tops of your capacitors are bulged.

Philips 42PFL7422D/37 42-Inch 1080p LCD HDTV Picture went out but still have sound. Any tips on how to fix it?

If the backlight of the LCD-panel does not function, (no picture) then Master and/or Slave inverter are defective. Inverter boards are screwed to both sides of the LCD display, if they have revision 1.2 boards then they will need replaced with revision 1.3 boards.

Toshiba 47HL167's screen has gone Completely Black

I don't know if you guys are still looking for an answer but turn the TV on where you can here that something is actually playing on the TV then grab a flashlight and turn all the lights off. Get real close to the screen and shine the flashlight on the screen. Can you see something on the screen? If you can then there is a very good chance that one of the inverter boards are out. This could be the slave or the master. For the 47" I actually have the same issue and have ordered the master inverter board. For the 42" I have both the master and the slave board and they are both working. So for the person that has that issue on the 42" TV if you want a board for your TV email me at For the one with the 47" flip a coin and order an inverter board for it either master or slave and try it. To determine which inverter board it is you would have to take the DC voltage across the start and then the end to see if you are getting any power. I hope this helps. By the way inverter boards usually run between 60-120 dollars each and the slave board on both these TV's are easy to install. The master is a little harder due to the power button board is in front of it and has to be removed first. Let me know if this helped.

Backlight Inverter Input Voltage

input voltage like 21.4dc is correct and not sure about master or slave inverter board. You have to check one by one. Here is part store offers cheap prices for boards, please ask required boards.
