In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

My Samsung TV doesn't show a picture, when there was a picture audio and remote not working. Which boards need replaced?


If there is no audio then most likely your main board. If your red power stand by light blinks less than 3 s then its the M/B. If its more than 3 s then its the P/B.

Small picture size on Zenith 50 inch plasma


you should be able to zoom, and stretch the picture with the remote control. Since you replaced the main board you lost the settings that were in memory. Simply re do them once more.

42 INCH LCD HD BLANK SCREEN ON BOTH SIDE ON ABOUT 20 INCH AVABILITY. HOW DO I FIX IT.


Hello:
First check the aspect ration in the menu, you also have a format button on the remote that does the same function, or your cable remote. If all is ok with remote and menu, then you might considering replacing the main board as the scaleing Chipo may be bad. Check to make sure picture size is set to full and not 4:9.

Flat Screen 42 inch Vizio does not respond to the remote, called Vizio tech told me to take out batteries and push every button, replace batteries and try. Worked for 3 minutes then stopped again,Replaced...


You can use your phone camera to test the remote. Place the remote to the camera and push to see the IR on the camera. If this works for more than 3 minutes then the IR detector or the processor circuit in the main board is faulty.
This means you need to remove the main panel and use a multimeter to test when the remote is used, trace and see if the fault leads further to the processor.

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.

Most of the time it is the Main Board in the TV that the sensor plugs into. They have had many issues with this Board causing this problem. To be sure, you will need to call a professional.

Hdmi port


I have a 50 inch and recently had to have the main board replaced d/t the IR receiver was failing intermittently. Since they replaced the main board, one of the two HDMI is doing the same thing (picture, no sound). When I spoke to service they felt the issue was related to the replacement board and will be replacing. The weird thing is the picture is not quite right + no sound. Usually with HDMI it's either all OK or not OK at all. In any event, my problem seems to be the main board.
