Need 4 screws for phillips 42pf9946-12 plasma tv to fit wall bracket

Best way to be sure is call Philips customer service with the model number to get the thread type and length of these--no two sets are the same here---usually most will be available at local hardware stores if Phillips does not sell them(that would be a bit more pricey and take time).

Hi, I've connected a Philips 42PF9946/79 Plasma TV to a Beyonwiz DP-Lite i Digital Set Top Box. The connection is through a HDMI Cable and TV is viewed on the 'HD' channel/mode. Previous to the Beyonwiz...


your concern points to some adjustments of resolution from your set top box, as we all know all TV'S has fixed resolution doesnt matter what brand and the only way you can change that is through your source which in this set up is your Beyonwiz, please consult their manual and see if you can change the resolution in their video set up page.

I have a philips 43'' flat screen tv model number 42PF9945/12. When i switched it on the standby light came on and a clicking noise can be heard but the tv refuses to come off standby. how can i fix this?

Hello, I came across several times in this type of malfunction, stems from primary circuit of the power supply unit. I solved it by replacing the 5W ceramic resistor. In another case I came across electrolytic capacitors that i had to replace in the same circle. I hope it was helpful!

Hi Mikshanks,

I had the same problem with my TV. It was a horizontal problem with different shades of color, and black spots. I replaced my Upper & Lower Y-buffer boards. Your Y-sus board should be okay since it still powers on the screen. You should replace the Y-buffers Upper & Lower, and it should work. I hope this helps.

best regards,

Can't get rid of HD-D in top corner of TV.

Solved it.

I called Philips and after some research (on their part) this was the solution.
  1. Make sure the PS3 is turned off
  2. Turn on the TV and put it onto the HD channel
  3. Hold the power button until you hear the second beep (roughly 5 secs)
  4. This brings up a screen saying 'a new HDMI device has been detected'
  5. Follow the prompts from here

Philips 42pf9946/12

The plasma display screen is made of a matrix of elements connected to cables along the side and top. On your unit, some of these many, tiny connections are making contact intermittantly thus losing the elements in that area. These contacts are held in place with just pressure and if that is disturbed, you lose that line of elements. Try squeezing the cabinet of the TV on the outside at the top in the area of the loss and see if that makes a difference. May have to go inside and see if the contact assembly is disturbed or warped or something.
