Problem with HP-T4254 Samsung television model

Hi this is a power supply issue. Your power supply is not strong enough to power your tv anymore.

You can get get parts for this tv at www.interliquidparts.com

It sounds like either the X-Main board or the Main Board has failed. I recommend calling 1-800-samsung to find the nearest service center to repair it. You can spend a lot of money replacing parts on a plasma before you find the defective part.

disconnect the hdmi cable from both ends it resets the sound signal!!!

There are reset buttons on the plasma look and find your make sure after you reset your tv that u shut it off for few mins

the capastor on the mains power board are on way out check them look for raised tops ( they look like little bateries with white line) if you are going to replace them yourself take picture so you put back same way

First check to make sure that the audio isn't "Muted". Second, Go into the user menu and check to make sure that the "Melody or Chime " is turned "on". Third, Turn the volume up half way.Fourth, Turn "off" the set. You should hear a "Down" Melody or chime. Next turn "on" the set. If you did hear the Melody when you turn the set "on" or "off" then the audio system in the set is ok. If you did not hear the Melody then the Main bd needs to be replaced. Have a trained Samsung tech repair your set.

Check and replace swollen capacitors in power board.

Okay,i assumed this is what you have:
HD cable box with HDMI cable connection to the Samsung TV.
Listen careful as follow:
First you want to make sure using the same HD comcast box with HDMI connection for our Samsung TV as well as your other TV.Be sure the other TV do received the missing channels from the Samsung TV.You must be SURE you have tested both TVs with the same HDMI cable with the SAME HD cable box.
Now that you have confirmed the both TVS are using the same HD comcast box and the same HDMI cable but the connection that goes to the Samsung TV are missing some channels,at this point,use another HDMI connection behind your Samsung TV and see if you have the same problem.If so,please also try the left side of the HDMI connection and see if you could get the other channels.
Let me know!
