Hi , I`m Jack
Perhaps I can help you with this problem but first a few questions

Ask Your Own TV Question
TV Technician: Jack, Technician replied 2 years ago

What is connected to this tv ?
Cable box,satellite,dvd,games etc. ?

Ask Your Own TV Question
Customer reply replied 2 years ago
just the cable
TV Technician: Jack, Technician replied 2 years ago

Nothing connected to the tv like a cable converter with its own remote ??

Ask Your Own TV Question
Customer reply replied 2 years ago
no
TV Technician: Jack, Technician replied 2 years ago

O.k then you mean basic cable , how many channels do you get ?

Ask Your Own TV Question
TV Technician: Jack, Technician replied 2 years ago

When you say just the cable , what is connected at the other end of that cable ?

An antenna or the cable company ?

Ask Your Own TV Question
Customer reply replied 2 years ago
other tv work s fine it is hooked to cable company
TV Technician: Jack, Technician replied 2 years ago

So you are using the TV's remote to change the channels , how many do you get ?

You get this message on all channels ?

Ask Your Own TV Question
Customer reply replied 2 years ago
message goes out get all channels sound no picture
TV Technician: Jack, Technician replied 2 years ago

How do you mean no picture , a dark screen or is it just blank ?

Does that message re-appear after a while or is it only on one channel ?

Ask Your Own TV Question
Customer reply replied 2 years ago
dark screen just message after you turn it on
TV Technician: Jack, Technician replied 2 years ago

Sorry but if you are connected directly to cable and use the TV's own tuner to receive the channels then this does not make sense and I will opt out

You don`t have to do anything , your question will be reposted for other techs. to see and jump in.

Hi Todd and welcome to JustAnswer,

Thank you for the question and your patience. Should you still need assistance for information purposes only...

Initially, consider an experiment (if have not been done). Power on the TV and set to a program/channel. If at all possible, darken the room where the TV is. Wait for about 5 minutes or more. Soon as "...message goes out get all channels sound no picture...", then shine a flashlight at an angle (not directly) and nearly but not touching the screen where the volume level / menu display is usually seen. Press the VOL UP/DOWN or MENU button and note if a dark/ghostly image of the volume level or MENU could be seen.

Postback results.

The above is a test to determine if it is a backlighting concern.

Still and in most instances, it would be an internal hardware issue or more particularly, possible suspects are:

  • • low or missing secondary power supply DCV (least likely);
  • • inverter faulty (likely);
  • • CCFL failure (cold cathode florescent lamps) (most likely).

All of the above would require that the unit be opened up for visual inspection, voltage/continuity/resistance checks, confirm faults and effect repairs.

Please post back how you would want to approach this and/or should additional information be needed.
