Facing TV Problems? Ask a TV Technician.
Is the power-light lit as though it is in the ON mode?
If so is there any sound please?
I will need the model number please found on the back of the set thank you
So it goes to green the light there is no sound and no picture if you press the menu button of the sets own remote control does the menu come up please (this check is necessary to rule out any signal issue )
Let me know please
Sorry for delay I have only just got my connection back
You have a problem with one of the boards in the set it could be one of the scan boards the power-board or the mainboard any one of those boards will give you this symptom so we need to make checks with a meter can you use a voltmeter?
No it does not work like that please get the meter first and we move on one stage at a time
Yes there is no other way
Ultimately checks are made a board is decided upon to be replaced the board ordered then fitted in the set
Just to clarify for sure there definitely is no menu displayed when you press the menu button of the sets own remote control?
If so the first checks are the Vs and Va supply voltages on the power-board, these will be labelled on the power-board set in the ON mode red lead to test point black lead to metal chassis meter set to dc
I am sorry I have just been called into work I will open the question to other experts please hold on
