Did you checked the panel TCON Vcc. It should be 5V or 12V in generally.
May be it is below its rating (some drop on Vcc)...
Good luck

Thanks dear , let check the voltage if it is not good what to do, is the capacitor on power supply is not good?

 

[emresel]

Check the cap, it may cause...
On the other hand you should check the fuse (or ferrite beads) on Vcc line.
There might be a mosfet to control (enable/disable) power to panel controller board. You can check that mosfet too.

thanks a lot and what will need to do for the ghost picture of this model

 

[emresel]

Did you reconnect the audio cables again and then what happened?
As mister_rf said in manual it says 8 time blinking means change nearly all board (power, speaker and image board)
TCON voltage is carried to TCON board over LVDS cables. Generally first 4-5 wires or last 4-5 wires are TCON voltage, others are just ground connections and digital video wires. You can check the TCON supply over this cable (see pic, which cable i mean). This is just an estimation about the problem, may be you have problem on image board.
Goog luck

Hi;
when i say image board, i mean mother TV board (it is called bg board on manual)
If OSD is ok, then as you said it must be bg board problem.
