found the problem i turnt the tv on and once the fault appeard i used a freezer spray on the chips it turnt out to be the main chip . i then put some heat sink paste on it and took a hink sink and fan off a comp graphics card and fixed that to it to help keep it cool but going to get a new board as i know this was only a temp fix ( new board £59.00 )

Sony and HP are enemies nowadays.

If the issue occurs in the safe mode, then I'm suspecting a failure of the LCD backlight. (It warms up and quits) Also see if video stays on using an external monitor. If it does, then the LCD is most likely failing.

If video goes out on an external monitor as well, then the Video card is failing due to overheating. Make sure all vents are free of dust (Clean with canned compressed air) and the all fans are functional (Run the fan test in diagnostics) If fans check up, then video card is failure point. If fans fail diags, replace affected fan 1st

My nephew had exact same problem, I fixed it by changing 8 puffed up capacitors in the power supply. They went out of business because they copied philips tv design and were sued by them.. The model was ltv-2601(canadian model) but all including ltv-2701, used cheap capacitors. Has been good for 4 months now.

Hi.

If the tv set is still under warantee get it sorted before gtee runs out.

The problem is caused by cummunication error between ATV Micom and DTV Micom.

To correct this problem requires going in to service mode to make changes & updating the DTV firmware.

This will need to be done by a proffesional.
