[EARLYBIRD]

  Hi.We have a Vistron LTM-2671E lcd tv,The power supply is a STA200TV-F4. The tv cuts out after 1-2 minutes.
We have changed 6 capacitors (bulging) 3x1000uf 10v and 3x470uf 16v.but still no joy .I believe there is a mod kit but cannot find one on the internet,anyone with any ideas .Thanks Earlybird

We have managed to sort it.The sound output IC was short circuit draging the 12 volts down.The sound was ok till we upgraded the power supply. Nothing seams to be straight forward in this trade anymore.
