Hi folks,
Set uses single board TP.SIS231.P83. Out of standby the Green Led glows and the backlight fires up giving a dull Blue screen. Set cuts to Red Led S/by then cycles back to Green Led where it has another go at firing up. Eventually, after a variable time (seemingly not temperature dependent) the set fires up and works normally for hours, other times it cuts to S/by within minutes.
Gather it's a common problem with UMC sets, as had two in the past where I replaced Eeproms to no good effect and they ended up on the pile. Gather some folks think it's a M/proc issue but it doesn't seem heat sensitive as I would have thought - Any thoughts ? - Chris.
