The screen goes blank after 2-5 mins. Sound ok.  When restart sometimes comes back on but not everytime. Replaced T-con. Twice for two different boards. no change. Replaced all 1000uf caps on Power supply. Does not go into service menu by info,menu,mute, power... to check eeprom. Any ideas please

Hi A/P,

Note Quuq files indicate chap with the same prob who checked the LDO's and 'Bingo' - was the solution.

Not so sure what LDO is, and natch distrust 'Bingo' - check the file and let us know what it means if it sorts anything  -  Chris.
