RGH issues- booting errors Resolution not supported/pixelated

[addy2011]

Hi,

Wierd issue with my Slim RGH, Had it over a year no problem. Boot times were very good- booted up withing 40secs-60secs.

However last few weeks when booting up somtetimes it can take up to 10-20min , other times it'll boot up quick then go straight off displaying messages such as 'resolution not supported', or sometimes it'll boot up the screen wil get pixelated- the xbox light stays on.

A few times i'll have it booted up and i'll run a game, then 5min into the game screen will go blank but xbox light stays on.

When this happens i just power it off and on untill it starts working again. when it does work it stays on as if nothings wrong with it!. i've had it on 8hours at a time when working fine.

Normally i use it over the weekends only =- i would say probably 16hours a week. except hoildays when it'll be used all through

My gut feeling is telling me maybe the RGH glitch is wearing off? i hope not as i had it done from someone , don't think he is around anymore.

i also thought maybe it was hdmi cable or port but i tested that by swapping them with my other xbox.
My tv is not the culprit as everything else is fine.

has anyone else ever encountered this ? example 1.jpgexample 2jpg.jpg
