Hitachi L42VC04U H Stuck in Stand by

[zoz]

Hi everyone,         
just joined your site and hope your can help a newbie out here....

I have a Hitachi L42VC04U H that purchased at a prety cheap price as it only came on for 20 mins then the display would go multi coloured.
problem seemed to be dodgy lcd panel tape joints which I seemed to fix.
Set work ok for a while then display became pixelated.
Tried to turn back on the following day and would not come out of stand by.
Fault as follows
Turn power on
Stand by comes on (red led) then off
then blue led flashes very fast then off
and then back to steady red

Any help would be much appriecated

Thanks in advance Zoz
