seemingly 'dead' Humax 9200T?

began to fail about a month ago- refusing to record, no response to remote or facia buttons (altho time etc still displayed.).
reset using on/off treatment.
sat. night wouldn't show the prog it was recording on tv.
sun a.m ok but hadn't recorded anything from 9 p.m.
tried to edit a pre-recorded show but record buttons would not work. so tried turn on/off. total fail. it now will only do the L00 to L90 boot and Duovision logo display, then all it shows are 4 small horizontal lines. no response to facia buttons or remote. help!
{this is my 3rd 9200, 1st one 'died' same way after 8 months
Humax replaced with a recon. job - vibrated and v. noisy - returned for another recon job - the one that just died after 16 months. also have an old Humax F2 Fox-T that is slowly going 'mad'}.
if i can't fix will prob. look for a 2nd hand Topfield.
