Since Monday the 4th of may i have have been called to countless Thomson DTRs with the orange light problem.
The official cure from Thomson is-
Power off for 20 secs,
Hold St by button (on front panel of unit) untill light flashes, release st by at once.
Then press up,down,left,right - in quick succession.
Wait about a minute and switch on.
This has worked well for me.
The red light fault is faulty hard drive and requires replacememt.
As far as i know this was caused by copy protection software uploaded to these machines.
Also, watch out for this one, after switch over the digital multiplexes will change, mostly back to your original grouping, (B) for us here in cental scotland, so no aerial upgrade will now be required!!
