Unlikely. Real Electronics are the official repair outfit for TC gear, same as MarkBass.
These were their charges about 2 years ago.
£35 to diagnose the problem, which you get back if you go ahead. £69 fixed labour, £18 courier fee to send it back + parts + VAT. I am pretty sure they don't repair to component level, so basically board swappers.
When I got the estimate for my MarkBass it was north of £200, so I binned it.
