David, I don't think I would be happy with that 'repair' or the call out, it surely will not be a permanent fix, he should at least of investigated the dry joint or loose connection, the $90.00 (£50.3254) call out is perfectly justifiable to cover business running costs, but I would at least want some attempt at effecting a lasting repair, you should have had 30 minutes site time.my television went of, repair man came hit it on the top it worked, $90 call out fee he said before you say any thing its knowing were to hit ?
