Well the latest installment in this sad tale is as follows.
I managed to convince Comet that I had reported the fault on the tv within the first 28 days and they sent out a engineer to inspect the tv.
He accpeted that the tv was just about faulty and he was trying to imply just like the first engineer that all big screen tvs have colour patches on them.
I made it crystal clear that I was not going to part with £700 for a tv that had clear faults and in some ways was worse than the mother in laws £100 beko!!.
The replacement date was set and it turned up today.
Now I have a set that is even worse than the fisrt

.
The replacement set has a very major green/yellow patch on the left side of the screen and a minor one at the top middle.
I have now spoken to Comet and told them that I was not prepared to accept another Thomson as from what I have read on these forums they seem prone to colour staining .
Thankfully the woman at the store was extremely helpfull and all I need to do is have a engineer visit on Saturday morning to confirm that this set is indeed worse and then they have agreed to refund me.
I would welcome any suggestions on what might be a good set to go for once I recieve my refund.
The Thomson was a 100hz set and would have been superb if it wasnt for these staining problems.
Would I be better of going for a 50hz set or sticking with 100hz?.
I only have a budget of approx £800 for the new set.
Thanks
