Toshiba 42C3000A screen or tcon

[maxvalutech]

Turn on with blue screen and all looks ok, start DVD player and writing looks ok, play picture and polarisation very evident. Also bring up set menu for a minute or so and faint image retained for a long time. I'm thinking screen had it and that's disregarding green vertical line on far lhs. Thoughts ?

Reset the cables on T-CON first, if still not fixed then check T-CON GAMMA Voltages.
History of this TV?

Thanks budm will do that and I did download the spreadsheet a little while back. Got this and another from chap with youngish family so I think it has had a bit of use alright but no other info except he said had adjusted brightness down and other settings to get a watchable picture -:I have set it back to standard normal. Haven't had back off as yet.

Well I took the back off this very heavy set and must say I haven't seen anything quite like. The tcon must be under the main and the panel that those boards are on - a fair bit of dismantling. Both ribbon cables head that way and I can't see where they actually end up. So if anyone has experience with this would be pleased of confirmation. It is possible to get an almost acceptable picture with adjustments it is just a bit dark.

Have decided to give up on this set. Can't see how I can make any measurements with tcon buried as it is and even to get at it is a pull half the set apart job. It is 10 years old. I have reset picture as best I can and will give it away to someone. Adjusted picture pic shown here.
