Since I got my Toshiba 42WH46 RPTV two weeks ago it has been running fine, although the convergence of the red and blue wasn't that great, but I didn't mind as this could be fixed at a later date. However whilst watching TV last night the TV picture went all distorted as if the green convergence has fallen completely out of place! After about 10 or 15 minutes the TV started to come back to normal although the green is worse than it ever was. Have any of you had experience with this? Should this worry me? I am going to carry out the Service Menu convergence tweaks within the next week, but do you think that's all this is convergence issue or could the set be faulty? BTW this is my 4th RPTV in about 3 months, the previous 3 were the 42PW33 but they gave me a completely different problem so I decided to upgrade.
