    As a fellow owner I have came to the same conclusion with the fluctuating brightness niggle [I just turn down the brightness], and would add that there is a slim chance that you will find an engineer who knows any more than the bare minimum, about these "magnificent" sets.

    It has taken 3 months for me to get a component input problem resolved on my set, I blame the basic design of the TV rather than the engineers who eventually fixed it.

    Bottom line is I will never buy another RPTV and it will be my last Toshiba TV product. Due to pathetic aftersales service from Toshiba, and the inevitable "washing of hands once sold" attitude of the shop I bought it from.

    In fact while I'm in mid-rant mode, reviewers should take more care when recommending these sets. Before I bought mine, not one review mentioned the brightness, convergence, build quality or poor vertical viewing angles of this product line. They all seemed far to pre-occupied with an improved picture over previous generation RPTV's and dare I say the larger size compared against limited CRT sets, rather than giving consideration to purists like myself who would inevitably tire of the mounting number of "niggly" problems associated with them.

    I have a second engineer coming next week to look at the brightness flucuation I have on my 46who8b.That is - large objects/people moving into/out of picture foreground sometimes causing background or parts of it to slightly lighten or dim. <br />The first so called engineer didn't know too much and said after contacting Toshiba that it was a normal thing for the set. I have read previous threads on it and I've heard there is a fix using the service menu, which is what I'll push for from the next engineer. It happens most on pictures that are 16:9 fullscreen. I see it a little on my Sony CRT but less pronounced on the same material. I'm really beginning to wonder if this is just a fact of life of a big screen RPTV, and also why is it on stuff that isn't fullscreen (i.e different ratios and black bands)that it is much much rarer if at all? Any ideas fellow owners?<br />Thanks <img src="smile.gif" border="0">

    My 40WH08B suffers from this problem too. I have spoken with a (real) Toshiba engineer about this issue. It is a known and accepted problem of RPTVs. Apparently there are ways of improving things...but like everything else...you change one thing, you are likely to affect something else that you weren't bargaining for.

    I've had 4 of the same set now. Each one has had one problem or another. The one I have now still has the fluctuating brightness thing. It even has the fluctuation problem seen with some DVD players (even though it was tweaked in the factory to solve that).

    I have pretty much given up. Toshiba have been very helpful with trying to resolve problems..the main one being the red blotching on the right hand side of the screen. My current set doesn't do that...but it has some other problem with dark lines on the left hand side. I give up. I think RPTVs (at least Tosh ones) are like this. There are some people on this forum who seem to have no problems whatsoever...all I can say is they were very lucky :0)

    cheers<br />Daz

    Thanks Daz<br />If I hear of any magic spells that fixes this stuff (which of course I severely doubt)then I'll let you know. That dark banding on the left hand side I've learnt to live with, and as I say, I most notice brigthness fluctuation on full screen (i.e no ratios using black bands)stuff (and to any others reading that is with contrast , brightness, colour etc set in the lower 40's)<br />It's a good set, in fact when it's good it's great, but I think it suffers from the fact that most of us will probably have a different kind of set in 5 years time (and manufacturers know this)only a few will complain (manufactureres know this) most strangely don't know there's a problem with their sets (Manufacturers know this.....) and I bet it's all plasma soon anyway and RPTV will not be kept developing.<br />PS<br />I'll have Deltas Tv in the meantime cos whatever he will or won't say I say he is blessed

    You are welcome to come see for yourselves! I also had this problem when I bought the tv. Toshiba investigated and came up with new settings which were put into my tv and vured it! I understand more recent models have the new settings but I am sure if you write or email Toshiba at: &gt;BerylO'Callaghan@TOSHIBA-TUK.COM&lt; they will help you. I don't consider myself blessed, I just make a nuisance of myself until things are to my satisfaction!

    Dave - if you were a bit nearer I would come and see. I will try that email address though.<br /> Thing is, my understanding is that my WHO8B is a recent one from the serial number, so their built in fix isn't that great. I still maintain you're blessed, and will be arranging for you to stand next to me on Saturday when I buy a lottery ticket (will a 10% cut be enough?)

    See my separate email.

    Being so well blessed, (ahem!), I think 25% is reasonable.
