Hi all, i am hoping that someone will have the expertise to guide me in the right direction as to what is going on. I have a Teac 51 cm TV (basic CRT), which has begun to output very poor picture quality. Basically, the problem is that dark colours come out WAY TOO DARK, to the point that some scenes (ie night scenes) are unwatchable. the problem also manifests in that faces are unrecogniseable (in most cases). To illustrate the problem, the blue-background the set has to unprogrammed channels (ie. where 'snow' would otherwise be), has at its worst, appeared black. The picture is generally fine for lighter colours, except occasionally they appear too bright- eg. people's faces will apear a bright orange instead of skin colour, or grass is very bright green. This makes for very strange viewing especially when combined with the accentuated dark's described above!! The only way i can watch the TV atm, is to put the brightness up very high, like 90/100. However, i do not really see this as a permanent solution, since it really shouldn't be that high. I am by no means an expert on AV stuff. i bought a surround sound system (kenwood) a few weeks ago, and admittedly, have had 2 100 watt bookshelf side speakers, and a 100 centre speaker quite close to the TV set (ignorance!). The archives suggest that this might cause "deguassing" (?) or "doming", however, the symptoms commonly referred to, dont seem to appear in my case. Usually people complain of coloured patches on the screen, or fixed discolouration. I have neither of these problems, simply that dark colours are way too dark (almost like there is no contrast amongst dark colours). Also, i have tried the suggested remedies, by turning the set off, and removing the speakers- however, the problem remains. Given the above, can anyone think of what might be the problem. I apologize if it is something simple and obvious, but i really just dont know. Thanks, Dave.
