    First. Does anyone know for sure the correct type number for the field
    output chip in an
    Alba TVD 3406/A 14" portable with built in DVD player ? It's a 7 pin TO220
    package, so I'm guessing that it's a TA or TDA something. Unfortunately, the
    side is blown off it, and it doesn't appear to be laying anywhere in the

    Second. Has anyone been having trouble with programmes from Sky Living TV
    recorded on a Sky + box ? Only seems to have been happening over the last
    few days, and only on Living TV channel. There is no problem with the live
    broadcast, only when it has been recorded. Every couple of minutes, there
    will be a brief burst of pixellation, followed by an equally brief freeze
    and jump of between almost nothing and a few seconds of recording. This is
    followed a couple of seconds later by an again brief interuption in the
    sound. It's really annoying to watch. Both LNB inputs are showing good
    signal strength of around 60%, and both show locked transport streams with a
    quality factor of around 80%. Both these figures are absolutely normal.

    I have heard whisperings that there are some recording problems as a result
    of a recent software upgrade, which is of course automatically downloaded by
    the box, but if it is down to this, I wonder if anyone has an explanation as
    to why just one channel should seem to be affected ?

    A travel tv program on the PBS channel was acting similar to that a
    month or so ago.I haven't tuned into that program on the PBS channel
    since then.At first, I thought it was something wrong with my Sony Wega
    Trinitron CRT 27 inch flat screen tv set.

    Trouble is, with everything being locked into software these days, you just
    never know with these obscure problems. Sky do automatic overnight
    'upgrades' (!) to the box's software to both fix problems and add new or
    revised features. Sometimes, I guess that a fix sorts out 20 models and
    screws up two others. Unless you keep an eye on the box software rev number,
    you don't know that a change has occured. Well, be interesting to see if it
    clears up on its own. If there is some genuine fault like the PSU or the HDD
    getting flaky, then I guess I'll know soon enough ... :)

    Could they be playing some kind of 'copyright protected' DVD and
    broadcasting it over that channel?

    please pardon my infinite ignorance, the set-of-things-I-do-not-know is an
    infinite set.

    It was a regular programme. " So You Think You Can Dance", actually.
    Broadcast last night. Recorded on the Sky box's HDD, and watched a couple of
    hours later.

    will need the chassis reference, (vestel 11Akxx? PT92? Beko?... )
    since alba is just the badge put on the front....

    Agreed. A friend of mine who does rather more TV repairs than I do, as I
    limit that work strictly to 'mates', suggested that there would be a chassis
    reference number, probably starting with a "K" somwhere on it, but I'm
    buggered if I can see anything other than the back cover model number. There
    appears to be no stickers or anything on the PCB that I can see. Would a
    photo help you if you are familiar with this tat ? Or is there somewhere
    else I should be looking for any other identifying marks ? Thanks for taking
    the time.
