    I have a Toshiba 28 inch TV that is 6 years old. (Model no. 2987DB)

    For last 6 months it has had a loose connection which results in a snowy screen alternating with a perfect picture for about a second each. This can be cured by hitting the scart at the back of the tv a few times until connection holds. this fix can last for 30 seconds or a whole night :smashin: .........however it is taking longer and longer to fix now. :thumbsdow

    :confused: is this something a technician could fix? if so should i contact Toshiba? or an independent? if so where could you find a reliable independent? how much should it cost roughly to take a gamble on it? :confused:

    aware i should have asked these questions 6 months ago! doubt all that hitting has done it any good!! :nono:

    depends on what you mean by hitting the scart, if you mean tapping it with your hand, fixes it for a short time! then why not consider smacking it as hard as you can with a big hammer, this may administer a more permanent repair. or it may render the set totally useless,
    perhaps if you addressed the problem sooner it may not have been so drastic, a new scart lead would of perhaps fixed it permanently never to bother you again, but i would imagine the constant "KNOCKING" has done it no good what so ever, putting unessassary movement/shocks on the solder joints, possibly mishaped some of the terminals,but certainly that fact it has now become worse must demonstrate that the percussion type of repair was indeed unsuitable, ineffective and in fact made it a damn site worse.
    after all scart connections are designed to be made and forgotten about,
    :lesson:

    I would try a new scart firstly.

    Hi
    What are you viewing via this scart conection? Can you use another scart socket or tune the TV via the aerial(rf)

    Yes, quite straightforward. My guess is you have a dry joint within/on the tuner unit.
    When you whack the scart socket area all you are doing is disturbing the tuner as it is mounted adjacent to the scart socket.
    The tuner failing is a common fault on this model.

    No, they won't want to know.

    Where are you located?

    An hours labour if a dry joint on the tuner.
    A bit more expensive if the actual tuner is faulty as it really has to be sent to a company in Manchester for specialist repair.........but still a lot cheaper than a new set and worthwhile doing as long as the crt is still good.

    Jaycee - that sounds sensible. first thing i did when it happened was test the scart and it is (or atleast was before getting so much abuse) fine. and the situation is the same regardless of whcih of the 3 scart sockets it goes in. so your diagnosis looks pretty good.

    was kind of hoping you would say it was beyond repair. would have been gutted to have to buy a new samsung 40 inch lcd !!!!

    One more bit of important info. The prob (alternating between perfect pic and snowy screen) is the same if i am watching TV or a DVD which is connected by a scart.

    I now have 2 guys I have called giving me conflicting opinions. one says i need a new tuner (which seems odd as the DVD probably doesnt need to go through the tuner?) and the other one says there is a loose connection in there somewhere which needs dealt with.

    can anyone clarify??

    Ah well now you should have mentioned this earlier :lesson: ...........it won't be the tuner then as the DVD does not go through the tuner.
    It does look as though you have a dry joint or a hairline crack in the circuit board around that area, so go with the second opinion.
