  1. Model nr is unreadable but someone told me it's a D110 chassis.
    Old, must be about 12 years.
    Set was dead but after replacing a few caps and lopt the green light comes
    on but no picture, adjusting the lopt
    won't make a difference, haven't checked if there's sound.
    According to the owner who's my landlord the picture became gradually darker
    and one morning it didn't came on
    at all anymore.
    I'm sure i tested all caps, there is HV as when i turn the set off a blob
    can be seen on the screen.
    HOT is fine, startup circuit should be good as well as the green light is
    on.
    Further suggestions?

  2. What voltage you get on the filament? And what is the b+ voltage?
     
  3. Haven't checked but the neck is glowing, i remember we had this before and
    it was a chip failing.
    On the board is a TDA8390 and TDA2549
    I have a scrap board and will swap both and see what happens.

  4. Replaced TDA8390 and TDA 2549, now picture but no vertical output.
    I used second hand parts from old chassis, any chance one chip is faulty,
    hence no vert out?

    No, theres no chance that used parts off a scrapped board could ever be
    faulty. Theyre actually guaranteed 100% by the Immunity From Reality
    Fairy.

    It must be a nice tv to spend this long on it.
