    Teac LCD221d TV flickering problem

    Hello: I have one of these Teac 22" tv's that seems to work fine except I don't have the original external power supply, which should be (15v-6A). The only one I have at the time is a (16v-3.7A). Would the difference in available current be the cause of the flickering,? or what. This tv is about 5 years old and user manuals and schematics dont seam to exist, unless i'm looking in the wrong areas? Any help on this model would be appreciated,Thanks

    Regards:Andy

    1. I would suspect the power adapter.

    2. Source of service manual.

      I also suspect the power adaptor. You are drawing way too much current causing the voltage to lower. You may also overheat the power adaptor and cause a fire hazard

        Hi, I found a (16v-4.5A) power supply and this cured the flickering problem, but still gets hot of course, and i wouldn't intend using it on a permanent basis,i'me just trying to sort the thing out. I got it at a salvage auction with no power supply and no remote. That is the other problem,I've used a couple of those cheap programable remotes, but the codes seem to only operate the minimal operations, like on-off,and volume and change stations if you're lucky, so if anyone has advice on this area I would appreciate your advice.
