    Does this seem like a gamma problem to you? Philips 42PFL3512D/12

    Hello!

    I have already fixed some TVs in the past years, but now I am planning to buy another faulty unit for cheap. However, checking the pictures that the seller made, I can't decide if it's a Gamma problem or not.

    I'm open to learn new thingies, but I don't wanna waste too much money if it's not repairable.

    The seller sent me the 3 attached pics.

    What do you think?

    Looks like an AS15F IC issue to me ! That is located on the T-con

      Yes, I have fixed that kinda problems too recently, but this color distortion seemed a bit different from what I saw before. I wasn't sure.

      But if more people agree on the AS15/AS19 chip, I will buy it and give it a try.

          Well.. i have to buy the TV first and wait for it to arrive.
          If I buy it in the first place ofc.

          I'm just not sure if that will be the problem, thats the reason I made this thread.

            Is it worth an expensive transport for a very old tv? Yes it is surely gamma problem, as15 if i remember. I have fixed the as15 on the 37" version. I remeber that was not a good bargain because it had channel memorization problem that needed too much expensive Philips service update, and it had no LCN organization.

              Well, I am not buying it to use it, just to fix and then sell it. It's what I am doing nowadays to gain some extra money and practice before I get a job.

              These kinda TVs in my country are listed (and sold) for ~$100 when working.
              The bad unit is sold for ~$30, and I have an AS15 chip at home.

              So if I can make ~$70 profit, I am more than happy.

              This is the same profit I usually make after fixing then selling LED TVs with bad backlight.

              Anyways, I will most likely buy it, if you all say it seems to be a bad gamma chip, I have too much free time, and every penny profit is good.

                  Oh yes, I forgot to mention, that the shipping is free (counted in the price to be more exact).

                  The other problems can ofc be annoying, I will definitely think about it again tomorrow.

                    I would give it a shot, it looks like typical bad gamma chip, try freeze test as suggested. Philips are good tvs, I have one and it's every bit as good picture as a sony or sammy.
