I own LG CRT TV, model is 21FB5RLX-ZV. After I turn it on picture is OK for a few seconds but then it becomes yellowish. Also sometimes while TV is on colors become normal for some time so I suspect bad solder somewhere.
Yes it is due to dry solder in vedeo driver section(a board fixed to the pict-tube.).
plz change the picture tube base... or u have to look screen settings in lot...i mean adjust...otherwise the chip may be having problem..ok

I already tried to resolder whole board attached to tube but problem remains. There is only one chip there TDA6107AJF/N1. Now I didn't suck away old solder and put new but only heated solder joints until melting point, could that be problem?
Tried resoldering it with new solder, now when I turn TV on colors are OK but now after a few seconds screens first becomes redish then greenish and in the end yellowish and it all happens within few seconds. Is it possible that the chip is damaged?
thx
