Re: Trying to fix LCD samsung LE32A330J1 tv, half screen with red tint
Ok I'll have a look into the thing you call "reflowing the ic". No shorts are between legs of chip already checked, there is contact everywhere. I already went through all Gm points and everything seemed fine just that the last one showed 0 voltage which was weird to me and I don't know if it should be like that.Leave a comment:

Cut off the ends, nothing changed. Any other suggestions apart from replacing the chip again?Leave a comment:

Re: Trying to fix LCD samsung tv, half screen with red tint
Can I actually just cut the of the damaged end and it will be ok?
And a side note, how to search for a ribon cabble? Like should I just write the numbers and letters on my ribbon cables or do other parametres need to be specified?Leave a comment:

Re: Trying to fix LCD samsung tv, half screen with red tint
Ok so I looked at the ribbon cabbles more closely and did see something, two of the cables where damaged here are pictures. However I have suspision that I did this while trying to figure out what was wrong because it would be weird to me that because of these two connections half the screen is solarized. The cabble with damage on the right side is on the right side of the tv. I changed the capacitor on this board which one I cannot check right now and will only be able to do it on sunday evening/monday morning. I am starting...Leave a comment:

Before replacement the issue was that the whole screen was solarized, after replacement only half the screen stayed solarized. I bought the chip on ebay from germany to specificly avoid this problem.Leave a comment:

Re: Trying to fix LCD samsung tv, half screen with red tint
Yes a fine idea I thought of myself but could you please tell me how to do it? Or a link to some kind of video? From my understanding I should take the voltage of each cable of the ribbon cable while the tv is turned on? Or am I wrong? And what exacly would tell me that something is missaligned or damaged? No voltage?Leave a comment:

Oh no a faulty capacitor was on a different part of the tv. I only replaced the chip on the tcon. Sorry that i did not make that clear.Leave a comment:

Trying to fix LCD samsung LE32A330J1 tv, half screen with red tint
Hello everyone,
I came here for help with a passion project I've been trying to do. I want to repair a not so new samsung LCD TV.
My journey began with this tv showing distorted colours, they just weren't right, so I did a lot of googling and voltage measuring, to find out that it was probably the doing of a faulty capacitor and the AS15-G chip on my tcon board.
After replacing the two parts with new ones I turn on the tv and half of it is working perfectly and the other half has a red tint and red lines, so continued googling brought me to try and... -
