Re: T-CON Check Spreadsheet

Hi all,

Just to let you know that changing the AS15 fixed the issue and the Sony KDL-37V4000 is working fine again. I measured the voltages of the reference points of the AUOpto T370XW02 VC CTRL BD again after replacing the AS15 for your information, indeed very different values now (see my earlier post for the wrong values):

VGL >> -6,01V
VGHC >> +26,52V
VCOM2 >> +6,53V
AVDD >> +15,61V
VGMA_REF >> +15,33V
REF_1 >> 15,33V
REF_2 >> 14,95V
REF_6...

Re: T-CON Check Spreadsheet

Ok, thanks. Then I will order the AS15 and then try to fix this Tcon board. SMD desoldering and soldering however is totally new for me, so I'll watch youtube videos and try on old computer PCB's first...

Another thing from I learnt from the postings there's a lot of rubbish being sold out there on internet (buying 5 AS15 and only 3 of them are ok...), smells like "component maffia"..

Hi all,

I am new to this forum, it's very interesting and it did help me already a lot to understand things about LCD televisions. Thanks to this forum I suspect T-con board, before I also thought of mainboard..

I am troubleshooting a Sony KDL-37V4000 and it has all the symptoms decribed here in this forum of a faulty T-con board (the AS15 issue). The screen has a white wash and the colors look inverted. All the AV inputs show the same thing and also the menu.

The T-Con board is from AUOpto and it has the AS15....

Hi all,

I'm Marc from the Netherlands. I was not familiar with this forum till I bumbed into some interesting stuff I found on this forum regarding a T-Con board issue that I'm investigating too..

I have a quite broad interest in electronics and have build several things like power supplies and VHF/UHF transmitters and amplifiers in the past. I like the analogue and RF stuff, but would like to learn also other areas of electronics. For some years I was not doing a lot with my hobby but would like...
