Sony KDL-40V3000 - Vertical lines

[gpo23]

Hello,

i order a t-con because i had bad colors on my SONY KDL-40V3000 :




With the new t-con the color are good but there are vertical lines on all the screen :




I've tried the old t-con and it returned to the initial issue (bad colors but no vertical lines)

Is there a way to fix the vertical lines on the new t-con ?

Thank you for your help

Looks like you received a bad tcon, I would send it back for a replacement or refund and make sure the replacement is a match, probably need to match digits 2 thru 5 of the sticker on the tcon.

original tcon is very easy to repair, carry it to a repair center, it could be cheap..

Hello,

For the old t-con, i suspect it is the gamma chip and yes it seems "easy" to replace.

For the t-con with colored vertical lines, do you have any idea concerning the source of this problem ?

yes , i guess the new tcon is not compatible, post a photo of the original one with detail of sticker

For your information, i've read that the color vertical lines can be an issue with the SDRAM. Because i don't have the tools to replaced it, i've ordered a new t-con :

I discussed with the vendor and he will send me a card with a closer reference.

i will keep you updated.

The most possibile explanation is that it was not compatible, i'm not sure about the codes, some photos of the board woulde be better

the easiest way to resolve this issue could be to swap or reprogram the 8pin eeprom bertween the boards you have, so put the one on the original one on to the vertical lines one.. or give the original board to a service shop for a cheap replacement of as-15f chip

I totally agree with that.
See the attached picture of the 8pin eeprom making sure you get pin 1 round the right way when mounting it. Small red dot denotes pin 1.
If you have a clip to read the eeprom then these as I recall will read correctly in circuit.
Good luck
