LG 42LH3000 Tcon question

[mattheweveringham]

Hi, i have bleaching (fading to white after a few mins) and from everything I've learned it's likely a t-con as15 chip issue (at least it seems that's what i should replace first)

I was wondering about a section of the model numbers and if anyone has suggestions for a decent supplier, even a decent chinese supplier.

My numbers are as follows.

42T06-C03 - 55.42T06.C16 - T420HW04 V0 CTRL BD

I was wondering how important is the c16 part and what does it mean? I got the impression it might be a software thing as lts of suppliers don't seem to issue that part, especially the chinese manufacturers like taishun on ebay.
Does it matter that much and if so how come lots of manufacturers don't list them? Also, what does the c03 part mean?
Would greatly appreciate any help on this as i don't have the tools to solder a new chip but ensuring i get the right t-con or at least a good one is proving difficult.


Thanks guys.

Are these ok? I know one of the chips is hard to see but i took these a while ago, do you want me to go take some more?

The serial is on the board is 42T06-C03 T420HW04 V0 CTRL BD

serial on label is UT 55.42T06.C16 - 013. Was just wondering about the c16 and the 013.

Re: LG 42LH3000 Tcon question

I guess i managed to actually stump the board. I guess c16 is a revision and not that important and the 013 is just a batch number or something.
Does anybody at least know what other tcons are compatible with an lg42lh3000?

If you are looking for a board replacement I think the 42T06-C03 number is the one to use to make your order.

The part number of this board is shown on the white bar code sticker 5542T06C16 with board type being T420HW04 VO (Sticker part number should match for it to work correctly)Substitute Part(s):
55.42T06.C19 55.42T06.C09 55.42T06.C15 55.42T06.C20 55.42T06.C14 55.42T06.C13 55.42T06.C12 55.42T06.C17

As flocko says.

If you want a cheap fix then replace the AS15 chip. Don't forget to check if it's a F / G chip.

Re: LG 42LH3000 Tcon question

Thank you all. I managed to find a C16 so i got that. Very last question is does anyone know why chinese manufacturers of these boards don't list the C16/C17/C18 etc part?
They all say 42T06-C03 and T420HW04 V0 CTRL BD but never list the C16 or substitute parts. Does anybody know why??

Thanks for the information and i won't bother anyone with anymore questions. I was just curious if one of those chinese boards would work with my TV without any mention of the C16 part. Just seems kind of weird and can't figure out if that stands for something to do with the software like a revision or something.

Cheers guys.

Re: LG 42LH3000 Tcon question

the different C1X number is going to be a version of eeprom on the TCON, it wont hurt anything to put a 16 or whatever of that series in, it will distort the picture if wrong

Re: LG 42LH3000 Tcon question

Thanks guys, i managed to find a part with the correct eeprom number so all is good. At least i know i can potentially try a chinese tcon without having to worry too much about that part.
