Re: KDL-40S4100 lcd help please

You will need to find out how to access the hidden service menu. Each manufactor has their own button combo to get in. I would suggest googling your Panels model number and xxx-xxxxxx how to access the service menu via remote ect.

Re: KDL-40S4100 lcd help please

I let Tom put the numbers in his spread sheet to see what he thinks.

[tom66]

Re: KDL-40S4100 lcd help please

Please recheck #16 & #18 but it doesn't look right to me... so bad t-con IMO.

ok 16= 2.36
but 18 is the same

Re: KDL-40S4100 lcd help please

Is your meter perhaps an autoranging meter?
The curve looks suspicious, especially around #6 to #8, but apart from that, I can't see any major problems.
So it's hard to be sure, I wouldn't expect image to look that bad with the voltages slightly out.

Re: KDL-40S4100 lcd help please

UPDATE. I changed the tcon after having solarized image same thing. So tcon and main have both been changed.. so now what do I need to do to get into the service menu and what do I need to adjust there? Also when I press power it takes almost 60 sec for the picture to show...

[mattstolte]

Re: KDL-40S4100 lcd help please

Can anyone tell me how to access service menu and what to adjust?

Hi.

The new main board is not compatible with the old board ,different firmware.

There are no files available to download for this model.
I have tried 3 different A boards 2 different t-cons .
Go by the serial number of the TV.

[chrismurphy]

Re: KDL-40S4100 lcd help please

Your best option would be to download and install firmware update before going any further

Re: KDL-40S4100 lcd help please

I too had the solarized picture after fixing the "power led goes green, no picture or backlight" problem by replacing the main board in my KDL40S4100, part number 48.71H01.031.

I figured the solarized image problem out by Googling and finally finding shopjimmy's Youtube video on Samsung solarization after main board replacement: the Panel Version that the main board is expecting is different than the panel actually in the TV.

I found another thread somewhere with the Sony service menu code. Using the Sony remote, press in sequence: Power on, wait for TV to come completely on, left, right, muting, center button, muting, menu.

You will see the service menu, and at the bottom there is the critical data you need, namely the Model Name and Panel Version. Make sure you were sold the right board. I was sold a board pulled from Model Name KDL46S4100, which of course is configured to expect a different Panel Version than the Panel Version that is actually in my KDL40S4100 (which is LCD_AU037_1920).

Armed with this knowledge, you can then ask better questions of the sellers when buying the main board.

I'm asking the ebay seller to swap me the correct board since he technically sold me the wrong product.

It is POSSIBLE that a firmware update will reconfigure the main board as the correct Model Name and Panel Version, but I do not know if this is will occur since I cannot actually find the firmware anywhere. Sony's website does not carry it any longer, and after hours of Googling, I have not found anyone sharing it.

I am looking for the firmware file "KDL40S4100_V1.115.zip" specifically named in the software update manual (Google "Servicer Software Update Procedure"). Does anybody have this to share here?

I have this from Sony:

Re: KDL-40S4100 lcd help please

@R_J:

Thank you from both me and all the other KDL40S4100 owners out there who are stranded firmware-wise!

The funny thing is, the seller has agreed to RMA the board, so I won't be attempting the firmware update on this KDL46S4100 board (don't want to risk bricking it). So we won't find out whether the firmware overwrites the configuration's "Model Name" or not--this time. I'll use the firmware on the next board I buy, though, so thanks!

Perhaps someone else who is stuck with a KDL46S4100-configured board and has no option to return it can try flashing it now and seeing if it works...

---

I am not certain about this, but it appears the LCD panel in my KDL40S4100 is a LTY400HA11. At least that's what the sticker says. IF that is true, then that means the KDL46S4100-configured board is expecting to see a LCD_AU037_1920 LCD panel. ShopJimmy's online store seems to support the sticker: his items for the KDL40S4100 are organized by "Panel Sticker Number: LTY400HA11"

Unfortunately, his items for the KDL46S4100 are organized by "Panel Sticker Number: LTY460HB10, LTZ460HB10" so there is no obvious correlation between the sticker number and the "LCD_AU037_1920" reported by the factory service menu.
