Actually its not U8 ic but the flash ic U9. So I am probably going to reprogram it from the 43inch TCON board onto the 49inch board. It's a MXIC 25L8006e which carries the data for the screen etc. -
Good news the TV is all up and running. The 43inch TCON board had to be used to get the TV to display anything (no backlights when using 49inch or any image from the board)!
So clearly the Tcon communicates with the main board. So I would imagine that it is looking for the 43inch information from the TCON board rather than the 49inch information.
I could reprogram the U8 and U9 ic's which contain the relevant information onto the 49inch Tcon however for less than £10 it's not worth doing it. I will see if there any issues with the picture over this week to see if I change just one...Leave a comment:

I should have the boards tomorrow so I will keep you advised on the progress. Thanks for the input

One has the part 6871L-5942A for the 43inch set and the 49inch set has 6871L-6043B. I have looked at the pcb's and no noticeable difference to them both. It may just be worth getting anther 43inch tcon board and trying it as they are cheap.Leave a comment:

Sony KD-43XG8196 and KD-49XG8196 can the same motherboards be used as they use the same TCON pcb and main boards?
I have a Sony KD-49XG8196 that I am hoping a Sony KD-43XG8196 main board will resolve my issues with the TV. The TV's both use the same TCON pcb board a 6870C-0761A and use the same main board model (1-982-626-41). Now will I have to modify the eeprom on the TCON board for the Sony 49inch screen TV to work with the TV as it thinks its a 43inch screen and may not communicate properly with the TCON?
If I do what bits will I have to change in the eeprom? I am guessing the model number of the TCON board?
Thanks in advance for any help in my quest to get this TV operational again. -
Thanks Lotas. I have just opened up the TV and powered it on again to find it's stuck on the Sony Logo so it looks like the emmc has failed on the TV! Which upon reading up about these models seem to regularly fail with these issues! Tried a factory reset but no joy. I suppose two options get a replacement board or try to get the emmc for it and replace it....

Factory reset of a Ferguson LED TV 43inch (manufactured by Cello in the UK)
With TV switched on press SOURCE 2580 in a fast sequence.
This will bring up the factory menu screen
Arrow down to either SHIPPING or RESET ALL - Press OK and the press Right Arrow Key
TV will switch off and back on again. if it does not switch back on just press the power button.
This resolved some issues of the TV not coming out of standby on the TV. The original issue was TV would not come out of standby only resolved by turning power off for a few minutes and turning on...Leave a comment:

Service Manual for Sony KD-49XG8196 please as sets dead!
A friend has dropped round a Sony KD-49XG8196 which shows no signs of life. No standby led so need to check the basics first on this main board and the power board.
I have only found one site that has it a Russian site that i don't have access to
http://televid-sib.ru/index.php?topi...3038#msg263038
chassis is apparently GN5TR 9-888-767-E2
The same manual is used in the following TV models:
KD-43XG8196
KD-49XG8196
KD-55XG8196
KD-65XG8196
Any help with finding the manual would be great.
Thanks in advance -
I thought I was right you misunderstood the flickering of the led pulse with 5 pulses on the standby led. This is not the same as you have found out yourself.
Personally I would have been looking for a 2nd hand board for the TV rather than spending countless hours trying to repair it. I understand the challenge of repairing something but time is an important factor when considering repairs on anything.
You have learnt the hard way and hopefully you will not repeat the experience?...Leave a comment:

Excellent free advice is given here to assist you sorting out your TV if you choose not to take the advice and waste your time trying to read and write a flash ic in circuit then go ahead!
I must say Lotas has been very patient with offering you advice. Myself I read the comments you made not following the advice given and was tempted to tell you, but again I think it would have fallen on deaf ears.
Who knows your reasoning why you went against the advice given.
Anyway I suggest if you wish to get help is that you follow Lotas information provided to you. Failure to do so...Leave a comment:

Looks like you have other issues than the firmware corruption as if you read the first post you will see that the standby led flickers when the remote control is pressed. If that is not the issue then you have incorrectly diagnosed your issue with your TV. As you have ordered the ch341A programmer than you can always try to see if it resolves your issue. I would suggest you read the flash ic first to see if the data is corrupted. Good luck

5 years later from the previous post! It's unlikely you will get an answer. I suggest you create a new post with your issues or start reading through some of the threads to check for yourself where to start checkingLeave a comment:

Do you know what a bios ic looks like? Have you taken out the motherboard from the laptop? If I recall its near the sata connector for the laptop (it might be under a foil screen)....Leave a comment:

The Mosfets were changed a while back from a different supplier. I am just going the check the diodes and transistors this coming week as I will really have to remove them as there are a few components that will affect testing if I don't! Hopefully I will report success later on this coming week!Leave a comment:

Thanks I assume you mean C1890 and the C1891 the 220pf 1KV if they are 1KV I may just uprate them to 2KV as I have some.

Just managed to find an image of the schematic see attached file.
Which turns out D1830, D1831, D1832, D1833 are KDS184 and Q1811 & Q1810 are MMBT2907A...Leave a comment:

Samsung BN44-00262A H37F1-9SS power supply help finding blown value components!
This Samsung combined power supply and inverter was replaced a while ago from a Samsung 37inch LE37B530P7W TV. However I would like to repair this one.
I have replaced the Mosfets Q1820 and Q1821 ( FDPF7N50U) which were both blown and the fuse FM802S. The schematic for this power supply that is attached doesn't relate to this power supply as the driving transistors and diodes are D1830, D1831, D1832, D1833, Q1811 & Q1810 are nowhere on the schematic!
Does anyone know what the components for D1830, D1831, D1832, D1833, Q1811 & Q1810 should be? I ask as I did change the Mosfets... -
Ok just ran Mats on it and found two banks showing errors FBIOB0 and FBIOB1. So I will investigate further. Looks like I will be removing memory and checking the memory controllers as well!Leave a comment:
