Can you access your TV's menu? Also can you at least get Channel 1 on your DTV INPUT to appear on your TV screen?
It's important to set your TV to DTV because Autotuning gets turned off if you are on any of the Video inputs on Samsung TV sets.
Since video inputs do not require the Tuner be turned on, they shut it off and block any setup commands for that tuner.
That's why we first need to access the DTV channels.
Usually, Samsung designs their TVs to always have the DTV input accessible. So if you are locked out of the DTV input.....we may need to unplug the TV's power cord, wait 20 minutes to reset the computer inside the TV set, or we may need to use your TV remote in a last ditch effort to restart your intial setup again.
Also, is there some extra numbers and letters past the LE37R7 on your model sticker?
Let me know those answers, and we should be able to resolve your problem with a little research time.
when switched on channel 1& mono appears. this used to dissapear after 5 seconds. cannot access menu.Only buttons that work are Vol & Power.
Full model number is XXXXX 4bdx. Hope you can help.
You can't use the menu button on the right side of the TV set to get the menu to appear either?
I would definitely unplug the TV's power cord for 10 minutes, then test that again.
have unplugged for 1 hour.tried menu button on tv. still no joy.
Hope this helps.
MODEL: LE37R74BD [R]
MODEL CODE: LE37R74BDX/XEU
TYPE No: BD37EO
Ok, I really appreciate you clarifying that for me.
Let's start gathering information together --
Main board. It controls practically EVERYTHING. Literally. It controls your tuner, your inputs, your menu, your volume, channel and even power control buttons on the TV and the remote.
Logically, if you are stuck on D1, that's Digital channel 1. If you have lost power to the TV set, it can sit there on D1 until you access the MENU, go to the PLUG and PLAY setting and program the TV again.
But since you can't even access the TV menu, we pretty much know that the TV's micro is partially dead.
I try to use the Menu button on the remote and the TV set to see if I can get the MENU to respond, but when both don't work, we have to replace the TV's main board.
Now there's some other things I do before ordering any board for a samsung.
First, Samsung has made ONE MODEL using 1 to 4 different Main boards throughout the manufacturing lifetime of that model. Sometimes it's only 1 board, other times it can have more.
That's why I actually LOOK at the board. Some have a BARCODED sticker on it, others have just a small white sticker with a BN number on it. THAT'S the number I trust the MOST!
Can you remove your TV's back cover (remove the screws holding any of your input connections to the back cover, and around the outer edge, and in the center of the Back cover) and take a look for that barcode sticker and get that BN number to me?
Blimey that was a struggle. Tight screws. Here is info you requested.
Uh oh...you got the TV's tuner number --

Did you see a barcoded sticker on your tuner or on the main board ??
On that 2nd picture on the extreme right side you'll notice the board itself has a CODE number. They sometimes label it PCB number too. Those are the codes we look for if there isn't a barcoded sticker, or a simple white sticker on the board with a BN number on it.
And yes, I have accidently gotten the tuner number when I first started looking for BN numbers on Samsungs. You learn to look for
1] Barcoded sticker first
2] Sticker with BN number next
3] BN number painted on the board, preceded by PBA, Code, or PCB or
4] LJxx-xxxxx number painted on the board lastly.
It's a process/list of numbers that we collect when we are in the customer's home.
I'm really surprised you had TIGHT screws....sure they have a little "pop" to them because they are screwed in fast, which does melt the plastic....but the hard part I run across is that FELT TAPE seals the back of the cover to the front OR there's some Locking Fingers on the back cover that really need to be released with a little JERK of the back cover ! Samsung uses Felt tape, Sony does the fingers.
It's always scary running into those, simply because you think you missed a screw or two. Anyways, I've learned to double check, and apply increasing amounts of force, rather than applying maximum force. I've never had to replace a part that I broke with that procedure.
Right. Sorry about earlier error. Had another look & found 2 barcodes. they are as follows,
Hope this is what your looking for.
BN960305A = BN96-00305A
That's a direct match to your model number.
As you stated - "Blimey that was a struggle".
Approximately 60% of a Technician's time is spent on research and verification of the board number, and if the manufacturer has converted the board to a "universal board" number.
Everything points to the part number below to be a "universal board" number.
However, for verification I have sent an email to the above supplier with your original
SEC S/N:CNO7BN960305ADA90B2E0478 coding on your Barcode. You may have dropped a zero on the BN96 0305A part, I'm not sure 100%. But the other numbers above seem to point to your TV having the 1001 part consistently.
And sometimes we have to do the research pretty intensely before we are satisfied with the results.
As you stated - "Blimey that IS a struggle".
