Re: Samsung le40b750
What do you suggest? Should I test the transformers? What about the CCFL tubes, can i somehow test to see if they work properly?

Re: Samsung le40b750
Thanks Budm for your reply. I have been reading some of your treads to try to get a grasp on diagnosing this.
The PN for the inverter is BN44-00284A, Model H40F2_9HS.
The other board with the external connections is BN41 01167BLeave a comment:

Re: Samsung le40b750
I am assuming that the problem will rise it's head again because i have not used the tv for several months and i have a feeling that the cable disconnection has only momentarily fixed the issue. Can anyone give any advice please?

Re: Samsung le40b750
So i have reconnected the cable, powered the tv back on. Turned on the backlight and everything seems fine?! Is there something wrong with the LEDs?
Help much appreciated. ThanksLeave a comment:

Re: Samsung le40b750
From the photos, i have three boards on the TV. I read on another post that we should check by unplugging the Main board. Which i believe to be the long ribbon connecting the two boards, located on opposite ends of the tv.
Consequently, this made the tv flicker with a blank screen. I could see at the back of the tv, it was trying to 'fire up' the leds.
What does this prove? Any suggestions please, much appreciated.Leave a comment:

Samsung le40b750
Hi All,
My Samsung TV suffers from the flickering issue, which is curtailed if i decrease the backlight and brightness. Otherwise the screen turns black although it is switched on.
I have noticed a few others who have complained about the same problem but I cannot find a definitive solution or diagnosis.
I suppose the next part is to start testing, with a multimeter the separate electronic parts? Which is where i will need your help because i'm a complete novice
Can anyone give any advice on how to fix this please? ... -
Re: Cisco IOS
You probably couldn't do much at all with it, except may be practice with some IOS features. But, you will not know if it works because it needs to be connected to another compatible networking device. However, you could set up GNS3 and use your PC as a virtual router or switch.

You will need a relevant IOS image to install in order for it to work.Re: Cisco IOS<br /> <br /> You pro... works becauseLeave a comment:

Re: New Members - please post your introductions here
Ok, I work in computer networking but enjoy fixing things! At the moment, my TV is broken and i have come here to gain some knowledge and hopefully guidance on how to fix it! My last broken device was the fridge, which was only 16 months old before it broke down. I had to cut the insulation from the back and replace a hidden thermometer! Luckily, with the help of some youtube videos, i fixed it. Ah, the wonder of the internet!Leave a comment:
