    On basis can't do more damage to it put 55" main back in and turned on which gave standby then pressed on and backlight lit up ok but nothing after that as I expected. Then swapped over Eeprom from 42" board and original problem returned. At least this proved Eeprom is the fault.

        maybe worth getting a can of proper freeze spray and trying it on the original eeprom some people have had sucess in slightly heating the eeprom and getting the set to work if the set then starts up ok get a eeprom programmer remove the eeprom freeze the ic whilst in programmer then write too a new ic.

            Yes vinceroger69 and I expect to be in a much larger town within the next week or two so hopefully can get it there. Meanwhile may try to null the Eeprom with vcc to sda connect for 20 seconds. Anyone tried that ??

                UN65TU700DF picture and sound but no backlight. BL tests ok but repl. PSU didnt fix!

                this tv is throwing me for a loop. do samsung tvs no longer have the backlight self test feature built into the power supply?
                i tested the backlight with my LED tester and it lights up both strips. one of them reads 100v and the other reads 63.7v.
                unplugged mainboard from power supply but left backlight plugged in, and then plugged psu wall power in. expected to see backlights light up but see nothing.
                according to how ive diagnosed in the past, this would almost always be a bad power supply. replacement power supply was cheap like 20$ from ebay. but still i get not even...

                Samsung UE60KU6079 backlight okay mainboard responsive, no picture, no sound
                by Ierwin
                Hello everyone,
                Ive got a UE60KU6079 on the workbench that is giving me some headaches trying to troubleshoot.
                The previous owner stated that there had been white dots on the screen which from the description sounded like some lenses fell of the backlight LEDs.
                He had opened the TV from the back, trying to get to the backlight, supposedly gave up, reassebled everything and gave the TV to me.
                I expected the worst like ripped COF cables or a cracked panel but could not find anything like that yet.
                Anyway I still fully expect that there has been something seriously damaged...

                TCL 75S421 has sound but no backlight not even a flash
                by triplefour
                TCL 75S421
                PSU BOARD: 40-L402H8-PWD1CG
                it shows not even a flash of backlight when powering up.
                but the tv appeas to turn on and i can hear the sound of the menus moving and clicking. i can power down the tv with the button.
                testing the backlights with my tester all 4 strings lit up and showed similar voltage drops. around 110 or so.
                unplug mb and leave only psu plugged into backlights (PSU + BL SELF TEST MODE?) does not light the backlights.
                i do see 24v but 0v on PSON and BLON (i didnt write this down tho so cant be sure)
                with mb connected, PSON...

                what i went through dealing with my mobo with dead onboard sound!
                by ChaosLegionnaire
                so i took out one of my spare gigabyte ep35-ds3r mobos from storage for use to do some cpu, ram and video card testing of stuff i bought from ebay and got for free from momaka. he bought 50 e8400 cpus for cheap from ebay some years ago and i decided to help him relieve him of some of his supply since he had waaaay too many!! what did we say about hoarding too much stuff and depriving others of them?! *cough* socialism *cough* lol!

                i had to blow some dust off the board and heatsinks with the datavac as i didnt clean it up before putting it in storage. after finishing...

                Samsung UN60EH6000F Black Screen, Backlight and Sound Good. Power Cycle Returns Picture
                by Mgiffune
                I have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started ‘fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.

                I ordered a supposedly ‘new' Tcon board this time, and                ...
