Re: samsung lcd, new inverter board, has sound but no picture
from the off position on your meter turn it 3 clicks left...
look on the power supply and you will see 2 fuses... one near the AC main and another one... check the second one with probe to each end... reading?Comment

I'm going to go to bed now, thanks for all your help today newtothis, much appreciated. I'm guessing so far there isn't any fault with this board. Let me know what other components you want me to test. Cheers.Comment

Re: samsung lcd, new inverter board, has sound but no picture
Will be moving onto the CCFL tubes and inverters next.
Won't be on tomorrow as its my daughters first birthday, maybe someone else will chime inComment

Re: samsung lcd, new inverter board, has sound but no picture
Ok, if there was a fault with either of the ccfl tubes or the inverters, are you able to explain why i got backlight, picture and sound with my old board, but not with this board?
Happy birthday to your daughter, have a good one!Comment

Re: samsung lcd, new inverter board, has sound but no picture
Yes it confuses me how that has occurred... hence going through the entire board to check it!
Thanks and will doComment

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

Hi, I have a Samsung UE50TU with:
- sound and backlight, but no picture
- when it arrived, it had a picture for a few seconds
- it keeps rebooting
- without ribbon cable between the two panel boards, it does not reboot but I have no picture
- without cable between mainboard and lcd panel, it does not reboot (but obviously i have no picture)
- when i try a tape fix, its keeps rebooting, unless I tape off pin 1 (the innermost pin). In that case it does not reboot but I have no picture.
- without cable between mainboard and lcd panel and with a jumpered... -
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... -
Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic... -
Hi I am new to this kind of repairs but I want to learn..I have a Samsung UN65JS8500F. the TV used to work and I tried to fix darker areas in the middle only ( img 1,2,3). I thought the led strip were bad..not the case. I did not research in advance what kind and where the LED were located. In this model they are located vertically on right and left side. Took the TV apart and put it back together. Now the tv shows no welcome screen and no sound is available thru the speakers. ..just a black screen..Backlight LED do turn on...also noticed a 5 blink code , not sure if that was there before. I can...
