It's the voltages on all the connector pins that are needed.Leave a comment:

Re: Bush DLED32287HDCNTDFVP led smart tv screen not turning on
1.The fuse is ok.
2. Both of the 400v capacitors look ok and I'm getting 342VLeave a comment:

Re: Bush DLED32287HDCNTDFVP led smart tv screen not turning on
What DC voltage do you have between the two legs of the large 400V capacitor.
Be careful when measuring for you meter probes not to slip.Attached FilesLeave a comment:

on your third picture by the ribbon cable connector there is a fuse do you get voltage too each side of it?Leave a comment:

Re: Bush DLED32287HDCNTDFVP led smart tv screen not turning on
Hi guys,
Sorry for the late reply but i have some health problems and I'm not able to be acctive all the time.
I have tried everything you asked me, i get only standby light and backing light (i have tested it with the led tester)
I have had 2 main boards replacements and it's still the same.
please tell me how to do the testing when you suggest checking something because i'm a newbie and i get confused .
I'll try to attach a picture with every board from the tv but i have a feeling that the led panel is gone .
Thank you all for your patience to try and help me !Attached FilesLeave a comment:

Re: Bush led smart tv screen not turning on
How many volts do you have at Q43?Leave a comment:

Re: Bush led smart tv screen not turning on
How did you verify the backlights work? Does the tv and backlights stay on and and just no picture. Or does it light up and then turn the tv off.
Did you test them with a led tester? If so what was the volts it was reading.Leave a comment:

Re: Bush led smart tv screen not turning on
Check Q43 and Q31 on the mainboard which supplies the panel voltage.Attached FilesLast edited by dick_barton; 05-30-2021, 03:10 PM.Leave a comment:

Re: Bush led smart tv screen not turning on
As i was saying in the description, the backing light is fine , turns on when pushing the power button and i've replaced the main board with a functional one but the result is the same , the panel won't turn on .Attached FilesLast edited by ioanban; 05-30-2021, 02:35 PM.Leave a comment:

Re: Bush led smart tv screen not turning on
Hi,
I didn't see any legend with the voltage to be able to check if the main board is receiving enough voltage.

Re: Bush led smart tv screen not turning on
You need to more accurately describe your symptoms. Do you have standby light and when you press power, it responds and turns on with no video or no backlight. Or does it not respond to the power button? If TV turns on with no backlight, backlights are suspect. If the TV has standby light and doesn't react to power button, then main board is suspect. If TV turns on with no video but has backlight, then tcon is suspect. If you don't have a tcon then panel is suspect.Leave a comment:

Re: Bush led smart tv screen not turning on
Did you check voltages with a multimeter? Is there a legend on the board with pin out of the voltages? Also I’ve never heard of “Bush” so posting pics of all the boards with high res photos would help, if you want help.Leave a comment:

Bush DLED32287HDCNTDFVP led smart tv screen not turning on
Hi,
I have a Bush DLED32287HDCNTDFVP (the one without a T Con board ) with a screen that won't turn on.
I have checked the backing light (it's fine), the main board seems to receive power as well, i have even tried replacing the main board but without any success and checked all the connections .
Does anyone have any idea what might be the problem ?
Thank you,

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... -
Hey guys I've got a MSI GS66 Stealth 11ue-007us Board Number MS-16V41 VER.1 with a broken screen connector on the motherboard.I was wondering how I would go about finding a exact replacement for it.I can't seem to find any schematics that would help me so I'm kinda stumped.I did buy a screen connector that I thought was close enough but it doesn't really invoke much confidence in me that it works perfectly as plugging the screen into sometimes does output a "glitchy" image for just a few seconds.So now I'm kinda in a cross road where I'm pretty sure it could be a faulty screen but I...

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.

Problem
This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached.... -
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...
