HOW TO INSTALL BACKLIGHT LED DRIVER, GOLD-17ES

[@tv175s3]

My samsung LTM230HL08 panel has a 4 pin connector for the BL. In the datasheet it says is has Backlight: 12S3P WLED, No Driver and the pin layout is: pin1=VIN, pin2=Return1, pin3=Return2, pin4=Return3. I like to replace the controller, but that inverter board looks totally different, no BL-on or ADJ signal? I think it is PWM controller. Do you know a suitable controller?

There should be 1 pin for GND,1 pin for BL-on and 1 for BL-Adj in these 4 pins marked as return, You can with continuity mode on multimeter for GND pin and check one by one other 2 pins by soldering wires and checking results

@@ElectronicSecret Thanks for the reply. I think the Backlight excist of 3 parallel strings of 12 leds in serie (hence the 12Serie 3Parallel, 12S3P ). Each string get voltage through the common VIN on pin1. And each string has his own GND on pin2,3 and 4. So if 'm right, I think I would need a PWM led driver board that can supply power to these 3 strings op 14leds. To supply power on pin 1 and use pin 2-4 as common ground together. I'm don't know in the orignal setup why the driver board use 3 seperate Returns (=Ground?). I had a check with the Ohm-meter on the panel 4pin connector. I don't get any result, all combinations return OL. That is bizar, in my reasoning I would have thought that I would get Ohm result between 1-2, or 1-3, or 1-4, only in 1 direction. Just like I would measure a simple led. But nothing. So I think there is more logic build in the panel besides only the 3 ledstrips. My idea was to use this controller board kit www.aliexpress.com/item/1005001409754867.html where they say it is specific (pré-programmed?) for this type of panel. But the invertor (in fact led driver) doesn't not have the right connectors.

Is it back light driver is the problem when the TV has no picture? but there is sound.

[@ElectronicSecret]

No Most of time it is backlight strips problem, You can check opening the back cover, If you are getting voltage at backlight strip connector then your backlight strips are faulty if not then backlight driver, I have many videos on my channel regarding black screen fix,

[@sevinvenu]

Sir in On/off point how much voltage will be there?

[@ElectronicSecret]

On which point

[@romualdomagsino4497]

How is that cost? 32 inches LED DEVANT back light driver.

[@ElectronicSecret]

Backlight driver cost 3$-5$

[@rockyvlog4087]

Boe panel 32 inch?

How much cost led back light driver price?

[@ElectronicSecret]

300-500Rs

How much On off voltage

[@ElectronicSecret]

12v + Gnd + On/Off Signal
