It does not have a separate backlight inverter. The main power supply board suppies a dc power for the LED backlights.

Re: Samsung UN32F5500 smart TV no backlight

There is a number but I dont know it is part number. It is D2GE-320SC0-R3[12,12,27].

I tried searching using this number and it brings many russian and chinese pages showing the correct strip.

Re: Samsung UN32F5500 smart TV no backlight

No luck finding these strips neither in eBay, nor in Shopjimmy. Even, I am not finding any cracked screen TVs in ebay with matching LED strips.

Attached are two pics of the main distribution panel and the number on a strip.
There are 5 strips and each strip has 9 LEDs in series....

Hi all,

The backlight of my 1 year old TV (Warranty finished) stopped working. Replaced PS board but that did not help. Opened the LED backlight panel and found 1 strip (out of 5 strips with 9 LEDs on each strip) not working. Because of not having experience, I ended with 2 entire strips burned out.

LED driver output from PS board reading: 160 V, 320 mA

Made custom LED arrangement (36 V and 240 mA) per strip using cheap 4.8 watt/meter led strip. The TV is working for 2 days (not uniform light though) but don't know when it burns again.
