LED Backlight Help

There are many numbers which can all denote which LEDs bars are used within a set. Manufactures often use multiple part numbers for the same part, often making it difficult to know which parts are compatible.
The easiest way to search for LED service parts is by the manufacturer screen numbers. Alternatively to be 100% sure, most LED strips have a part number printed on the PCB.
Many of the same model numbered sets use more than one type of LED Backlight. This can be used when searching but is not the most efficient way to search.

Please note: Sometimes the holes in the strip may not line up with the locator spigots in the chassis. The LED strips can be stuck over these or if desired knocked flat. This is the case mainly with Chinese made sets.

Identifying parts manufactured by LG

Direct Lit LED Strips
Generally these use a 6916L number printed on the LED Strip PCB. A full array will also have a AGF number, but this number is not visible on the set. 

Edge Lit LED Bars
These are usually attatched to a large metal heatsink. This will have a 6922L number clearly engraved.
Please note most edge lit bars do not some with the heatsink.
They will also carry a 6916L number on the LED Strip PCB but this seems to vary massively with many different numbers used for the same parts. 

Screen numbers.
Located on a white sticker , normally above the main PCB – This will start with LC, NC, HC or T. Screen numbers have many variations so a full screen number is required when ordering. 

Identifying parts manufactured by Samsung

All samsung parts will have a small coloured sticker on the LED Strip PCB.
There within the lines of numbers on the sticker 25521A = BN96-25521A 
Most strips also carry a part number printed on the LED Strip PCB, generally starting with 201, D, S, GJ or JJ. 

Screen numbers
White stickers in the centre or corner of the back of the panel, starting with CY, H, G, or T. 

Identifying parts manufactured by Vestel (Hitachi, Finlux, Toshiba, Luxor, etc.)

Screen numbers
There will be a white sticker somewhere on the back of the panel with a screen number starting with VES. The full screen number is important as there are many variations, for example VES400UNDS screens have 3 variations, VES400UNDS-01, VES400UNDS-2D-N01 and VES400UNDS-2D-N11 which all use different LED strips. 

Direct Lit LED Strip numbers
Vestel often use multiple LED Strip numbers , some of which have no distinct markings or numbers. Best to match model and screen type for guaranteed compatibility.

Edge Lit LED Strip numbers
Attached to metal heatsinks, part numbers for these are scarce and only usually identifiable by screen type. Many vestel models can have both direct lit and edge lit variations, so check the screen number carefully.

Identifying parts manufactured by UMC (Blaupunkt / Cello / Goodmans)

Screen numbers
These are NOT enough to order by. UMC screen numbers only denote which LCD matrix is used, not the LED Backlight module. These are often tricky to identify and the set often needs dismantling beforehand to obtain correct LED strip numbers.

Identifying parts manufactured by Sharp

Screen numbers
Look out for a HVW number located on a white sticker on the back of the chassis. This will guarantee part compatibility. 

Identifying parts manufactured by Hisense

With the back removed, there is a white sticker with a screen number. This will usually start with HD or HE. 

Identifying parts manufactured by Polaroid (Chinese build)

Look for a white sticker with a screen number. starting with K . 

Identifying parts manufactured by Philips

Screen Numbers
Screen numbers will start with TPT or TPV. Again the full screen number is important to match but not always enough.

Model numbers
It is also important to match the model number and screen number on the compatibility lists.

LED Strip PCB numbers are not so important with Philips as many variations of compatible parts and strip numbers are used with only one replacement type available.
