JVC LT-32TW51J / 17IPS19-5 - Four or Two UF5404?

[PMcFishy]

I am in the process of changing the diodes on the 17IPS19-5 PSU.

It is marked 17IPS19-5 V.1 061112

But I cannot help notice that I am seeing some boards marked as above with just TWO UF5404 and not FOUR UF5404 as per the board I am working on!

Please see second image - which is a board for sale from spare parts site.

I have also seen just 2 diodes on a board in a super helpful YouTube video from forum member @ReeceyBurger123

Any reason my board has 4 diodes and others have 2?

Many, many thanks in advance

4 diodes: higher diagonal, higher consumption. Or diodes of lower current: 4, higher current: 2.
