Re: 2 Second to black : SAMSUNG P2270HD

It kills your life lol, probably failed transformer. Have you tested the inverter transformer ?

Hi

Our P2270HD has the transformer shown in the picture.

Will exactly the same example as per the above poster be suitable ?

I only ask as although the top rows of characters match, the second rows of characters all differ.

Thanks

Re: 2 Second to black : SAMSUNG P2270HD

Mine second rows differ too.

it 's enough to be TM-09180.

it's the same Power board.. .

and also manufacturers often use same power board at different models.

Re: 2 Second to black : SAMSUNG P2270HD

I've measured the resistances based upon the diagram in your other thread.

I get 1080 ohms for 6 to 8 but open circuit for 2 to 4.

I've ordered the transformer.

Hopefully it won't quickly go the same way as the existing one due to an outstanding issue elsewhere on the board.
