The tv shuts off after 5 sec so I test in the 5 second window?

The pson voltage

Stop that and just list the results as I asked you to - Are you using that ground screw we can see in the pictures for the black prob.
And did you do the first Ohms probes touch meter test.

Pson-0.49-sgnd-0.00-5vsb-0.50-sgnd-0.00-12v-00.2-sgnd-00.0-24v-00.0. Sorry wanted to make sure I was doing right with the pics,yes I'm using the ground sctew

The pink fusable resistor - no continuity,200 ohms 1.

Re: Sanyo dp42848. No picture no sound?has anyone found the problem

Ok what do you think?

Re: Sanyo dp42848. No picture no sound?has anyone found the problem

I probed the pink fusable resistor with the bord still mounted on the tv,should I probe it from the back of the board?

Re: Sanyo dp42848. No picture no sound?has anyone found the problem

I will wait for the next step?

Re: Sanyo dp42848. No picture no sound?has anyone found the problem

Ok what do you think?

I think you should go back and read how I asked you to post the result.
There is nothing worse than being faced with a long line of numbers to decipher.
Oh! Sorry, there is - its a long line of numbers where several are listed
totally incorrectly and some pins are missing.

Pink resistor is that from primary to chasiss? It should normally read open. Please be patient. We are busy. I have a maths test to revise for.

The pink fusable resistor - no continuity,200 ohms 1.

Try it again with meter on 2000 ohms

Re: Sanyo dp42848. No picture no sound?has anyone found the problem

I'm am not being in a hurry..that's why I said I will wait!and I did post the results like you asked,,what did I miss?

Re: Sanyo dp42848. No picture no sound?has anyone found the problem

No I tested continuity from one side of the pink fuse to the other
