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?

I am well known for being an extremely patient person but you are certainly testing me and I do wonder if my time would be better spent elsewhere. This was the second time I have asked to to list the voltages in this manner, a lot of members dont ask twice they move on to another thread.
You said
Pson-0.49-sgnd-0.00-5vsb-0.50-sgnd-0.00-12v-00.2-sgnd-00.0-24v-00.0.

I said: list the results in a column:
pson = -0.49 Wrong? 4.9v?
SGND = -0.00
SGND = Missing
+5VSB= -0.50 Wrong ? 5v?
+5VSB= Missing
SGND= -0.00
SGND= Missing
12V= -00.2 cant guess 0.2 2.0 20.0
12V=Missing
SGND=-00.0
SGND= Missing
24V-00.0
24V Missing

13 pins 13 results
+5vsb = and so on.

Had you done so the results would be a hell of alot easier to read and you may have spotted your listing errors - assuming they are error as that is now what you said many posts ago?

Well in the picture you posted when we said you did not have the meter set at 200vDC what setting did it show.? You have 200, 2k,20k,200k,2M and 200M. Ohms

Anyway I concede that you do not have 24VDC.
However what you need to see is if it is there initially.
You will need three arms for this or someone to help( its easier in the UK as a lot of our wall plugs have switches.)
With it all set up but not plugged in you need to probe the 24v pin and ground and keep it probed while you plug it in and still probing while you switch it on.
This will check if the 24v came on at all then went off. (As it did in that Sanyo thread I asked you to read)
(This could also have been achieved by wiring in the 2x12v bulbs Budm asked you to get.)

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

Ok took my tv to a repair shop..found out it was the power supply,the windings were bad and a couple of caps. The shop even let me solder the caps in.they also told me that i was using my meter the right way..SO THANKS FOR ALL THE HELP..AND TOM IM SORRY I HAD YOU MIXED UP WITH SELLDOOR..AND WHO EVER MADE THE DRAWINGS OF THE CIRCUIT THANKS..NO HARD FEELINGS SELDOOR OR HOW EVER U SAY IT!forgive me of my spelling..

[tom66]

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

The winding tested good. No caps were failed -- at least, not as far as the TV would be concerned.

Very confused right now!

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

Ok again tested circuit t.1 set meter at 200 ohms NOT 200k ohms is 00.9 on 12-13 and 00.9 on 12-14 IS THAT WHAT YOU NEED?

On POST 43 I requested the reading of the windings. And the result was shown above. I made the drawing.

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

It is what it is sorry

[tom66]

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

It is a story, that is what it is. How did you fix the bad windings on the transformer? I guess you would have to unwind it -- good luck!

[budm]

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

Yes, I sure like to know how the winding is fixed or if the board is working now.
