budm not forgive what has not been said before ..... to see the PC image on TV Connect the cable ...... .... but until we find and tap the Source button ... .... it was not seen on the screen of the pc tv ...... ....Leave a comment:

Re: Powersupply proble, SAMSUNG LA32R71B
I'll watch the red LED flashes again .... and then disconnect the cable ....... 220V ...... wait a few seconds I plug it back ...... and TV TURN ...... a short time ..... is lit and goes out again and so it alone ....... ..... the red LED blinks ...... spend 1 to 2 minutes or less ...... and ignited before going on ....... ........ hear a little noise and smooth .... .... by any of ..... components and try to hear where it came from exactly the noise but I can not ..... then ....

Re: Powersupply proble, SAMSUNG LA32R71B
Then I set and connect the plate on tv ..... and on for the first time !!! I was amazed ..... yet ...... pissed if it would also .... for making the bridge ..... etc. a fact that may be important and forget me !!! well before mounting the plate .... I was checking the voltage on the pin was larger electrolytic capacitor there ... I do not remember right now ... if you call Cm801 ... uo otherwise. Well I disconnected the 220V ..... and would check between pins ... and pass it discharged by bridging their legs ..... before measuring ohms per...Leave a comment:

Re: Powersupply proble, SAMSUNG LA32R71B
well ... once clean .... I try again with the bridge .... and since no trace of the spark !!! and I think ..... phew !!!! I already screwed up! hahaha. I measurement as well as before the voltage plate ..... always remained as to the primary of TM801S ....... and .... yes !!! there is still voltage !!!Leave a comment:

Re: Powersupply proble, SAMSUNG LA32R71B
already I am thinking the worst! but several times I made the bridge out that little spark that wanted to escape out of the space reserved on the plate for f9222l. then I saw that it was me grasilla plate ..... ... among some contacts that I use for welding or desoldering .... I mean a special stripper for this work. I decided to wipe it well .... and once I came clean to try to bridgeLeave a comment:

Re: Powersupply proble, SAMSUNG LA32R71B
momentary bridge course! then one flasheante light (which had just replaced with a new one ..) saw appear ..... that is a good blue spark ... and continues .... in f9222l pin q wanted to jump 20 to 23 or 19 ... that I do not remember right now ... because I'm not with the tv right now ....)Leave a comment:

Re: Powersupply proble, SAMSUNG LA32R71B
no I could not believe it !!! I was there waiting for me !!! and until then I had not seen !!!
Following this ...... ... I also realized that (some of it I know what you said budm!) .... of course! the source does not output the 12, 13, 5 and 24 volts .... until someone press the power button ...... was when he gave me to make a bridge between st / by pins ( q already had 6V) and pin Pon !!Leave a comment:

Re: Powersupply proble, SAMSUNG LA32R71B
then I realized that there is a pin (a pin of the 5,4V) ... called stby and another called pon. Then I measured the voltage in st / by = 6V !!!!!Leave a comment:

Re: Powersupply proble, SAMSUNG LA32R71B
Hi again budm!
( thanks vinceroger69, my testers always are good );-)
Well, today the tv started!
I tell you...
After I unsolder that I did tell you before....
I test ohms in transformer...and In transistor that I unsolder...and test circuit...
Then I installed these....and tried the board with 220V alone on the table...Leave a comment:

Re: Powersupply proble, SAMSUNG LA32R71B
This afternoon I will unsolder TM801S and I will test it and all again.Leave a comment:

Re: Powersupply proble, SAMSUNG LA32R71B
Now I unsolderd DM853 and DM851.
And. I re-test pins 9 to 16 of TM801S and always results 0 ohms.Leave a comment:

Re: Powersupply proble, SAMSUNG LA32R71B
I detected the following
Testing ohms in TM801S,
Pins 9, 10, 11, 12, 13 , 14, 15, and 16. Always betewen alls test results= 0 ohmsLeave a comment:

Re: Powersupply proble, SAMSUNG LA32R71B
Hello again , from Spain budm.
I tested pin 5,4VDC = 0,55VDC
I´m so sorry.
I continuous with test more thingsLeave a comment:
