No image,not Audio. Only power the Stand by Led and blinking. Its no possible power off by way of Sw ON/OFF or the Remote Control. I need to know checking voltage points of power supply connectors..
Try to download its service manual and refer it. Some paid download sites have service manual to this set. No free service manual available now. Try paid downloads.

sounds like either way your power board is bad- do you intend on replacing a component? I would look for Puffy caps- you know- leaking from the top-
SOURCE: Does anyone know which connector to plug into on power supply
Double check all the connections from the AC line and from the power supply to the other circuit boards. The connectors you are mentioning are identical as per the picture below.
If you need a new power supply, you can find one from this link.
Testimonial: "I have a few more questions that I would love to ask Jaime867. He produced a drawing of my circuit board within minutes and was a big help. Thanks"

Problem: Samsung LTM1755B with only a blinking yellow LED when you try to turn it
on.
Solution: I just had one of these come in. I opened it up, and found the U501
capacitor a little suspicious looking, in that it had a deformed top. It
was a 470uF 16V electrolytic 105degC 10mm x 12mm. I replaced it with a very
good quality 1000uF 16V electrolytic 105degC 10mm x 16mm Nichicon
UHN1C102MPD. After that repair, when I tried to turn it on, the LED was yellow for a second, then green, then I got a picture, and it appeared to
work great. I then asked the owner a week later how it was working, and they said it was working just like new!

I had this issue and Sharp sent out a local repair tech to install a new main circuit board, then two weeks later, a new side board (where the side inputs connect into the system)...

Source:BN96-03832A....I get to check Volts at connector that go to de LCD Lamps (connector out) At the board THERE ARE NOT +24 V. Pawer only has Voltages at rectifier who is 385 V and at rectifiers more o less the same rate.
I have observe something at the BLINKING LED. It glow at the cadence of' 4-4-4-4- 2 or 4-4-4-4 -2 and 4-4-2 and so. Does this led's glow means something?..
I have changed 5 capacitors in spite they were good by checking, but the pb is the same. Any another suggestion. Thanks by help.
Excuseme, but I have received your message about if your solution Fix my ..'MY SAMSUNG FLAT PANEL TELEVISION 25.5 in LCTDT 1920 X12000;...............? but I say to FixYa team THAT NO IS MY PROBLEM... My Source is: BN96-03832A-Samsung. I need Wiring, but it help to me if you said to me at what points it's neccesary to do a 'jump or bridge' in orden to check voltages at Power Supply with it OUT THE TV. I think it must be between "SOME CONNECTOR PIN of Power Source and Connector pin of Standby....The main connector of this Power Supply has 16 PINS with followings points: (16 Pins Connectors)...
Pin 1-Power on-off / 2-ST sys.5v / 3-5-GRN/ 6-8-+12v/ 9-11-GND/12-14-5.4v/ 15-GRN/16-+13v/ ...The second big Connector go to the LCD Lamps and it has 14 Pins Connectors.......Pin 1-5 +24v /6-9-GRN /10-NC /11-AD /12-On-Off /13-B/L /14-PD-----Like I explain at the begining of this saurce, Only have Voltages at the filter out who is about +385 Volts and 2-3 +volts at point +24v of connector that go to the LCD Lamps, ( with connector out of course).....but may be the +24v fails because with the connectors OUT the power need that "JUMP" between some points at the connector........OR NOT??? Thanks by your help..
To Gopakumar Gopalan.....Thanks by your suggestion of TRY PAID DOWNLOADS BECAUSE THERE ARE NOT FREE SERVICE MANUAL AVAILABLE NOW but I can't do it because Service Manual cost is not cheap for me. ...Repairing TV is not my business and I am a 80th years retired man and this TV of problem is mine. I studied Radio and TVC years ago and this repair is a HOBBY for me. If I can't repair TV then I must to get some repair center whose repair's prices are so expensive. Many thanks....
