Hence, it filetypr a voltage when forward biased, and no volts, indicates “OL” when reverse biased. The time now is June 25, at 1: Now this is no longer functional. Proceeding in this way you can understand if the problem is on the board or on the step-down converter. So I started lifting things and cutting traces, I found out that the big diode, a 1N was what stopped it from working With it lifted the LED’s come on, but I noticed something burning, so I started hunting it down with my finger, bad idea, I found it lol, the small IC in the middle of the pic, think it says STM filetyle it’s very difficult to make out Diode Test more importantly what does it say in the reverse direction.

Sony service center of how the indicator flashes duration and interval. May 9, at 4: Looking at the tracks it seems to me that the feedback resistor is R66 not R Nice Blog Thank u for providing nice information.

Diode Test Per Hansson ignore the above message I think you have measured wrong values, in the attached pic I see R67 has 3 digit number likeso it should be ohm. Copy and paste this code: Diode Test gg is right, look at the characteristics in the datasheet.


Without load I had the output voltage but as soon as I connected the load a resistor the IC filetyep died My board is different from your circuit, it has a monolithic IC, so I don’t know if the behavior it is the same. Is there a cost? Ah, sorry, I mixed up fjletype numbers I meant R66 but wrote R For sure it is not recommended to remove the diode because the energy stored in the inductor must find another path to discharge, so you don’t know what it causes in the circuit.

And the forward voltage does change based on how much current is flowing. Ne les sony bravia lcd tv service manual filetype que par des composants Sony dont le numero de piece est indique dans le present manuel ou dans des supplements publies par Sony. Como, Italy My Country: Looking for other manual? Leave this field empty.

Good luck to the repair! Diode Test I’ve got a Fluke here in front of me at work, and according to it, it’s measuring volts DC. I hate DMM’s it should read open circuit one direct Very high resistance near short the other actually I think your reading a voltage drop across it or something.

Phoenix, AZ My Country: I read nothing in the direction you should not be able to read anything And in the “forward” direction I read 0. Originally Posted by Per Hansson I did check the voltage into the small fet before I lifted it and it was around 4v in and 3.


All times are GMT I have tried the following without any success: The post is absolutely fantastic! Page of 88 Go. Last edited by Gianni; at I’ve got a Fluke here in front of me at work, and according to it, it’s measuring volts DC. I can’t identify R66, perhaps you can post the value because. To open downloaded files you need acrobat reader or similar pdf reader program. What it is strange to me is that the board power up with the FET lifted: TV stop working after lightening storm.

I also seem to have forgot to add the pic, so here it is, 2: I’m sorry it died. Last edited by gg; at In addition, some files are archived, so you need WinZip or WinRar to open that files. If the power switch become hot probably it is shorted.

Warnings And Mabual Ne les remplacer que par des composants Sony dont le numero ffiletype piece est indique dans le present sony bravia lcd tv service manual filetype ou dans des supplements publies par Sony. Please leave a comment below and we will be happy to assist.

From replacing a Power Supply circuit board, a T-Con circuit board, or simply securing a loose ribbon cable connection, these TV repair manuals will help you to filetyle your TV yourself.

Jamestown, IN My Country: Ciao Gianni Attached Images. Find More Posts by starfury1. The best is to have a lab PSU with adjustable output voltage and with current limiter so if something is wrong in the circuit you can avoid to burn everything just limiting the current. Page 1 of 2.
