For a 1N, it gets about 0.
Looking filrtype other manual? 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.
It becomes like hotter than my soldering iron without the diode lol Anyway, so I measured the 1N diode while it was lifted, of course since it seems to be the problem I would change it but I don’t have a spare I also tested the D-Link switch with another known good filerype and behaviour was the same Unfortunantey I think I may have killed it now with my testing, before as I said without the diode or FET it would actually power up and blink it’s lights It did a real diagnostics test, first power turned on then it blinked each port’s light to let you know it was working Last edited by gg; at Diode Test more importantly what does it say in the reverse direction.

The post is absolutely fantastic! This manual also for: Any PMs asking for assistance will be ignored. The reference is 1. And the switching chip becomes very hot, so I think I cooked it. Per Hansson you can calculate the output voltage if you can identify the resistors connected between output-PIN5-ground.

Phoenix, AZ My Country: Looking at the tracks it seems to me that fuletype feedback resistor is R66 not R Per Hansson ignore the above message I’ve got a Fluke here in front of me at work, and according to it, it’s measuring volts DC.
Thanks for sharing filetypee I really like it this kind of information Thanks for your information. Now this is no longer functional. Diode Test 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. 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 Find More Posts by gg Be safe and use caution when servicing, troubleshooting, or repairing a TV. Diode Test I’m sorry it died.
The forward voltage that i’ve measured is very close to the nominal 0. Access the Service Menu by pressing the following buttons on the Remote Commander within a ldc Looking for a suggestion of what part will cause this? I assume the DMM is just trying to inject a small amount of current through the junction of the device, and simply measures the kn5822 dropped over the junction based on the current.
Diode Test I’ve got a Fluke here in front of me at work, on5822 according to it, it’s measuring volts DC. Warnings And Mabual Ne les remplacer que par des composants Sony dont le numero de piece est indique dans le present sony bravia lcd tv service manual filetype ou dans des supplements publies par Sony. Is there a cost?
Since a DMM obviously can’t shoot 3. You can check with the DMM if the circuit is like your board. Remember, amateurs built the ark. What I can suggest you for future opportunities is to try to test the power supply or step-down converter isolating it from the board if it is possible. To open downloaded files you need acrobat reader or similar jn5822 reader program. Find More Posts by starfury1. Nice Blog Thank u for providing nice information. Another thing I would do is to feed the board with an external PS, if you have calculated the voltage you can feed the circuit and check if it works.
Please leave a comment below and we will be happy to assist. I filetgpe tried the following without any success: Jamestown, IN My Country: I did a quick test on a step down board in my lab: Maybe there’s a short circuit after it and the current is so high to run it very hot.
I read nothing in the direction you should not be able to read anything And in the “forward” direction I read 0. Find More Posts by Gianni.
Ciao Gianni Last edited by Filehype at Diode Test Google for the 1N datasheet, on the second page, look at the “forward voltage characteristics”. Service Manuals, Schematic Diagrams, Drivers and etc. Diode Test Per Hansson ignore the above message Originally Posted by Per Hansson with it lifted there is 10v on the in side which is lifted Hence, it gives a voltage when forward biased, and no volts, indicates “OL” when reverse biased.
