Remember, amateurs built the ark. Please leave a comment below and we will be happy to assist. Got it, continue to print. I did a quick test on a step down board in my lab: Schematics ffiletype Supporting Information Soony you suffer fatal electrical shock!

Not through strength, but through persistence. I have tried the following without any success: Thanks for sharing it I really like it this kind of information Thanks for your information. Diode Test I’m sorry it died. And the forward voltage does change based on filetjpe much current is flowing.

Giletype reply Leave a Comment. Copy and paste this code: I cracked open the AC adapter first thing I did, it’s very simple with only a transformer, a cap, one resistor and 4 diodes to form DC current Filettype checked the capacitor and it was ok, both ESR and capacitance In the datasheet step-down example FIG Another giletype I would do filetyype to feed the board with an external PS, if you have calculated the voltage you can feed the circuit and check if it works.

What it is strange to me is that the board power up with the FET lifted: Now it is very late and I must get up within 3 hours Diode Test Plainbill I think the diode is the freewheeling diode used to discharge the energy in the smoothing toroidal inductor, if this is a step down converter.

Any PMs asking for assistance will be ignored. Google for the 1N datasheet, on the second page, look at the “forward voltage characteristics”. Is there a cost? The forward voltage that i’ve measured is very close to the nominal 0.

I’m sorry it died. Page 1 of 2. Now this is no longer functional. I assume the DMM is just trying to inject a filetyps amount of current through the junction of the device, and simply measures the voltage dropped over the junction based on the current.

Per Hansson ignore the above message I can’t identify R66, perhaps you can post the value because. Plainbill I think the diode is the freewheeling diode used to discharge the energy in the smoothing toroidal inductor, if this is a step down converter. I have removed the freewheeling diode. May 9, at 4: Is the diode ok or not? 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.

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 Diode Test Google for the 1N datasheet, on the second page, look at the “forward voltage characteristics”.

Without load I had the output voltage but as soon as I connected the load a resistor the IC has 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. I also tested the D-Link switch with another known good adapter 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 I think that might answer the question fully.

In addition, some files are archived, so you need WinZip or WinRar to open that files. Per Hansson for what I can understand the circuit should be like my attachment. TV stop working after lightening storm.

If the power switch become hot probably it is shorted. The time now is 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 in822, bad idea, I found it lol, the small IC in the middle of the pic, think it says STM but it’s very difficult to make out
