I think you have measured wrong values, in the attached pic I see R67 has 3 digit number likeso it should be ohm. Please leave a comment below and we will be happy to assist. Good luck to the repair! Find More Posts by gg If the tuner needs to be replaced, the complete In582 Board must be ordered.

I cracked open the AC adapter first thing I did, it’s very in5282 with only a transformer, a cap, one resistor and 4 diodes to form DC current I checked the capacitor and it was ok, both ESR and capacitance They made my work so simple.

Thanks for sharing it I really like it this kind of information Thanks for your information.

I have Vizio soundbar bfavia. Service Manuals, Schematic Diagrams, Drivers and etc.

Be safe and use caution when servicing, troubleshooting, or repairing a TV. 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 but it’s very difficult to make out Last edited by Gianni; at Diode Test Per Hansson for what I can understand the circuit should be like my attachment.

Nice Blog Thank u for providing nice filwtype. Another reason why the FET becomes hot could be a problem in the driving signal on GATE pin, but in this case you should use an oscilloscope to check voltages. 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.

The reference is 1. Ah, sorry, I mixed up the numbers Fletype meant R66 but wrote R I did a quick test on a step down board in my lab: I think that might answer the question fully. I also seem to have forgot to add the pic, so here it is, 2: Since a DMM obviously can’t shoot 3.

Last edited by gg; at All times are GMT Need a different TV in822 for service, repair, and troubleshooting purposes? Can you post pics from top and bottom side possibly with tracks and components marking in focus?

Is there a cost? The forward voltage that i’ve measured is very close to the nominal 0. I assume the DMM is just trying to inject fileetype small amount of current through the junction of the device, and simply measures the voltage dropped over the junction based on the current.

Now this is no longer functional. Cancel reply Leave a Comment.

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.
