Transistor Replacement K => K – Badcaps Forums
The second part of the test involves putting a little bias on the gate. Page 1 of 2.
The power supply designer has carefully selected a particular FET to drive his transformer and secondary loads. Newport, OR My Country: From this thread, seems like I should replace the transisors mounted on the heatsinks and test the diodes in this area. The 24V should be a switched 24V which will not be present at the connector until the power supply board gets the PS-ON signal from the main board.
There is a burnt electronics smell with the tv on. Find More Posts by Longbow. If your FET shows signs of life with these simple ohmmeter dtasheet, don’t bother replacing them just yet.

You aren’t doing something wrong. Find More Posts by fzabkar. If they are NLA The time now is I’m pretty sure the other board does work, and does send the signals, since the speakers are powered from it, and they work, also it powers on the TV, i.

Only the Diode settings shows darasheet of life as described above. This is one place where the original devices should be used. Use a spare resistor of maybe K hooked between the D and G for an N-channel or between S and G for a P-channel Now the resistance will be low – the transistor is biased on. That big long board on the left is the Balancer Board. If you see a low resistance, or a dead short such as 1 ohm, it is smoked. So what is the exact make and model of this TV and what is 2k3569 not doing?
Please make sure to put the pin number, follow by the pin names, and follow by the Voltage reading so we can tell which pin is which and what Voltage each one has. You have to check specs on the parts to see if they are close enough.
Find More Posts by stormy Does this mean this is a good transistor? I didn’t realize I’m supposed to somehow measure from the TOP while the connector is in-place The 24V has nothing to do with that inverter section. The scorch is on the full picture of the back where the high voltage wires are taped down now burnt off probably from the heat from the wires.
Last edited by budm; at Can you post some clear hi-res photos of both sides of the actual board your working on? Actually, this photo looks more like my board 2sl3569 brown area on the left side: Looks like there are various versions of this power supply board.
I have a Calypso 40″ TV with the same problem. Originally Posted by stormy Find More Posts by trebo. Multimeter in Diode position: Find More Posts by SteveNielsen.

Different FET’s will typically overheat due to different Ron values, switching times, etc. New York My Country: I have on hand very similar K transistors, and wondering if this is safe to exchange these two? For example, an “HBA” board claimed to be working, despite the burnt signs Do you think I can exchange the CNF1 connector from my eatasheet board to one of these used boards?
I will start a new thread.
I now see it, in that case, I must’ve tested the K incorrectly, maybe it is good after all LEFT most pin marked 24V, comes at 12v, datasheft drops down as I measure, went down to 6V, and probably more, i just kept going. Resistance between S and D should show an open circuit.
Thanks to all who helped, I’m looking forward to my next adventure!!! All datasheett are GMT Helping people troubleshoot electronics is a big part of what goes on here.
