There is a burnt electronics smell with the tv on. Page 1 of 2.
LEFT most pin marked 24V, comes at 12v, and drops down as I measure, went down to 6V, and probably more, i just kept going. Perhaps someone with a nifty drawing program can help with a sticky. Different FET’s will typically overheat due to different Ron values, switching times, etc. Find More Posts by stormy 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. New York My Country: I will start a new thread.
Briefly short S to G to bleed off any residual voltage. Only the Diode settings shows signs of life as described above.
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 it not doing?

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.
If they are NLA Looks like there are various versions of this power supply board. I have a Calypso 40″ TV with the same problem.
Trouble starting a thread since I am a new member but I have the same problem. I didn’t realize I’m supposed to somehow measure from the TOP while the connector is in-place Newport, OR My Country: I now see it, in that case, I must’ve tested the K incorrectly, maybe it is good after all You aren’t doing something wrong. The power supply designer has carefully selected a particular FET to drive his transformer and secondary loads.
Resistance between S and D should show an open circuit. Find More Posts by SteveNielsen. 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 dagasheet. This is one place where the original devices should be used.

From this thread, seems like I should replace the transisors mounted on the heatsinks and test the diodes in this area. I have on hand very similar K transistors, datashdet wondering if this is safe to exchange these two?

I’m planning to just replace and see if that area of the board puts out the marked 24VDC, and if not, find the exact K transistor. Bay area My Country: Last edited by stormy; at Can you post some clear hi-res photos of both sides of the actual board your working on? Find More Posts by Longbow. The 24V has nothing to do with that inverter section.

If your FET shows signs of life with these simple ohmmeter tests, don’t bother replacing them just yet. Does this mean this is a good transistor? The time now is Actually, this photo looks more like my board see brown area on the left side: All times are GMT Thanks for any tips.
Multimeter in Diode position: For example, an “HBA” board claimed to be working, despite datasjeet burnt signs Do you think I can exchange the CNF1 connector from my bad board to one of these used boards? Find More Posts by neilc6.
