I have a Calypso 40″ TV with the same problem.
Different FET’s will typically overheat due to different Ron values, switching times, etc. Find More Posts by fzabkar.
That big long board on the left is the Balancer Board. Actually, this photo looks more like my board see brown area on the left side: Thanks for any tips.
Last edited by budm; at This is one place where the original devices should be used. 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.
I will start a new thread. Please make sure to put the pin number, ratasheet by the pin names, and follow by the Voltage reading so we can tell which pin is which and what Voltage each one has.
All times are GMT Thanks to all who helped, I’m looking forward to my next adventure!!!

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. Page 1 of 2.

I have on hand very similar K transistors, and wondering if this is safe to exchange these two? Which picture show the scorched mark? The time now is For example, an “HBA” board claimed to be working, despite the burnt signs Do you think I can exchange the CNF1 connector from my bad board to one of these used boards?
I now see it, in that case, I must’ve tested the K incorrectly, maybe it is good after all Only the Diode settings shows signs of life as described datasheett.

The 24V should be a switched 24V which will not be present at the connector until datashedt power supply board gets the PS-ON signal from the main board. 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. Find More Posts by SteveNielsen.
All electrolytic caps are not bulged and look ok. You have to check specs on the parts to see if they are close enough. datashewt
Mar My Country: Looks like there are various versions of datasbeet power supply board. Find More Posts by Longbow. There is a burnt electronics smell with the tv on.
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.

Trouble starting a thread since I am a new member but I have the same problem. Briefly short S to G to bleed off any residual voltage. Find More Posts by neilc6. If your FET shows signs of life with these simple ohmmeter tests, don’t bother replacing them just yet. You aren’t doing something wrong. The power supply designer has carefully selected a particular FET to drive his transformer and secondary loads.
Can you post some clear hi-res photos of both sides of the actual board your working datasheey Find More Posts by budm.
Testing the board’s outputs, all except the 24v ccfl yields VDC. New York My Country: So what is the exact make and model of this TV and what is it not doing? Bay area My Country: If you see a low resistance, or a dead short such as 1 ohm, it is smoked. Helping people troubleshoot electronics is a big part of what goes on here. Last edited by stormy; at The second part of the s2k3569 involves putting a little bias on the gate.
