From this thread, seems like I should replace the transisors mounted on the heatsinks and test eatasheet diodes in this area. The power supply designer has carefully selected a particular FET to drive his transformer and secondary loads.
Thanks to all who helped, I’m looking forward to my next adventure!!!

Thanks for any tips. 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? 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. Datasheet electrolytic caps are not bulged and look ok.
Newport, OR My Country: Page 1 of 2. Only the Diode settings shows signs of life as xatasheet above. Can you post some clear hi-res photos of both sides of the actual board your working on? You have to check specs on the parts to see if they are close enough.
Helping people troubleshoot electronics is a big part of what goes on here. Find More Posts by momaka.

There is a burnt electronics smell with the tv on. If they are NLA Find More Posts by Longbow. 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. I have a Calypso 40″ TV with the same problem. If you see a low resistance, or dataaheet dead short datzsheet as 1 ohm, it is smoked.

This is one place where the original devices should be used. I will start a new thread. Last edited by stormy; at Find More Posts by budm. The second part of the test involves putting a little bias on the gate. Multimeter in Diode position: So what is the exact make and model of this TV and what is it not doing? That big long board on the left is the Balancer Board. Originally Posted by stormy 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.

Looks like there are various versions of this power supply board. Find More Posts by neilc6. You aren’t doing something wrong. I now see it, in that case, I must’ve tested the K incorrectly, maybe it is good after all Actually, this photo looks more like my board see brown area on the left side: Find More Posts by stormy Bay area My Country: New York My Country: 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.
Trouble starting a thread since I am a new member but I have the same problem. Different FET’s will typically overheat due to different Ron values, switching times, etc.
