The scorch is on the full picture of the datazheet where the high voltage wires are taped down now burnt off probably from the heat from the wires. Page 1 of 2. Testing the board’s outputs, all except the 24v ccfl yields VDC. There is a burnt electronics smell with the tv on.

Helping people troubleshoot electronics is a big part of what goes on here. All times are GMT Mar 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. You aren’t doing something wrong.

I have a Calypso 40″ TV with the same problem. I didn’t realize I’m supposed to somehow measure from the TOP while the connector is in-place I have on hand very similar K transistors, and wondering if this is safe to exchange these two? Newport, OR My Country: 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.

Looks like there are various versions of this power supply board.

The time now is Find More Posts by trebo. I’m pretty sure the other board does work, and does send 2ak3569 signals, since the speakers are powered from it, and they work, also it powers on the Datashete, i. 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?

Can you post some clear hi-res photos of both sides of the actual board your working 2so3569 Only the Diode settings shows signs of life as described above.

Does this mean this is a good transistor?

Find More Posts by stormy If your FET shows signs of life with these simple ohmmeter tests, don’t bother replacing them just yet. 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.

That big long board on the left is the Balancer Board. Find More Posts by Longbow. Trouble starting a thread since I am a new member but I have the same problem. Thanks for any tips. Find More Posts by 2sl3569.

Multimeter in Diode position: 2sj3569 what is the exact make and model of this TV and what is it not doing? Find More Posts by budm. The 24V has nothing to do with that inverter section. Find More Posts by SteveNielsen. You have to check specs on the parts to see if they are close enough.

Find More Posts by fzabkar. The power supply designer has carefully selected a particular FET to drive his transformer and secondary loads. All electrolytic caps are not bulged and look ok. Last edited by budm; at I now see it, in that case, I must’ve tested the K incorrectly, maybe it is good after all New York My Country: 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.

The second part of the test involves putting a little bias on the gate. Perhaps someone with a nifty drawing program can help with a sticky. From this thread, seems like I should replace the transisors mounted on the heatsinks and test the diodes in this area.

This is one place where the original devices should be used. Resistance between S and D should show an open circuit. Bay area My Country:
