09-10-2010 | Hi | I think you are right to say that there is a short circuit, but the question is what could have caused it.
Ok to prove the short circuit, change your meter to continuity, where when the to tester wire are connected together, it makes an alarm.
When that |
09-10-2010 | Ilo 26HD | It is the MAIN Board that is the problem. Replace that it will be as good as new. Doing so, you will have to get a remote the will operate it. Your original remote won't work with the a different board. |
10-10-2010 | | Do the buttons on the set function normally? You may have inadvertently disabled the remote control functions. |
10-10-2010 | | Check the transformers on the inverter/inverters for signs of damage also. |

10-10-2010 | | To forward bias a diode is only .6 to volts DC. Unless it's a zener diode. Let me think on this one but I would suspect a bad diode. Check/replace C504 22@50, C113 2.2@50, C633 10@35. Then suspect D523. |
10-10-2010 | | If you catch it soon enough you can resolder the transistors, it's too late. Replace the power supply. Burnt foils and trying to figure out part numbers isn't worth the time. I can hunt up the part numbers if need be... |

B501_1 is a ferrite bead. Acts like a coil.
Check R501, F502, Q502 and Q514
