Question about Toshiba 61A60 TV
I went to Best Buy and bought a new 61" Samsung DLP to replace my 61" Toshiba. I wanted to move the Toshiba into the kids play room. When I got home the TV was on and it was on an input that had a blank screen. (I didn't turn it off) I powered up the device that was connected to that input which was a Digital Entertainment Center by HP. It started up and the screen was mostly blue except the HP startup logo. I walked into the kitchen and a few minutes later I heard a loud click. It sounded like a circular breaker popping. I looked back and the screen was blank and the red power led was blinking. (3 minutes topps it lasted after I bought a new TV).
I pulled the chassis out minus the power board which I left in and checked every fuse, diode, and rectifier and found nothing wrong. I replaced the STK parts and same problem. There was no audio playing at the time. I believe the flyback xformer might have blown, but I'm not sure. There was no smoke, and no burnt smell.
If this is my last hope, where can I find a replacement? I've looked everywhere for the part (Toshiba 23236623 or TFB3086AD) and I can't seem to find one.
Is there anything else that it might be that I am not checking. I looked at everything on the mating board except any small surface mount parts. Also, is there a way I can verify that the flyback is bad? I don't see any bulges, crackes, or burns.
Have you check the HOT Q404?
I would suggest to check that transistor before you decide to replace the flyback. The way to know if you are getting high voltage would be to pay attention for like a charging/discharging static noise when you press the power button to turn the TV ON or OFF.
Let me know if you require further assistance.
