Re: Toshiba 32AV502R green blinking LED



Thanks for the reply.

I couldn't tell from those posts if 1N4148 was determined to be the original part, or just a replacement that seemed to work for you and @masessum....

Re: Toshiba 32AV502R green blinking LED

I found a Toshiba 32AV502R in the alley, and it had the same symptoms: powered on for a few seconds, then went into a loop where it would power on and and off every couple seconds.

I removed D200 and it seems to work now.

If it is part of the overvoltage protection circuit, I don't feel good running the TV without the diode. My concern is what function this diode serves and how to choose a suitable replacement. Is the forward voltage drop critical?
