Re: Toshiba 42HL196 - Clicking relay, Power Board

So it is the new PFC IC that is bad! I wonder if it is faked IC.
I am so glad you still the old one to put in, thanks for not giving up.

Yes sir. seems that way. One or both of the other 2 may have actually been bad as things changed when I originally replaced all 3, but I wasn't expecting that to happen. Thanks for all your help.

Lol you beat me to it. I was just about to post that when I was working on mine. It originally had the relay clicking problem and I replaced the three ic's and that solved the relay issue but led me to other issues which is irrelevant in your situation. Congrats on sticking to it. What I would do is leave the tv hooked up and on for a good 4-5 hours straight to make sure no issues. Cause when I fixed mine originally. I tested it and it blew one of the ic's after being on for a hour or two cause these three especially the q880 I believe gets hot.

I let board run overnight and all is well. Shut it down and will wait for resistor to arrive tomorrow I hope and replace board in TV and see what happens.

Re: Toshiba 42HL196 - Clicking relay, Power Board

im going to reccomend changing these parts 1 at a time!!! I too recd 3 parts from ebay and changed all 3 and ended up with a dead PFC circuit
the SRX2039 I suspect is a chineese knock off and luckily my original was good!!
so after 4 hours or pulling my hair out the STRW was the original problem which did come in the kit was the original problem but becuase i put in a crap SRX I went nuts trying to figure what I did!!

Replace 1 at a time and if the symptom gets worse STOP!!! put the old part back!! ARGGHHH

Re: Toshiba 42HL196 - Clicking relay, Power Board

Got resistor, all 200 of them. Took me 3 to get one on there. Removed all attached resistors and wires from the board and reassembled the board back in the TV. I have no signal to input other than a PC, but it has an image as you can see!!!! Yes, I know it is upside down, but I have no stand so it is very versatile. Thanks again to all and if audio and other inputs function correctly, I will have to find somethng else to work on. Bye for now.
