IF I had the skills, I'd go through the board and replace everything. But I don't. And desoldering 8 year old solder is the devil.Re: Toshiba 42HL196 No power 3 blink...I'd go through

Re: Toshiba 42HL196 No power 3 blinking lights, possible Seine board
I have found others with similar issues at 880. Another gentleman replaced all the caps as well.
My soldering skills frankly are not very good. The reason why I bought a "new" power board to begin with are the result of me fumbling around and impregnating footballs and hosing the original board.
The good thing is that the Ebay seller just called me right back and refunded my money on the spot for the power board, which is rare in this day and age.Leave a comment:

Re: Toshiba 42HL196 No power 3 blinking lights, possible Seine board
Hi Bud, I appreciate you following up. I tested voltages going from the power board to the Low B board.
P807B
1 - 0.28V - supposed to be 12V
2 - 0.28V - supposed to be 12V
3 - 0.28V - supposed to be 12V
4 - 0.28V - supposed to be 12V
5 - 0V
6 - 0V
7 - 18V but then starts bleeding voltage down while I test it. Weird.
8-13 - 0V each
P809B
1-2 - 0V each (should be 30V)
3-5 - 0V each (ground)
6 - 0V (should be 24V)...Leave a comment:

I do hear a relay click on from the power boardwhen I plug the TV in. It sounds like "Tick Tock Tick", very rapidly. I can trigger the relay to come on again with the power button....Last edited by weargle; 10-19-2013, 10:17 AM.Leave a comment:

Re: Toshiba 42HL196 No power 3 blinking lights, possible Seine board
I'll check. All four boards have been replaced with eBay units that supposedly came from working units and from good sellers and I still have the three blinking lights issue. To say I'm frustrated is an understatement.
The four boards are power supply, Seine, Low B and AV. So literally none of the guts are the same as what came from the factory.Last edited by weargle; 10-19-2013, 10:12 AM.Leave a comment:

Re: Toshiba 42HL196 No power 3 blinking lights, possible Seine board
It's what I would call "steady state" voltage -- tv plugged in, won't power on, testing at the points called for in the flowchart to a chassis ground.
Thanks for the followup.
I found both the AV board and the Low B board on Ebay for $30 shipped each, so I went ahead and sprung for both of them. The TV was free, and I will have replaced all four boards in it for a whopping total of $210. I'm rationalizing it because it's cheaper than even the cheapest of new 42...Last edited by weargle; 10-14-2013, 02:28 PM.Leave a comment:

Re: Toshiba 42HL196 No power 3 blinking lights, possible Seine board
Well, I got a new Seine board in today, and swapped it in. I'm now seeing .74V at pins 8,9 and 11 of CN90A. Which means that likely something was bad with the existing Seine, or at least that was my suspicion.
I went through the flowchart again, confirmed the same voltages for CN49A and P812A as shown above. Now that I have a voltage at step 3 of the troubleshooting reading at 25% of expected, I checked Pin 8 of P812A. I get 3.10V out of 3.0 expected, or 94%.
Now is where I wonder...Leave a comment:

Also, I disconnected CN90A, and the red blink went away and was replaced by a steady blinking blue light. I've read elsewhere on the internet that unplugging the Seine will fix the issue. Not so in this case.Leave a comment:

Re: Toshiba 42HL196 No power 3 blinking lights, possible Seine board
Bringing this old topic back up from the dead.
I have a 42HL196 with the three blinking lights of death, and attempted to replace the STRW6765 chip. Admittedly, my soldering is not up to snuff, and I think I damaged the original board. I found a reportedly good replacement online, and swapped that unit into the TV and still have the blinking three lights. This leads me to believe that the issue *isn't* the power board.
I'm following the troubleshooting guide (I really appreciate the...Leave a comment:
