Re: tcp50g10 one blink
I have a couple of open circuits on the test points specifically TP46. Would there be any set OPEN when there was no power on the board?

Re: tcp50g10 one blink
Ok so I let the power bleed off for an hour before swapping boards and retesting the end result was identical.
5 Flashes with everything plugged in and 6 with the SC board removed.
SO it must be the SC board.
I see on eBay that people have "rebuild kits" for the SC board. Looks like transistors that are commonly blown on these units. How hard is it to soldier those things on?Leave a comment:

Re: tcp50g10 one blink
So I plugged everything in and got a 5 flash error.
also
Did the recommended SC2 & SC20 to get the SC board out of the equation and got a 6 flash error. Which the manual says is the SC, SS, SD, or SU. sigh....Leave a comment:

Re: tcp50g10 one blink
Well now for some reason I plugged in the NEW A & P boards only and got exactly what you described.
It powers on the fans spin and the red light stays constant with no blinking or anything else.
Could all my tests and swapping have been being interfered with residual power still being in the Power Supply board?
Going to plug it all in after an hour and see if it works or what I get for errors. Certainly an hour is long enough for the power to drain off the boards.Leave a comment:

Re: tcp50g10 one blink
I have a second P & A boards that I bought on EBAY from "previously working units" No matter what combination of the four boards goes in the results are the same. Could the problems lie in the SC or SA boards?Leave a comment:

Re: tcp50g10 one blink
Pin 12 on the p25 registers 3.096v But I could not find what the correct voltage is supposed to be. I am a lay person when it comes to this stuff.Leave a comment:

Re: tcp50g10 one blink
Ok here is what it does.
two clicks
pause
one click
pause
two clicks
pause
one click
pause two clicks
Then it stops. If you press the power switch again it will click once and then have a solid red light but nothing with happen. You can click it off again which it responds to. Switching it back on will either go through the two click one click thing or click once and give you four flashes....Leave a comment:

Re: tcp50g10 one blink
I will double check the readings
p25 was 5.17
&
p7 at 5.17Last edited by cmclemens; 05-23-2014, 06:49 PM.Leave a comment:

Re: tcp50g10 one blink
SO what now go around the whole unit and disconnect one board at a time and see when the error changes?
Is that even really possible?Leave a comment:

Re: tcp50g10 one blink
Oh and I just looked. I have the 2009 model via the serial number sticker on the inside of the panel.
P7 pin 5 and P25 pin 9 are the STB 5v lines both test between 5.4-5.6 volts.Leave a comment:

Re: tcp50g10 one blink
What would be the likelihood that I have two bad A boards?Leave a comment:

PANASONIC TCP50g10
Ah the mystery single blink. The manual has little to no information on this code. ONE BLINK does not even show up on the main block diagram for possible starting points. I have purchased a Power supply and A board. Switching them out in any order does nothing and I continue to get the ONE FLASH.
I have tested the referenced 5V STB lines on A25 and it comes up fine.
One other thing it does. If I disconnect everything but the P & A boards the unit will not boot but instead clicks 3-5 times and then stops. If I plug in the SS board the... -
Re: Panasonic TC-P50G10 10 blink code
Tested the STB 5v pins on the p25 & p7 both test ok. The 5v pin on the a33 ribbon does not show any voltage but that might because its not a Standby connection like the others.
Still one flashing, should I post this as a new thread?Leave a comment:

Re: Panasonic TC-P50G10 10 blink code
Ok new PS and new A board with a reset it flashes once.... The manual has almost no information on the single flash. SIGHLeave a comment:

Re: Panasonic TC-P50G10 10 blink code
OK new PS and with everything disconnected to isolate the A board and power supply the unit just clicks three or for times then shuts offLeave a comment:

Re: Panasonic TC-P50G10 10 blink code
OK pulled all the wires and disconnected the board. Still flashing... Since I have another A board and its flashing too it must be the Powersupply, right.Leave a comment:

Re: Panasonic TC-P50G10 10 blink code
Double checked, they were removed properly. Ireset the unit again and now I have four flashes which is the p boardLeave a comment:
