Panasonic TC-P65S2 no good HDMIs left - Suggestions?
Several years ago during a heavy storm, I got a surge on my cable line which took out the cable box, the A/V receiver HDMI connected to it, and the HDMI input on the back of the Panasonic TC-P65S2. (It actually took out BOTH HDMI inputs to the TV). But HDMI3 still worked (on the side of the TV). SO for years I just used the side HDMI input-
Two weeks ago the same thing happened - Cable box, A/V receiver HDMI, and the last of the Panasonic HDMI inputs. I've already replaced this TV, and I am at a point where I need to determine what to to with this broken beast. It is still in "like-new"... -

Never figured it out. Discarded.Leave a comment:

Re: Panasonic VIERA TC-L32X5 - One LED blink
Done.. The best I could do. There are no visible discolorations, puffy/leaking/smelling like fish caps, etc with the exception of diode D7306 (The legs are pretty tarnished).
I even brought tout the headgear magnifiers to check for burns/discolorations.Leave a comment:

Re: Panasonic VIERA TC-L32X5 - One LED blink
Link fixed- The additional photos are showing the two LED strips, and the one that goes *almost* completely dark after all the LEDs flash on really bright.
It looks like each strip has about 36 LEDs.
C7806 starts at 46VDC, then jumps up to 135V, where is stays until the TV shuts itself off.Last edited by WannaTheater; 06-18-2017, 08:48 AM.Leave a comment:

Yes- There are two LED strips running along bottom.

I took video, slowed it down, and although it is difficult to be 100% sure (due to brightness), I do not see any LEDs out.
At this point, I am about 85% sure this TV is going to the trash
Re: Panasonic VIERA TC-L32X5 - One L...Yes- There are

Re: Panasonic VIERA TC-L32X5 - One LED blink
After disassembling the panel, here is what I found:
- There are two LED strips at the bottom of the TV- One for the right half, one for the left half.
- When the TV is powered on, they both turn on. Then the left one turns off (the whole strip). This repeats twice more, then the TV turns off.Leave a comment:

Re: Panasonic VIERA TC-L32X5 - One LED blink
Continuing to experiment:
1) I swapped the two pairs of wires in the header- No difference
2) With the LED header disconnected, the TV still cycles through and shuts itself down, leaving the 1 blink red LED
3) I have tried with one pair disconnected, and then the other. TV still shuts down.
If the TV is still shutting down while the LEDS are disconnected, wouldn't that imply there is another protection shutting it down?
I am unsure of what the panel inverter is (per 1 blink code).Last edited by WannaTheater; 06-17-2017, 03:58 PM.Leave a comment:

Re: Panasonic VIERA TC-L32X5 - One LED blink
Unless I swap the wires in the header, I cannot easily switch them (I have not disassembled the panel).
When measured to chassis ground:
Pin 3 (LED1) is 46Vdc
Pin 6 (LED4) starts at 46Vdc then drops to 1V quickly
LED2 and LED3 are not connected.
When I disconnect the panel from the Power supply board, both pins 3 and 6 are +5Vdc.Last edited by WannaTheater; 06-17-2017, 03:34 PM.Leave a comment:

Re: Panasonic VIERA TC-L32X5 - One LED blink
Ahh. Thanks. Odd question- Should I swap the two cables to see if the problem follows the cables?Leave a comment:

Re: Panasonic VIERA TC-L32X5 - One LED blink
What is odd is that the all the LEDs light up initially, then one side shuts down, then they all light up again, then one side shuts down, etc. This makes me think it is not the LEDs, but the circuit driving them- I assume that when an LED fails... It FAILS completely (i.e. won't come on). It is also odd that the TV is shutting off. Much of what I have seen with LEDs failing is that the TV stays on-
I will try to measure voltages if possible-
Also, my assumptions may be wrong!Leave a comment:

Re: Panasonic VIERA TC-L32X5 - One LED blink
Here is a link to 4 photos. The fourth shows how the the right half is dark. From the self-test, it looks like it reset the TV back to factory. Note, I took this photo right before the TV turned itself off.

Let me know ifLeave a comment:

Re: Panasonic VIERA TC-L32X5 - One LED blink
Just checked- There is no way for the VESA mount screws to do any damage- They have their own mounting holes on the chassis, and are inches from any electronics or cables.Leave a comment:

Re: Panasonic VIERA TC-L32X5 - One LED blink
Diif- I cannot be positive that the two are related. I had not turned the TV on in 6 months. I should have tested it before I hung it up-Leave a comment:

Re: Panasonic VIERA TC-L32X5 - One LED blink
I will try to get some pictures, but inside looks brand new. No screws pierced anything, nothing burned, very clean. TV was purchased in around 2012 or 2013, with minimal use.
I just managed to get the self-test to run, and it shows everything OK.
(everything on the remote and menu seems to works fine, but I have to do things fast.. I only get about five seconds after turning the TV on before it shuts down). Then I have to unplug, plug back in, and start again.Leave a comment:

Re: Panasonic VIERA TC-L32X5 - One LED blink
I should also add that this TV was working fine about 6 months ago. I recently put a bracket on the back (VESA), mounted it on a wall, turned it on to find it didn't work. Not sure if it stopped working because it sat for a while without turning it on, or if hanging it up perhaps shifted the case on the back??/ (just guessing here now)Leave a comment:

Panasonic VIERA TC-L32X5 - One LED blink
Hi all- First post here. I have a Panasonic TC-L32X5 TV, that is doing the following:
- Right half of screen is dark, "HDMI 1" is displayed, "No Signal" is displayed, then TV turns off, with the RED LED blinking on and off repeating (1 blink per repeat)
With the back off, it looks like the following is happening inside the panel when the TV is turned on:
1) Entire panel lights up (white LEDs? inside the metal casing, that I can see through holes)
2) Right side goes dark
3) Entire panel lights up a second time
4) Right... -
