panasonic tc-p60st30 won't turn on

[ealequi]

I have a 60 inch panasonic plasma 3d hat it won't turn on. led light give 7 blink. I had check all fuse and they are good Change board ss, ss2 and main board and still soing the same.( the board i put on were used ) Any idea what can it be?

Re: panasonic tc-p60st30 won't turn on

7 blinks is SC, SU or SD. Not SS. And SS2 is a piece of copper disguised as a circuit board, really nothing on there to go wrong.

Re: panasonic tc-p60st30 won't turn on

sorry my mistake is not 7 is 8 blinks

Re: panasonic tc-p60st30 won't turn on

In which case it is the A Board misdiagnosing 8 blinks, possibly. Check TP_SOS8 on SS board. There is also the possibility of it being a bad panel.

Re: panasonic tc-p60st30 won't turn on

ok, I put another a board and still doing the same, 8 blink, i went ahead and disconect the three ribbon atach and went i turn it on it no longer blink. I attach ribbon a32 and still power on no blink but went i attach ribbon a31 or a20 the led light start blinking. Any idea or the answer still the same?

Re: panasonic tc-p60st30 won't turn on

This is possibly a bad panel (detection error, not necessarily too bad to display an image.) You may be able to disable the 8 blink code to see if the picture is good. Short the TPSOS8 to ground using a 100 ohm resistor, and it should fire up, although you may see a 6 or 7 blink error.

Re: panasonic tc-p60st30 won't turn on

sorry but what do you mean when you referred to TPSOS8? IS THAT SUPPOST TO BE ON THE MAIN OR ON THE SS BOARD

[tom66]

Re: panasonic tc-p60st30 won't turn on

It's on the SS board near the connector going to the A board.

Re: panasonic tc-p60st30 won't turn on

got it. Going to radio sharp to buy the resistor. will keep you inform. Thanks.

Re: panasonic tc-p60st30 won't turn on

Ok, i did what you toll me and now iam getting 6 blick but no picture or sound. Went i press the remote i see the led light reacting.

Re: panasonic tc-p60st30 won't turn on

So I suspect a bad plasma panel in this instance.
You can try and rule out the SU and SD by unplugging them.

Re: panasonic tc-p60st30 won't turn on

yeah, i unplug them and nothing happen. Not having much luck this days

Re: panasonic tc-p60st30 won't turn on

Inspect the panel carefully for cracks and marks on the screen under the glass.

[tom66]

Re: panasonic tc-p60st30 won't turn on

Huh, is this with SC or SD removed, or what?
