Panasonic TGH-42PZ70B, not recording time of use/sos errors

[Alastair E]

Odd one--not affecting anything--but this set doesnt seem to have recorded its recent sos-errors or the use/time on times.

The boxes where the info should be are in case of time of use--empty and the sos all indicates 00, 00, 00 etc...
Pressing 'mute' for more than 3 secs does nothing.....

Try a reset?

VOL- on TV for 3 seconds, "0" on remote 3 times. Turn it off when diag page appears and it will boot as fresh from the factory.

Hi Tom,
Will doing that not erase any SOS and hour-meter reading?

Just curious really, Ive shoved it up on the wall--in place of the LG 42PC1DA....

Very fine pitch panel--no wonder they had problems making them--This one has the odd green pixel out, but not really noticable from more than 2 foot distance....

Great picture on it....

It will reset SOS but not hour counters.
If you are getting some pixels not firing bump up Vsus by a couple of volts, on the P board.

Ah--OK....

As to the pixels--Not too worried about it, and with the apparent reputation of these 42" FHD 1st gen ones--dont want to push my luck....

BTW--That hand-written voltage-marked on the panel for Ve and Vsus--Aint that clear either! Really can tell whoever wrote it doesn't normally write English numbers!

Hand calibrated by an engineer in Japan, same for most early Panasonic panels. It was an achievement to get over 3 million pixels in a 42 inch panel, so they did have to calibrate them by hand to get them to work right.

Would be a good idea to install the SOS7 software update (prevents SC board failure; although it's only one transistor so not too hard to fix) - tw2005 I think has a copy.

Most of Japan, especially science and engineering, use Arabic numerals ("English" numbers), the same as we do. However, handwriting styles are different, and are especially poor for most engineers!

No, I've got nothing like that at all. Maybe someone else.

Ah right, had a look on Panasonic website--pretty useless for anything older than 2010 year, Not impressed with that....

Will start another thread asking if anyone has it.....
