Hello, I have a Panasonic TX-68PS20A 68cm (29") Television with a GP3 chassis. (Australian PAL model) The documentation I have found online says that the gp3 chassis supports VHF PAL-B/G and NTSC-M. However my tv doesnt support M audio. It just tunes the video and gives white noise through the audio since it's looking for B audio even though it's displaying ntsc video just fine. I have found no options for this in any of the service menus I've accessed. Am I missing something? I don't mind if I have to reflash something to make this work. Here is the pdf which I read the specs from, it's not for this model but a similar one with a gp3 chassis. http://elektrotanya.com/cgi-bin/download2.cgi?uid=37145&cid=1417425157&fid=117149&file=panasonic_tx-29psxx_gp-3.pdf&x=26&y=30

Sziasztok! Most került hozzám, azzal a hibával hogy nem lehet bekapcsolni. Szétszedve kiderült hogy a sorvégtranyó átvezet, S2055 volt benne, de most mindig ellövi. Volt itthon 2SD2499, de ez is csak 10 percig bírta, eddig cseréltem a 8n2/2000V, 680pf/2KV, 1nf/2KV, forrasztási hibát nem találtam. A rajzon meg nem lehet kivenni, hogy milyen tranzisztor van benne 2SD144. , vagy mivel lehet helyettesíteni, vagy mit nem veszek észre?

Sziasztok

I got a broken Panasonic that will not start. It does show the red front LED and the power supply delivers 5,3Volt standby. Only when you try to start by remote or push button on the set it will only flash the red LED and does nothing more.

After a while, the red LED will start to flash repeatedly 13 times.

Since the 5,3 Volt standby run straight to the main board I wanted to check there but no luck finding the schematics.

Any insights?

After several attempts the TV finally started and I could enter the menu screen. Normal functionality. But after switch off it takes again several attempts. What is going on ?
