Yes Rs232 is set to debug and the watchdog is set to off.
After i start thetv first it show the messagge no signal... then if i wait for 2 minutes the red led of power is blinking

Then your pins aren`t connected properly. No more reasons to don`t work.
drivers for cable also ok?
cable test - ok? (connect tx and rx with each other and see if you get typed symbols in terminal)...

I try to connect with a jumper the second and third pin of db9 connector of my serial cable and i get back the typed symbols in terminal, then i try to connect with a jumper the second and third pins of my hd15 pins connector and the result was the same so i think that the cable and the adpator works so why i don't get info from tv?
For my test i use the program RS232 Terminal 1.2.0. and in it the data that i send with tx i get back from rx so the cable and the adaptor seems to works...right?
(The second pin is RX The third pin is TX)
Any other suggestions?

[juusso]

Swap rx and tx on adapter

Do you sue that if this cable output is TTL? I don't think if its TTL but instead using +8 -8 volt. This might problem...
TV serial port cannot controlled with high voltage RS232 but "TTL" voltages, like v3.3...

I don't know if you already burn your serial port at TV but you can try to buy this ultra pricey dongle for your job...

The prolific is default a non ttl !!!
Try the sugested ttl converter.
Hope you didnt smoked the tv

Thanks for reply but i dont understand why my cable isn't ttl it has the same chip in it prolific pl2303hx so why isn't ttl?

[nspierbundel]

Does your proliffic explicitly mention it is ttl ?
I also have prolific 23xx usb to serial. Non ttl.
If it says ttl than I m wrong and it should work.
Have you crossed rx and tx?
