Hello:
The highest resolution cable you can use to connect your LG RZ-BA10 to your LG MZ-42PZ14 is an RGB cable. RGB is for video only. You will have to use an RCA audio cable.

hi would you like to sell your box as i need one ? thanks paul

check using other player ..
to conform wether the tv line is clear...

hi yes your box has gone the same happend to me

It souunds like te TV is having problems with the streaming data being applied Most plasmas with DVI connections were actually designed for PC type input signals  Unfortunately the TV's input may not be able to stand up to the stream of signal the DVD or cable box wants to display. You can try and lower the output of both devices to 720P Good luck to you

Problem is probably with your cable box as you have confirmed that the set is working by using the dvd player, that is unless you have a bad cable for the cable box.

I wish I had an answer for you but I'm in the same boat. I've got a 42pc5d and it's doing the same thing. I'll turn it on using either the remote or the power button on the unit itself. The LED will blink either two or three times, then shut itself off. I tried plugging the unit into a different outlet. I tried unhooking all inputs (PS3, DVD player, antenna, etc). The tv was still shutting itself off. I called tech support and the lady who answered asked me if there was a power button on the unit. Well, of course I understand LG has hundreds of models but I felt like I was dealing with someone who didn't care enough to even open the manual to see for herself. Anyway, after a "reset", the TV is now nothing more than a very expensive paperweight. To say I'm displeased is an understatement.

So, does it always say 'No Signal' or does it come up when you get it connected? If they are off when you are connecting them, that sounds okay; you'd get a signal when you turned the DVD player on (and told the TV to pay attention there.)

You might need to get an upconverting DVD or SVHS machine (since those are not normally HD) to get the TV to tolerate the signal, but the TV menus might let you activate that too. Why not look up the HD Plasma TV manual online according to the model number? If it turns out to be a monitor rather than a TV; of course, that is why it would not display those signals...you would need a separate tuner or signal selector box for that.

What's that bumpersticker abbreviation... ROFLMAORTFMYGDSOB? Good luck checking those out, since you get to decide which box renders the SD signal into HD....
