    i can buy each board seperately, but not sure which one?

    The main system control memory IC & system control IC can be located at the main board itself. If you replace it or you replace the main board as card basis; a firmware update might be necessary. It is a skilled work. That is why I said to contact any service technician. OK?

My pioneer pdp-4270xd loses the channels when I turn it off. which board do I need to change to fix this?


Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
[Fault: Main system control memory IC fault. This is a very small IC; have 8 solder terminals, and can be located very near to the main system control-chroma IC. Check and replace it. Be sure to replace it with the same number printed on it; in all respect. Otherwise, it won't go.]

I'm Italian and I live close to Gorizia, I can't see some DVB channel with my PDP-4270XD TV plasma. Other TV set haven't any problem. It's necessary to make a new Download? Please give me a...


You might try this.
Go to the Scan for More Channels option in TV Signal Setup.
First delete all the channels shown and then do a rescan.
This worked for me when my cable company switched to all digital.
For some reason WMC picked up the old channel map on the existing
channels and I could not tune them even though they showed in the guide.
Hope this helps! Take care and please Remember to rate/vote and give me

Tv stuck on standby


Power supply probably needs to be replaced if you don't even hear the relay click after the power is switched on.
