The TV starting acting funny; every other day or so the screen would go blank for about 5 to 10 minutes and then come back on. I replaced the lamp but as soon as TV was plugged back in all five lights on front panel lit up and TV will not respond to any command.

It is a new tv.Take it back where u bought it and trade it in for another tv.This tv have those 2 LCD long inverter boards have problems.These 2 long LCD inverter boards are to help the tv LCD screen panel to have a backlight for the tv LCD screen to produced a picture.
prima lv-3228p lcd tv-after 15 mins of play the screen goes funny and there is still volume but the remote will not function. you cannot even shut the unit off, only by disconnecting the power supply. If you wait 15 -20 mins and plug the unit back in it will work for approx 15 mins again- then it will start acting up again?/

If you can first connect the Fios box via component and that will rectify the issue and still allow HD. HDMI is funny, if there is anykind of communication issues between the TV or the Fios box you see what happens. You might also call Samsung to see if there is ANY firmware/software updated for your TV specifically to fix such an issue with the Fios/Mortorola connection. If there isn't then the issue is the cable box since the TV works ok on HDMI with other devices.
This looks as if a component has become thermally sensitive. The best way to find this is to use component cooling spray. It looks as if the problem is localized to the tuner section. Take the back off of the TV and turn the TV on, wait until the problem occurs and lightly spray the tuner section with the component cooling spray watch for any reaction, then if this does not work spray the Microprocessor and the LVDS section and watch for a reaction. The set should go back to normal when it does that section is the problem, try to localize the problem to one component. Then replace that component.
