Pdp-4300 the tv does not work , do i need anything else to make it working

Look to see PIP or picture in picture is not engaged as it may be doing this.

Try it on headphone. Try changing the input to some other device that works. If it does not work even then, this may need attention by a qualified service technician.

Cable call you cable provider and ask them for a HDTV box

Satalite you should already have one if not ask them.

OTA =over the air you need a digital tuner with a nice antenna I suspect this has a digital tuner inside so all you need is a good antenna.

DVD= hook the DVD up with the red,green,blue cables called SCART connections..

Blueray= Will bring you high def.. with its connections.

So your question is vague and can be answered in so many ways.. Rate me please

Plasma tv's are known for having overheating problems. Most of these problems occur in the main power supply. Most technicians only replace these boards due to manufacturers policy. If you are lucky, you may find a local technician that can troubleshoot to the component level. This will save you an huge amount of money.The board could cost as much as $800 dollars. Scrivitron
