If you are getting audio but no picture it could be a bad panel or the digital board. Ensure you have all of your connections properly seated and if you're still without video, I'd look at getting a service center to take a look at it.

The 42DPC85 is erroneously refferred to as a television when it is in fact a monitor; ie. it has no built-in tuner. You will have to connect a VCR to the monitor and use the VCR's tuner for cable or antenna viewing. You may notice that the monitor does not have any 'channel' buttons.
The remote that comes with the monitor has 'channel' buttons but they are for external devices.
This is a common problem on these plasma TV's. The problem resides inthe high voltage boards known as the X and Y Sustain boards.. You canpurchase them here for a very reasonable price: http://www.discount-merchant.com/Y-SUSTAIN-FOR-42-PLASMA-TV-PN-6871QYH036A-p/sku9510.htm
The above link is to a Y-SUS board. The X-Sus board is often the 2nd cause of failure and can be found here: http://www.discount-merchant.com/X-SUSTAIN-6871QZH041B-6870QZE017D-6871QZH052D-p/sku9509.htm
Totest which board is failing, you need to check voltage input to theYSUS board first... Input should be 120V from Power supply, outputshould be above 250V.. Do this test with XSUS disconnected. IF 250+Vexists, then XSUS is damaged. If not, then the YSUS is the faulty part.
I bought my Toshiba 50HP66 50" Plasma a little under 18
months ago and about four or five months ago it began to act strange.It would put a block of characters on the
screen that made no sense until I would unplug it and and restart it.Then it would act normal for awhile and would
just need a reset every so often.I was
out of the 12 month warranty so I just put up with it.....until yesterday.I was watching the TV when out of nowhere, I
heard a really loud POP....and then the screen went dark.I went ahead and bought a new Sony LCD screen
and was going to sell this for parts online.I troubleshoot electronics daily so I thought I would purchase a digital
copy of the service manual and check it out.After I downloaded it I noticed that this is very common with plasmas
(this exact failure) and only on the LG boards.I scanned my handy dandy service manual and found out that Toshiba was
using these same boards along with Zenith and some others.The difference is all the other manufacturers
honor their product and replace these boards even when the warranty has expired
so I called Toshiba and tried my luck.Even though I've found many postings of Toshibas failing and hundreds
and hundreds of the exact same board failure...Toshiba claims to have never heard
of it.I informed the "Customer
Support Supervisor" of Toshiba that I would be willing to post this on a
few websites and have other customers contact him to inform him of this issue.He was fine with it so here is his contact
information so feel free to let him know your Toshiba plasma went POP as well.
Dave Thompson and let him know.
