SOURCE: Power light blinks 10 times

You have the same problem i have. My Tv just did the same thing 3 nights ago. I unplugged the set, and let it sit ofr about 6 hours, and then tried it again. It turned on and played, but repeated the problem after about 20 or 30 minutes. So far all my research has led me to believe that its a power supply issue. Problem is, there are 5 boards in the tv with seperate pwer supplies, and the 10 red flashes indicate that its all of them. :-(. Im shopping for a new TV, and It wont be a panasonic this time.

SOURCE: I have a panasonic TC-P50ST30 and viera link will

Unfortunately, your charter HD DVR cable box is not a Viera link device that is compatible with the TC-P50ST30. Viera Link only works to control Panasonic HDAVI devices that are Viera Link ready (and that use the same Viera link coding) when using the HDMI cable. Thus some Viera link devices of different generations will not work with the same Viera link remote.

The manual for the TC-P50ST30 is available here: http://service.us.panasonic.com/OPERMANPDF/TCP42ST30.PDF . See page 32 for details on the Viera link controls.

I wish that I had better news for you. However, you will need to use separate remotes for your cable box and the TV.

SOURCE: Have a RCA flatscreen model # L40FHD41, blue power light comes on and stays solid but I don't get any picture or sound. Screen stays completely black as if it doesn't have any power at all.

Other than checking all the connections going to it for signal it is likely a shop repair.

The nature of these sets is someone must open and inspect them and check for voltages missing.

At that point it becomes a guessing game---try the boards (purchase them) and see if a bad board.

It is always possible the front screen unit or display has failed which is fatal cost wise.

You have to weigh the cost of repair, age of set and cost of replacement in this.

The only way anyone can KNOW which board is bad is to actually remove and replace it----most shops look at it and shoot you a high estimate.

let me know if you have questions.

Need to download manual for Panasonic Viesa TCP50ST30


Do you mean the Panasonic Viera TC-P50ST30? The manual is available from the manufacturer on the product page: http://shop.panasonic.com/support-only/TC-P50ST30.html . Scroll down past the Firmware, Tutorials and Specifications sections. The direct link to the English version of the manual is http://service.us.panasonic.com/OPERMANPDF/TCP42ST30.PDF . (You will need Adobe Reader or a similar program available to read the manual.) The English version is the second link in the Owner's Manuals and Documentation section.

I hope this helps.

Red flashing light 7 times


These blinks (flashes) are fault indication. By the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit stage inside the TV. Count the blinks occur at one time switch ON, carefully. Do it once again, and make sure about the number of blinks. If the flashes are continious, non-stop, the main system control IC should be suspected. If you wish to get more details, check the site linked here. It has blinking codes detail to many brand TVs. Pull up older posts. Electro help . Check the site in 'Mosaic' view. It will make search easy.
