Did you ever get your Philips fixed?

that specific flashiing is the software in the computer, the television has inside

you need to go to the philips website and download an upgrade software repair it is free-- put it on a thumb drive without any other things on it---- the television ,must be on to install --- turn it on with the remote and then insert the thumb drive-- the television will run a scan--- then turn off television and wait a few minutes-- turn it back on with the switch on the side of the unit-----

the power problem is something else--- the power board sounds like is going bad--- a new one is around 300-400 and a rebult unit is around 100 --- you can find them on partstore.com

this television is poorly built -- when you get the new board it is easy to install -- before ordering a new board -- check the fuses on the board-- there are two fuses -- one is 1amp and the other is 5amp -- both are slwo burn fuses

I had the same problem with the same model. I took off the back of the television and checked the two small fuses. They were fine, unfortunately. So I bought the refurbished power board from Best Buy using the part number that I found on the web. Swapped out the board and the TV works fine. Now I need to know what to do with the old board. I feel badly throwing it away since it is probably some simple part.
