TV flickers then turns off. Standby light continuously flashes red. All fuses, cables and batteries checked and no problem with sound.

The T con board controls the picture. It has a problem and needs to be replaced. You can get the board from:
TV Parts Universal TV Stands DLP Chips ShopJimmy
You can replace this board yourself if you're not afraid to take the back off the TV.

My panasonic viera 50 inch plasma wont turn on. When i turn it on a red light comes on and nothing else

I had the same problem with a Panasonic Viera Plasma TC-P50S3 with 14 flashes. I used an ohm meter tocheckcontinuity of the boards inside, starting with the power board (power to TV off). Check YouTube for videos on how to do this. The SC card showed a fault (It was reading close to zero ohms on both pins. I could find no one who supplied SC boards and could only find repair kits. Repairing a circuit board is outside of my ability, time and tools. I found a place online to send the SC board in for repairs. $65 plus shipping. I was getting $350 "ballpark" quotes from Panasonic authorized TV repair shops. If none of this works for you, there are TV salvage companies who will pay you some cash and pick up TV from you. You can also sell it on craigslist for salvage parts or part it out separately. The various boards seem to cost around $100 each and you likely have four or five in your TV. At least for my TV, the parts don't seem to be out there, so there is a demand for the salvageable parts.

Your TV is showing symptoms of power supply failure. It needs to be repaired or replaced. The remote has nothing to do with the power supply problem

Stand by light flashes red on powering up with remote and the green light flashes approx 15 or times before the screen illuminates.

thats pretty normal, it takes a good second or two to warm up and the display to turn on(at least0, you get the green flashes as you hold for on, 1 sec is a long time at times, lol, be patient, no problem with your tv!
