The clicking is the Stby relay. Your fault is on the PSB. Change the 1000 UF 10V Capacitors PSB with no more than 8V above the current rating. There are two of them side by side. Yuu can get new caps at radio shack or frys rtc. Get polar electrolytic caps with 105 C heat rated.

need some help email me

The clicking is the relay -- check the fuses on the supply board and you might need to purchase a new board

I have 50 in plasma phillips magnavox 50mf231d-37, will not come on red light flahses 4 times

this is some info that some one else had found

get a memory stick( flash drive) and up load their soft ware from their site. I plug the stick into the computor and uploaded the software. I then plugged the stick into my TV on the side. A screen came up and the software loaded on the TV successfully. The red light then turned to green. However, I now have to unplug and plug the TV several times for it to turn on. It works fine but once the TV is turns on, but when I turn it off and it cools for a while I have to repeat the same proceedure off plugging and unplugging
