The rca itc222 model is in shutdown node. when the processor detects one of 25 different conditions that might present a saftly issue the it shuts the set down this is characteristic of a blinking front led light. this is an idication that the main fuse is ok and that the processor is receiving power. the wheese sound hower is charteristic of a blown horizontal ouput transistor and a possible bad flyback situation. there are other condition that cause this THere ribbon connectors between boards that can be loose. if it was in the shop the first thing i would check would be the horizontal transistor. then we as technicians have a computer interface that we use to check error codes much like automobiles, As always be careful this television retains up to 320 volt even unpluged

Picture is really light in color screen is white


It sounds like you have bad solder joints in the tv. If you resolder the boards in the tv, it sounds like it will be fine. When you are slapping the tv, it is temproarly making contact again and fixing the picture..
