Re: RCA HDTV Cabel Connection
HD doesnt come over the coaxial cable into the TV. It has to use HDMI, composite (5 color RCA cables) or DVI. they can all be soldered back on if you ripped one out. easier to use another input if you have multiple formats back there.

My friend had the same problem. There is some display bulb that is on its way out. They aren't cheap. Find a 2nd hand TV parts/repair shop, They usually have cheap used ones from discarded units, and will know what you need!
This is due to a faulty convergence power supply or voltage supply to the convergence board, first thing to check is the deflection board this the board to the right of the unit look at if from the back.
Check all connection on the flyback and resolder is any cold solder joints are found. Also there are tree micro fuses the may of blown if there are any bad connection around the flyback.
My tv is relatively new, but the bad thing is that I had an old; big screen tube type rca model; home theatre, that was heavier than a car, and it went out, due to the cracking and popping sound, off sometimes, and back on.
What is strange is the new tv now, the hdtv, light weight, about five years old, is doing the same thing. Actually, now, the power will not even come on. The lcd green light in the front goes on and off.
Take no offense, but I thought I would not have these problems anymore. What do you suggest?
you eather have a bad solder connection or a part overheating...this unit has a processor that generate error codes that technician with a special computer interface can read....this is where the troubleshooting begins...first thing a tech can do is check make sure all cables are securely plug in.
