Question about RCA D52W23 52" HDTV CRT TV
The tv was working perfectly fine until i was transporting it and it took a little spill in the truck. When I got out of the truck it was leaning on the side of the truck bed with the plastic above the screen. So thats where the impact was. When I brought it inside the house the tv starts buzzing in the back as soon as you plug in the cord. The tv does not work anymore. The buzzing comes from around where the cord enters the tv.
Without disassembling the set (removal of the back), there is no way to determine what might have been damaged and further operation without finding and correcting the problem may could cause further damage and may be unsafe.
In many CRT sets, the main board is not very secure and is normally held by slots either side of it.
It may have been jarred out of the slots and shorted something on the trace or component side.
If would be safe (unplugged of course) to remove the rear housing with the 4-6 screws holding it and at least visually examine it inside; the problem may be easy to spot and correct.
However, any kind of sharp shock to the CRT (picture tube) may have misaligned it inside, making the picture geometry and color alignment impossible.
If your set is not compatible with the coming HDTV standard, you might want to consider replacing your set. I suggest though, that you take a look at this article describing the pros & cons of CRT TVs:
CRTs or not?
As a service tech, I would also suggest you poke around here (Fixya) to see how others are faring with their various kinds of flat-panel and big screen sets; way too many are dying like flies.
