Question about Televison & Video
I have a 1994 rear projection RCA TV ModelP46727BA that does not have picture or sound, can you help?
ONE: This is an RCA set. Not a good thing - in my humble opinion. They are not a reliable brand.
TWO: The set is old enough that you should always keep in mind the question of repair or replace. Since it is an expensive set, it should return the investment to you; on the other hand, if the cost of maintaining it gets out of hand it would have been better to put that into a new set with better prospects. You have had transformer repairs done to it which is not a good sign; meaning that the possibility of other failures is great.
THREE: SO, lets now consider the symptoms of your set. The fact that cable channel guide data is showing on the screen means the basic video system is working. That means the power supplies and high voltage are in place.
FOUR: You could be in video input and there is no video and the set is working just fine. So, we must verify the cable box or cable wiring is giving you the right signals. The best test is to switch the tv to video in and play a vcr or dvd through the tv. If you are getting full picture and sound then the tv is likely not at fault.
FIVE: If you have another tv in the house, try connecting it to the same cable wiring to see if it receives the cable programming. If not, then the problem is wiring or cable box. If it does, then the rca may be at fault.
With these checks above you should be able to determine whether or not the tv is at fault; wiring or settings on the tv. Then take the appropriate actions. If the tv is truly at fault, you will need a repair tech to look at it, again.
You know, I have seen a case exactly like this and the problem turned out to be a short in the cable coming out of the junction box on the wall. I opened up the box and found a short against the metal box; moved the wire around and cleared it, put some insulating tape on the end of th cable and it worked just fine.
If everything is fine then the problem is with the transformer.It is blown up and u will have to call a technician to get it repaired.
