My first question post. I have been having no luck in determining the fault causing my television's remote control not to function. About a month ago the remote ceased to function. I replaced the batteries which did nothing to solve the issue. I opened the remote to look for any obvious damage. I did not see any burn marks and all the copper tracing appeared to be intact. I reassembled the remote and attempted to use it again. To my surprise it worked. But five minutes later it ceased functioning again. I decided to just purchase a universal remote and go about my channel surfing. Unfortunately, the remote I purchased would not program to the TV. I returned the remote and tryed a different brand with the same result. In retrospect maybe it wasn't wise to purchase a TV/DVD Player combo at what seemed like a really cheap price. I mean it is RCA which I think is generally considered a good brand, but I haven't even had any luck with an RCA brand universal. Well, next I tried opening it again and wiring a power supply to the PCB without the case. I manualy completed the power circuit path and the TV came on. The same for the channel and volume and number circuits. It worked for about five minutes again and ceased function again. I gave up for about an hour then tried again. It worked again for a few minutes and then stopped. I have been unable to get it to work since. My suspicion leans towards a component fault, however I'm somewhat inexperienced with electronics and don't know where to start. I decided to post to see if someone might have some useful advice. Needless to say manually changing channels and other controls is extremely annoying. I also don't have access to a lot of functions anymore since they are only accessible throught the remote. I appreciate any help in this matter.
