TV Repair Questions? Ask a TV Technician
Thank you for asking your question on JustAnswer. The lights indicate a problem. They are there as an aid to the electronic technician to help them diagnose the problem. The problem is not fuses. Be careful when the back is off the TV. There are voltages inside that can harm you. Heat is the number one enemy of electronics, and these sets operate hot. These sets are assembled using the wave soldering process they are known for having cold solder connections. This model of TV has over 3,000 parts which include millions of transistors inside the integrated circuits. The capacitors will change value, leak and become defective. Resistors will change value and burn. Integrated circuits and transistors can go bad. This can cause other components to become defective, which can have a domino effect and cause other parts to fail. Replacing one defective part may make the TV operate for a short time but the part will fail again since if the parts that caused the failure to begin with are not replaced. The only way to know for sure what is causing the problem, which parts that are no longer within factory specs and for proper repair all the electronics must be diagnosed by someone with the correct electronic test equipment and the skills to use the test equipment. I wish I could tell you there was a quick fix or button to push that would fix the TV but that is not the case or the solution needed to get the TV operating correctly. A small TV repair shop will often charge less for the repairs than a large repair facility will.
If you wish to repair it yourself what type of electronic training do you have? What type of TV test equipment do you own?

Please do not accept the answer unless you are through with the questions, are 100% satisfied with the answer and feel you can leave positive feedback. The high voltage diverter box is one of the several problems I believe this TV is having. The estimated useful service life of a rear projection TV set is 12 years. Not many of the RCA TV make it that long. I am not one to toss things out that can be repaired but there becomes a time when it is better not to keep spending money on something that will never be as good as the new technology. I hate to see you waste the money on a TV that is going to cost way more than it is worth to have repaired if it can be repaired and then have it fail again in a couple of weeks. RCA is not known for manufacturing a long lasting TV.
