Hi Im hoping someone can give me some guidance on my TV, it will not turn on. The symptoms are the led on the power button will illuminate when turned on and will make a beeping noise, but I dont have any picture or sound.
There are many things that can cause such a symptom. These sets are not easy DIY projects. Look for someone experienced on these sets in your area and get an estimate, or you will have to provide much more detailed troubleshooting information for anyone to do more than make a wild guess.
Step by step troubleshooting is beyond the scope of the forum. We try to provide general information and a few trivial symptom-repair relationships. Generally, one starts with observation of what is working and what is not, and makes measurements of the basic parameters like power supply voltages. Again, without some TV repair background, these sets can be difficult and are often not likely a good DIY project, aside from something like a convergence repair.
OK, I tried replacing the power board and it is the same issue. I read somewhere that the beeping is a sign of the circuit pulling to much current, but none of the fuses have blown. I did forget to connect the power input to the large sig pnl, and the beeping had stopped. I am currently trying to go through the schematics nice and slow, and reading the convergence thread again for some ideas.
