Push power buten no picther no sound
Hello
The fault of your tV is with its power supply section. There is a power regulator board inside, which converts the AC power we give to lower DC voltages, which in turn used to supply different sections of other boards. With a dead set, it will be difficult to say which part of it has damaged. You must ahve thorough knoledge in elelctronics, and experience in servicing switching type power supplies [SMPS] boards. In most cases the power supply is replaced with an other one as card basis, becuse, most of the components it it are very difficult to get from open electronic spare part market. You can get this board, from the authorised service center for RCA at your town. If you have enough knowledge and confidence, go forward, and check the power retulator board for faulty components, and replace them if they are available. If not, get this set repaired, either by the authorised service center for RCA at your town, of by any well experienced service technician. OK.
