More than likely the main board or the inverter is bad. However, the first thing I always look for if you're going to take it apart yourself is the power supply. If you see capacitors that are bulging then you have a fixable problem. If it comes to board replacement or having a repairman like myself solve the problem most of the time you get into costs that exceed replacement value. Not the price you paid for it but the cost of a comparable unit now. The model number you posted doesn't come up for me in our system but your description is probably a main board failure. The test I would do is to unplug the set. Then plug it back in after 30 seconds. Then turn it on and check to make sure you are on the right input or channel. Make sure the cable box,dvd player or antenna is hooked up properly. And once you have done all this. Begin to suspect the tv as the problem. One more test is to hook up a different television to the equipment that you use on the Broksonic and make sure it works. I hope this was helpful. Let me know if I can do anything more. Good Luck, Russmann.
Sorry it took so long to reply to this but I had service calls to run. If you want to start replacing boards the best way to get them is to Google the model number and description of the board. Then you will get a part number which you can use to see a picture of the board and make sure it matches the one in the set before ordering it. What I usually look for is the plug connectors and all the transformers are in the right place. You could also try to find the service manual first to get the part number but that adds an unnecessary step. First again if you are going to invest in boards hoping to fix this set the burden falls on you instead of a professional repair center. For instance, how can you test to see if they sent you a good board, and can you get a refund if you decide to bail from the repair. If you really want to do it right, than get a cheap test meter and check for shorted diodes and transistors with continuity or ohm setting. Look for bulged capacitors. Check the voltages coming off the power supply which are marked on the board. And if all that checks right, replacing the main board should fix it. This is the best advice I can give you.
