Question about Hitachi 53UWX10B 53" Rear Projection Television
The most common cause of no video is due to the vertical output section failing. If this is the case the TV will still have sound from the program that the TV is tuned to. If you do not have sound the TV may have a main power supply problem. To find out if the high voltage is still operating you can remove the rear cover and turn the TV on to see if the filaments in the picture tubes are glowing. A no high voltage problem will require some basis troubleshooting of the main power supply. In many of these TVs I find that the horizontal output transistor will short out and this will shut down the main power supply.
