Question about RCA D52W20 52" Rear Projection HDTV-Ready Television
I`ve had no dealings with these particular sets but have you tried different inputs and sources, DVD`s SKY BOX etc?? It could be a faulty scart lead or even a faulty box. Try plugging them into different sockets see if this improves the situation and try disconnecting scarts and plugging devices directly into the TV. If no different, If you turn the contrast and brightness down, does this improve?? Yes?? Is it One colour that`s blurred? Yes?? That tube could be getting tired, or is it all colours that`s blurred equally?? Yes?? It could all the tubes getting tired equally due to them being the same age as each other or it could be the LOPTX (High voltage transformer) or Hstat (Splits the high voltage evenly between the separate tubes). Located on the LOPTX and/or possibly on the Hstat is a control that adjust the voltage to the focus anodes within the tubes, sometimes these get dirty and if you turn them one way then back again, could clean the control temporarily. PLEASE DO NOT POKE ABOUT OR TOUCH ANY PART OF THESE COMPONENTS UNLESS YOU KNOW WHAT YOU ARE DOING. Some projection sets run at 40.000 volts. I hope this is helpful, Ian
