The tv has power , the volume comes on ,but no picture,just black screen. The red change lamp light has been on for some time,and it is still on

Ebay lamps can cause this as they are not originals also the balast supply, is gas discharge type, can fail.

Panasonic DLP TV Bulbs

Make sure its an original Osram or Philips bulb inside the housing. If its a cheap lamp it will act this way. If it is an original lamp, then you may have a power supply issue. It shouldn't affect your TV but you may want to try resetting the lamp timer by following the instructions that came with the lamp.

While pressing the VOL- button on the projection display, hold down the number 0 button on the remote control at the same time for more than 5 seconds.

This is a lamp issue. Reseat the lamp and if that does not fix, replace.

Hi,
Symptom shows Lamp is weak in result and causing restart of TV again and again. Your TV requires new lamp as per following part number...
A1085447A* LAMP BLOCK ASSY XL-2200U
It is available in Sony Accessories Store for $200 and replacement procedure is written in instruction manual of TV.

Always buy Sony original lamp for TV and avoid aftermarket / cheap lamp for TV safety.

My Sony lost its picture and had a flashing light. Unplugging for 36 hours solved the problem.

Its most likely an intermittent lamp. The lamp door is located behind the front panel. The front panel can be removed after loosening the two thumb wheels located on either end of the TV in the rear. Observe the light coming from the area around the lamp door. If you see that the light is going out, its the lamp. You can also access the self-diagnosis menu by using the remote control. Start with the TV off. Push the "mute", then the number 5 button, and then the volume down button followed by the power button. When the picture appears, the menu will been visable. If there is a failure with the lamp, or a fan, or many other areas in the TV there will be a number value to the right of the parameter that indicates the number of times the error has occurred.
