If it’s a CRT set, sounds as if the blue gun on picture tube has gone out or carboned up. It could also be a problem in your video section or the board on back of picture tube where it plugs in. You could try to use a good electronic cleaner and a q tip on the socket pins on the back of picture tube. UNPLUG IT and don’t touch the wire or connector that goes to the top it the crt tube! Allow it to dry for at least two hours before you plug the board back on the tube. BE CAREFUL!! Go easy when unplugging and plugging in that board! If this doesn’t help you would need diagnosis by a qualified technician.
Same issue with - Panasonic TH-50PX70A , power UP with red standby, then power ON by remote - only Gives GREEN led blinking 35-40 times, followed by solid green led with no no picture no sound.
>> Solution; unplug Plasma from AC 10-15min, then plug in & power on to Red standby led,, At this point - Power ON tv while holding down both -Volume Down and F (function Select) buttons (front panel door) at the same time turns picture ON,all ok.
When u turn the tv on,u hear alot of clicking?That mean the Ballast that help the projection bulb to work is dead.Change the Ballast,might as well change the bulb too.U don't know what is the condition of the projection bulb in.
not a solution but i have a 50gx30b doing something similar, no picture no sound, 3 green leds are lit up on the main board and then one red led lit up also on main board, front panel red led stays on for about 30 -50 seconds and then it all shuts off, I then have to unplug and replug to get the same results.
Does Tube Light up? with TV on Look down into Tubes and see if picture is clear or you can bearly see picture or not at all Your Projection fliuld may need changing Ive seen where tubes are still lighting but No picture showing inside tube---- Bad Coolant Fuild Call Mats for fuild and for Tube if thats what it is Call Encompass 1-800-638-3328
when You changed the bulb you have to reset the bulb timer , that why the light is flashing red , look at your manual and reset the timer , and the picture , changed bulbs myself before i found what the problem was ,
