Ok...This Is Weird. A Storm Just Came In And Knocked Out Electricity Et Al. Hard To Do Any Testing. Don.T Thinl Its The Switch Because There.S A Media Room Behond The Set That Staus Pretty Cool. I Huess It Could Be The Lamp Bit It Seems Weird There Was No Evidence Preceding Failure.
As it turns out, neither of the two possible solutions you suggested seem to apply. Following my electrical downtime, I fired up my system and everything was working fine again. However, after about 15-20min of play, the system does what it did before...black screen and both leds flashing simultaneously. The temp in the back of the set is about 75 degrees. do you have another possible solution?
Are you certain the LEDs are not alternating their flashing?That would indicate a problem with a cooling fan or temp sensor.Here is the reference:Remove the lamp access door and locate the presence switch.It should be just inside the door, and activete it a few times with your finger.Best test would be to hold the switch down with tape.... and see if anything changes.Next we can go into the self check if you have the original remote? to see if it is throwing out any errors.
I can't display your graphic. My computer indicates no file. Anyway, i've taken off the access panel to the lamp and do not find anything that resembles a switch except for a hole in the front right that has a small 'band' that extends across the interior of the hole.The way the front panel is set up, there's a plastic 'rod; that inserts in the hole where the 'band' exists and would push it back . If that is the presense switch, I think it would always be activated by that rod. As a test, i used a screwdriver to replace the rod and started up the tv. It worked. So thien I drove a small screw into the 'rod' to extend its length into the hole. Then started it up...and that worked. Seems as though the real problem was in the switch, but it was that the switch had a marginal position for activation.
