My set was turning off after a while by itself. I thought it was something run with the lamp. I took it out. It was working when I took it out. Now, that I put it back the lamp light comes on, at the on off swtich. What did I do wrog by taking it out.
Mine did the same thing , it finally didn't come back on , it was the power supply , i put a power supply in , made sure the light door sensor was in the down position , then before powering up I did a hard reset (hold the power button down for a minute until you hear a beep.

Yes, there were and are known issues--"lamp door not properly closed" means that but something else.
What happens is door is warped from heat from lamp----with door off set will not function due to the safety switch----want to know if switch/door are the real problem?
Engage switch with something not metal and try to turn set on--if it and lamp come on do not look at lamp directly----do not operate with level bypassed and door removed as heat can warp the outer plate if no door.
If it comes on door is the problem---look at it edgewise---if warped a little the tab on back of door that engages the lever does not do its job.
If does not come on with lever engaged something else is wrong.
There was a recall that has ended regarding this---some were so bad they melted the lamp housing and even fused the front door of the lamp to the plastic around it.
i thought you replaced the bulbs from the inside, look on the inside for a plastic cover over the bulb recepticals, take off cover you should see the bulb sockets, twist 1/8 to a 1/4 turn counterclockwise,it should come right out,luck
5 blink indicates - AKB circuit (AKB), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. Also unit be in IK blanking, try turning up screen slightly.
Make sure your remote is totally away from the set.
Make sure the buttons on the set are not sticky
If both of those are ok, it's your E-Prom in the set. RCA's are notorious for this, not a major repair, maybe $75-100. The 8 leg e-rom is only about $6.00
I just purchased a replacement lamp off ebay and the TV is working fine now. Color looks better too (which I guess I should have expected). Search for "REPLACEMENT LAMP SONY XL-2100U" on eBay and look for seller "niosales". I paid $129 out the door. Their are other auctions for this lamp you can check out. Make sure you look at lamps that include the entire lamp housing, not just the bulb.
You need to check the lamp itself,sometimes they just blow up like a bulb does and if the lamp is good make sure all the fans are running and all compartments are close properly like where the lamp sits.Set needs to be unplug from the wall while you check.The wainting is not acceptable for 3 months.Let Us know if you need more information.
