Hello. I have a Sony Grand Wega Model # kdf-50e2000. I replaced the lamp, but the Standby light flashes red 3 times. I referred to the owners manuel and chatted online with sony support, but I their suggestions did not help. I checked everything to make sure it was properly installed. I checked the lamp, the lamp cover, and the lamp door. When I turn on the tv, the fan starts and runs for 2-3 seconds, then it shuts off and the standby light flashes red 3 times. I took off the back panel of the tv set, and checked if the lamp cover connects to the sensor properly. It does. Do you think that the fan on the side of that unit could be the problem? It starts then shuts off after a couple seconds. The Standby light turns green at first, then after everything shuts off, it flashes red 3 times. It looks like it is easy to replace. I don't want to call a technician because they want to charge $99 just to come see if they could diagnose it.
A fan error would result in the light blinking 4 times each. The 3 blink code is only for the lamp and lamp cover. Was there an error before the lamp was replaced? What were Sony recommendations? I would start with removing the lamp cover, and the lamp and then install the lamp again and put the lamp cover back on.
Dusty J, Thank you for your response. Sony's recommendations were the same as yours. My husband and I repeated those steps about 10 times altogether. Then we took off the back panel to see the lamp cover connection at the sensor. The connection was really good. Is there anything else we can do? Or could the lamp have been a bad lamp? I got it from discounttvparts. The part number was correct: XL-2400.
Thank you very much Dusty J. I also tried to put the old lamp in to see if it would turn on, but that did not work either. But, I fixed it! :))) The problem was the Pcb assy (or board) Sears part number A1177123A. It is the sensor that makes sure the lamp is properly installed. It may have moved with the heat from the lamp. I took apart the back panel of the tv, and I moved the circuit board to see if I could see any other parts that might have a problem. What I saw was that the new lamp (and the old lamp), did not push the metal connector far enough to make a connection on the sensor. I put a few layers of electrical tape on the part of the lamp (plastic part) that pushes the connection to the sensor. The tv works like new :) Thank you for your help. I really appreciate it.
Hi Rachel. I put a few layers of black tape on the black box (housing) that holds the lamp. From the lamps right & left sides, it is the corner located under and to the right of the lamp. If the lamp was facing you, then it would be your left bottom corner. It looks like there is a little lego piece on both corners. Place the tape layers over that corner. Hope this helps. Also, try to get out as much dust as you can. The back panel is easy to take off. It's about 10 or 12 screws. You could take a lot of dust out that way.
Stephanie, I had the same problem and if it wasn't for your posts, I would've had to shell out $200 to get my TV fixed. There were a few different things I had to do and I'll explain here for those who may run into a similar problem: -I purchased my bulb and housing from Amazon -When I replaced the old bulb/housing with the new bulb/housing, my TV didn't work -red light on the front flashed three times telling me the lamp wasn't installed correctly -Switched out the new with the old, and still had 3 red lights -Pulled off the back panel like Stephanie did and saw the housing wasn't reaching the sensor. Put electric tape on the new housing and tried again...nothing! -Put electric tape on the old housing and boom...TV came back on! -Thought I had bought a bad bulb, but it was just a bad housing. -Replaced the bulb in the old housing and VOILA...TV came back on! link to replace just the bulb from housing: http://www.youtube.com/watch?v=HiAgo00-URE Thanks again Stephanie, I wouldn't have made it as far as I did without your posts.
