Well I have a TV repair person coming to see the TV soon. I also ordered and have received a replacement bulb, at my own expense, just in case it is the bulb. They want $300 + Tax in Canada for the bulb and I got mine at around half that through an online source.
I just don't understand how the bulb can be the problem. I took out the one that was in there and blew out all of the dust. After looking closely at it you can see that it literally is nothing more than a bulb. There are no electronics invovled. This is why I cannot understand how the bulb can be the culprit. It either works or it doesn't. If it works, which it does, then the problem must lie somewhere else. Not to mention, what was the point of putting the Replace Lamp LED on the front of the TV if it never lights when the bulb is the problem?
I honestly wonder about why every repair company that I was forwarded to always said first and foremost, that it may be the bulb? Even after describing that it still works they continue to warn me. I swear that they all try the same technique to just make a quick bulb sale. I think Sony really needs to answer to this, as to why I need to replace a bulb that still works and it is not covered under my warranty.
