Hi

For past couple of days, My 7 year old Samsung HLR5688W Dlp tv would turn off by itself. The tv would give an error code with a Exclamation triangle and a bulb symbol under it. Any idea whats wrong with it and what part do I need to replace.

I have posted a PIC of error symbol to my post.

Please let me know

1 time the bulb has been changed, around 2 year back

Thanks
