I have a neighbor friend with a KDL-40EX500 he's had for about 5 yrs. The picture one day while watching TV just went increasingly dimmer then black. It now exhibits the 5 red blink code and won't turn on. I've read this means a bad T-con board.
I've read Sony doesn't make them anymore but I've seen them ranging from $15 to $25 described as new or refurbished, mostly on eBay. The part looks very easy to install and I'm not at all opposed to refurbed, as sometimes they have better than stock parts.
I once repaired my old Sony Trinitron with a degaussing relay bought at Sony, whom said it was a better part than the original. That was 7-8 yrs into the set's life and after that it lasted a total of 20 yrs. Sometimes these techs that sell refurbs source pretty good parts.
Anyways, I'm trying to convince him that even if he wants to look for a longer lasting TV, like a LG plasma or something, it's worth it to get this cheap part and let me install it just to hold him over until he can afford another, and time it to the big yearly sales.
The only thing is, I'm not 100% sure this code most assuredly means bad T-con, as I've only seen a couple techs verify it. Supposedly 6 red blinks means bad backlight or panel, and 5 means T-con though.
What say you guys? Has anyone here had to deal with a 5 red blink code on the EX500 series?
Thank you, sorry if I interrupted the topics being discussed. Need an answer fairly quick though. This guy likes watching TV quite a bit in the colder months.
