Seems this thread still gets a post every once in a while, so I'll give it a shot:
I have a 51 inch WS550. Bought it back in 2003, I believe. It has been a trooper- through 2 moves and never had one problem. Lots of space and am more that happy with picture, so upgrading to a flat panel has never been a need.
I was using my PS3 as a Blu-Ray player. I had been using the PS3 HDMI output, with a HDMI-to-DVI cable into the set, no real problems, but I did notice that when on Input 7 (DVI input), I could hear a VERY faint 'beeping' sound coming from the set - probably once every 5 secs or so (this was not present when on any other Input or when the PS3 was off, so it was definitely coming from the TV). The beeping was so faint that any audio would drown it out, so it wasn't really a problem though I thought it was probably an indication of an eventual problem looming.
About a year ago, the PS3 took a crap and I decided to just get a regular ol' BR player. Went with a basic Samsung, and again used its HDMI out to my TV's DVI in. Worked well for about 4 months then noticed that, intermittently, I would lose the video on the TV, though the player kept playing (audio was present, which I got through my Receiver). This increasingly got more and more frequent so I sent the BR player back to Samsung. They replaced a board and sent it back. Worked fine, for about another 3 months, then same problem started again. Sent it back to Samsung. They couldn't replicate the problem (even though it was intermittent). Got it back, same issues. Replaced the HDMI to DVI cable - still intermittent problem. Whenever the video goes out, I can connect regular old composite video out and it works fine. I actually borrowed a different BR player from someone and using it, the same intermittent problem (loss of video) continues to occur. When the problem occurs using the BR player's HDMI out, I switch it to use Component output to the TV's component in and it works fine. So, it seems that the TV's DVI input is the problem.
Now, I know many feel that there isn't a lot of difference between DVI and Component, and I only need 2 component video inputs (one for my cable box, and now, one for BR), so I'm not in dire need of the DVI input, but I am a bit OCD and would like to fix it if something easy/cheap.
So, after all that, my questions:
Has anyone else experienced this or have thoughts on what the problem is?
Any thoughts/knowledge on fixing?
If I decide to attempt to pay for service - do they do this in your home or send it away, and any experience with service costs (parts excluded)? Obviously an old TV like this only has so much value so it has to be economic to pursue.
I am willing to attempt some DIY stuff, but probably nothing too crazy. When I look at the DVI input on the back of the TV (I haven't taken the back off yet), it would seem the DVI input is similar to a computer card, which maybe fairly straightforward to replace (plug and play?).
Thanks a TON for any feedback/thoughts!
