Got my hands on an relatively unknown TV brand about two weeks ago.
I certainly hadn't heard of it before.
Previous owner didn't give a description of what was wrong and when I got it the back cover was already off.
I put it on the back burner until I had so spare time to look it over.
Today was that day.
I plugged it in and was surprised to see that it started up without any issues.
This is an older TV and the most modern video input that it has is DVI.
I was scrambling to find a DVI connector or adapter as I haven't fooled with that format in quite some time.
Eventually I found a DVI to RG232 adapter from an old apple computer I had laying around.
I connected it and found that it did indeed received video signal via the RS232 port.
Excellent! So what was wrong with the TV??
After more digging I then found a DVI to DVI cable and tried the same thing but there was NO signal detected.
I used a car backup camera with an S-Video connection to confirm that the composite inputs worked as well.
So it seems that the DVI port was not working and the previous owner decided to get rid of it.
Looking over the TV I was sort of impressed with its build quality (for a brand that I have never heard of).
I discovered through some stickers that the panel was actually manufactured by LG.
The capacitors are all puffed out at the top and would need to all be replaced.
While this TV is built solid and could last another 30 years I just want to use it to practice my troubleshooting and repair skills on it and then possibly harvest it for parts.
It is VERY heavy (32kg or 75lbs) for a 42" TV and coupled with the fact that it has no modern inputs it wouldn't be much use in today's world (someone please correct me if I am wrong on this).
I haven't tested any components yet and simply took photos for you all's viewing pleasure.
So where should I start troubleshooting the DVI port issue?
