Mitsu WS-65517 won't power on (NOT BGLOD!)

Hey everyone, I picked up a Mitsu WS-65517 for free on craigslist and am trying to get it up and running. Here is what I know so far:
-When I plug it in, it goes through the normal 70-sec bootup.
-after that, if i press the power button, the green light will blink a few times and the set does not power on.
-after this has happened, the remote and front controls seem unresponsive and I don't get another light blinking.
-The error code shows "12"
-resetting it doesn't get me anywhere
-DM fan runs when I plug in the set
I took it apart last night to check the caps, none were bulging so I thought i would hold off on replacing them for now. When I put it back together and plugged it in, it powered on, a very dim blue. I waited about ten seconds and pressed the device button on the remote. It immediately shut off, and doesn't power back on. I haven't been able to replicate what happened, either.
Any suggestions?

Ok, so I started messing with it last night, and I was able to get it to power on for short periods of time. Here's how it went:
-I plugged the tv in, green light blinks for 70 secs
-I press the power button, it blinks a few times and nothing happens.
-I get mad and press all the front controls a bunch until the green light starts blinking again.
-when it stops blinking (after about a minute, maybe i was resetting it somehow?) I press the power button on the remote and it turns on.
-The screen is all blue, with the writing in the top left for "Ant-Main" or whatever.
-It shuts off after about 30 seconds.
It seemed totally random as to when it would work and not work, but never for very long.
The last time it turned on last night the screen had strange lines like in this photo (the photo isn't that great, the whole screen looked like the top part of the photo, there was no black).

I'm the HighDefForum member that has been sending out the repair instructions for the BGLOD problems for the last 2+ years. Recently I came across a company that sells instructions and parts for numerous TV brands/models for their typical problems: their name is TV Repair World. I've spoken with the owner, and they seem to be more than willing to speak with folks such as yourself to counsel them on what the cause of that problem might be, and will sell you the parts and instructions for the repairs you need to make.

Contact them at www.tvrepairworld.com, or give them a call. Their phone # is at that website.

Hope this helps. Good luck - Paul

Ah! A picture is worth a thousand words indeed!
That looks like a horizontal frequency/sync problem to me. The error circuitry detects the problem and shuts it down.
No doubt the 12 error is H deflection. I'll look it up tomorrow if I remember.

Hmm, Error 12 is "no error," so I'm not sure that helps...or maybe it does. Your theory is compelling --maybe there's just not an error code for that malfunction?
I don't seem to have the crazy lines problem anymore though (at least not yesterday)...

Anyway here is Day 3:
I "tricked" the tv into working on a somewhat consistent but NOT fixed sort of way. When it goes through it's 50-sec bootup, if I continually press the power button on the remote over and over, and stop pressing it before the light stops flashing, the TV will turn on. It also will stay on and let me cancel out the netcommand junk that comes on right after powering on. It will let me change the volume, and sometimes the channel. I can go into the "menu", but if i try to go into any of the submenus it becomes unresponsive and shuts off within 10 seconds. I can't change "devices" either or it will shut down. When it shuts down it goes into boot mode again and I can repeat the same procedure as before and it powers on. Some of the buttons on the remote just make the TV go unresponsive and I can't do anything else to it but unplug it and plug it back in.

I'm also curious, the service manual says the boot sequence is 70 seconds, I'm not sure it means anything but I timed mine and it is only like 52 seconds....could be a red herring though...

I hooked up a cable box to it last night and watched it for a good hour with no problems.

Ok I have full functionality as long as it is using one of the RCA inputs. The problem lies when I use one of the coax antenna inputs... Once I turned off those inputs in netcommand the tv works fine. Good thing I was only intending on using it as a gaming tv :)
