Well, now I did it. 52725, manufactured in '04. Replaced the bulb about a year ago. Recently I've been getting some weird video noise (bands of static), so I decided to tear my baby apart and have a look. Other than being totally filthy inside, everything looked good. Believe it or not I couldn't find a single swollen cap, let alone any that were leaking. So I went about my business and reassembled everything. Demated all my connectors and cleaned all the contacts before reconnecting.
Finally got it all together, and now I have the BGLOD. Must have missed a connection in there somewhere, though I can't imagine how. Stranger things have happened.
Guess I get to tear it apart again.
Well, took it all apart. Only thing I found was that one of my ribbon cables wasn't completely seated. It also looked like I crimped it on one side (must've pulled on it when fighting to get everything back together). Reassembled, and there was the BGLOD again. Thought I was going to have to hunt down a new ribbon cable. Let it sit for a few hours, came home, and it was still blinking. A quick reset, and whaddaya know...everything seems to work again.
Still have a fairly poor picture with random video noise, so all my work was for naught. Now I just gotta figure out whats really wrong.
**UPDATE PART DEUX**
BGLOD is back. Turned off the TV to put everything back together. Had to remove the filter cover, which triggered that switch (had a flashing orange light then). Got it all back together and the damned green light is there mocking me.
Cannot get this damned thing to fire up. Wondering if that damaged ribbon cable may have an intermittent short or something. I'd like to replace it, just to check. Unfortunately, I can't figure out what the part number is (let alone a place to order it).
Can anyone help? It's the white one at the middle bottom of the pcb.
After sitting all night with the BGLOD, another restart this morning and the set fired up. Been running strong for half an hour now. Fingers crossed.
