    We had a power outage for about 2 hours and when the power came back on I got the FGLOD. Just enough to cool those ram chips. After seeing this post, I heated the 4 rams chips with a heat gun, plugged it back in and it booted right up. I think I will stick with the current fix until it gets worse or I find a service that can reflow it a for a reasonable price.

    Thanks for the tip.

    I ordered a reflow/reball station 5 weeks ago. It still hasn't arrived but it supposedly shipped this Monday.

    I have at least two TiVos that need motherboard repairs. One with the FGLOD and another with what I suspect are failing solder balls beneath the processor. What's interesting is that the latter has problems when running warm, the opposite of the FGLOD TiVos.

    I have a big pile of broken electronics that I need to fix with the reflow/reball station including some vintage HP calculators and one of my car's smart key fobs. I'll be doing the repairs in ascending order of difficulty so the TiVos will be serviced somewhat near the end.

    Interesting that this thread showed activity again, right when I needed it. I decided to upgrade my 7 year old lifetimed TivoHD with a WD20eurx drive over the weekend. A side note ... thanks to all who post their experiences upgrading, you were all quite helpful. Specially, the "run as administrator" under Windows 7. After I reinstalled the drive, I got the flashing green light and nothing else. Based on what I read, I just kept the Tivo plugged in and tried restarting after 3 or 4 hours. Came up perfectly. The next day, I lost the ability to see live TV (could change channels, but just got gray screens). I restarted again and all has been fine since. This Tivo is mainly a backup unit, so my game plan is simply to see if it stays working without doing anything else. My "old" eyes didn't see any bulging with the power supply capacitors and my chat with Weaknees (as well as the previous posts here) make me believe it's a motherboard issue. I'll post back later if I see any changes in my Tivo's behavior.

    A gray screen (just uniform, featureless gray) can indicate a problem with communication between the drive and the motherboard.

    Make sure the combo cable is properly seated on the drive and check the motherboard end of the data part as well.

    It's also a well-known issue with the S3 & HD series, that plagued them until software 11.0g, which I have some inside knowledge about.

    TiVo denied it was a (known) problem, right up until the official TiVo staff leaked it to the call center people, that a fix was imminent.

    I had never once had it happen to me, until the "fix" rolled. Then, I got hit by it as often as those who had been complaining about it for years. It was a hardware issue, that they made a software band-aid for. For some reason, the new cases were limited to a small percentage of markets, clustered on/near the coasts. They opted to leave it as it was, since the numbers made happy, far exceeded the angry new ones experiencing it, post band-aid.

    While it is in the realm of possibility that a hard drive issue could cause a uniform gray screen, the more known issue was a gray screen, or black screen, depending if you had changed the letterboxing borders from the default gray, to black.

    If the gray you describe happens with the letterboxing borders set to black, that's a way to differentiate between any possible confusion, as to a cause.

    Last night I decided I'd screw the cover back on, so I checked the cables at the same time. They didn't appear to be loose, but I went ahead and unplugged and re-plugged. The gray screen did only happen that one time and rebooting appeared to fix it.

    And since I don't know how to copy 2 quotes, my software version is at 11.0m.

    As a side note, my HD was only unplugged about 5 minutes and when I plugged it back in, I got the flashing green light again. Again after keeping it plugged in for about 4 hours, it started up and and all was well again with recordings and watching live TV.

    I might have the same or related problem that I just posted here:

    http://www.tivocommunity.com/tivo-vb/showthread.php?t=519945

    On mine, the green light is on steady, but it blinks off once every minute or two when my display goes black. Is this the same blinking behavior described in this thread? I'm going to leave my Tivo on for a few hours and see what happens.

    Thanks....

    It's a continual flashing light. Once or twice a second. The Tivo does nothing else. Hope that helps.

    Yes, thank you. That's a different behavior from my problem.

    I know this is an old post, but I wanted to let people know that I had the FGLOD after a five-hour power outtage. I used a heat gun on the RAM chips and it worked perfectl...low setting on heat gun for ~30 secs. One thing I did notice is that after I got the green light to stop flashing, I unplugged it and carried it back from my workbench to the entertainment center and plugged it back in, The FGLOD came back on. I heated the chips again, plugged it in and left it so. Flashing green light gone an everything is working fine. Moral of the story is keep it powered after FGLOD stops flashing.

    If the FGLOD is simply a bad mem stick, do we know of a good source to order memory. Is it stock PC type memory or something special. I'd like to avoid pay $200 to weekness if possible.

    If you don't have any experience soldering and unsoldering Surface Mount Devices (if reading those words didn't cause you to shudder, then the answer is no), then you're better off hoping the heat gun or hair dryer will re-flow the bad solder joint.
