Default Hitachi 50VS69A Blue Light Blinks then shuts off, Need Info

I'm posting to see anyone has experienced this problem and there is a DIY fix. Any info would be appreciated.

I have a Hitachi 50VS69A that worked well until last Friday morning.

Here's the problem...

When pressing the power button, the power indicator light comes on solid blue and a fan starts up. After less than a minute, the blue power light starts blinking. Then it all shuts down.

I had a spare lamp, so I replaced it: No change.
I unplugged it for 10+ minutes to reset the system: No Change.

I called Hitachi tech support and was told to take it to a technician, who he would gladly give me the phone number to.

I called a tech and explained what it was doing. He said to do the 10 minute reset and listen for a buzzing sound, fans coming on and if the lamp was lit when i turn it on.

No and no Change.

I called him back with a report and he said it could be either the ballast ($150, the cheapist), the digital main board or some other board that is also very expensive.

Background: It is plugged into an APC UPS (350w) and the cable box is on a surge suppressor. Normally, I turn on the cable box, then the TV. This time there no single from the cable box. The screen showed that the light was on in the TV, but without a signal. I had to unplug the cable box to reset it and that seemed to be troublesome as well, but it finally started outputting a signal (it's connected to a 1`5 year old console TV now).

I've found a service manual for this model Hitachi, the 55VS69A & 62VS69A. It isn't much to read. It assumes it's being read by an experienced technician and some things are miss-labeled in the figures (number 6 is the optical engine, but 6 on the figure points to a pair of screws).

I see where there are some diagnostic LEDs on the main board, but I can't find how to observe them without taking the whole thing apart. So it isn't much help.

Oh, and I call Hitachi to complain because the dern thing is 14 months old, barely out of warranty. I was escalated to a "supervisor", who said I had to get it diagnosed before they would talk anything about helping. When she was told that it would $100 to get a tech out to the house, she said, "it's not my TV". Real sweet. I can see that their help isn't going to be much.

Any comments would be appreciated.

I have that exact same t.v. and have not experianced any problems. I am assuming that this is when you turn the set on, if so have you tried turning it on manually on the set itself. It seems as if it is being told to turn on then being told to turn off. Like with mine when you turn it on the blue light comes on solid, then when I turn it off the light blinks while the fan cools, then turns off when the light is cool. I wouldnt think that it is the light because there is a different indicator for that, in wich case according to my manual it doesnt turn off by it self, you have to. I know I havent given much help to the problem I was just trying to help you trouble shoot, like I said it seems as if it is being told to turn on then turn off according to what the blue power light is doing. Good luck and let me know if you get it figured out maybe pm me so if I have the same problem it might be of some help in the future, and I will try to find some more info to helpbyou out.

Thanks for the info.

But the weirdest thing happened last night.

Just before I loaded it on a cart to take it to the repair shop, I hit the power button one more time.... And viola! It started up normally.

The only thing I can figure is it must have been some weird signal from the cable box as the only difference between the failure to start up and starting normally was the cable connection was removed this time. I should have guessed that the cable box was the culprit since it was acting goofy when I turned the TV on Friday morning.

Is that possible? I mean I work with Dell computers all day every day and sometimes when they won't boot up, I unplug all power sources, leave it sit for 30 seconds, hook it back up and it boots up normally... sometimes.

FYI: I have a pdf of the service manual if you know of an ftp server that can be used, I'll post for anyone that needs one.

I am interested in the pdf manual you referenced. Please let me know what info you need in order for me to get a copy. Thank you in advance.

Default Hitachi 50VS69A Turns off by itself but blue light is still blinking

I had this same problem and was about to take it in to have it worked on then noticed quite a build up of dust on the back air vents so I vacuumed them off with my dyson sweeper and it has worked fine ever since. I think the build up of dust caused the heat to build up until the television turned itself off. Hope this helps they told me it would be between $75 to $400 to fix.
