SOMETHING IS LOADING DOWN THE POWER SUPPLY...COULD BE THE Y-SUS BOARD OR UPPER OR LOWER Y-DRIVE BUFFERS...TAKE THE BACK OFF SET..GIVE IT THE SMELL TEST AND EYEBALL THE FLAT I.C.`S ON THE THIN BOARDS TO THE LEFT OF Y-SUS BD. IF NO BURNING SMELL AND NO CRACKS ON THE FLAT I.C.`S ...TRY REPLACING THE Y-SUS BOARD...NUMBER ONE PRIME SUSPECT...DO NOT POWER UP SET WITH BACK OFF UNLESS YOU ARE QUALIFIED SERVICE TECH...JOE ACE

Here's a shortcut to what the blinking codes mean.
Strange how some people have 5 blinks. Most with this problem have 8 blinks (like myself)
I still have the blue-flash-then-shutting-off problem.. (8 blinks meaning voltage error) but I did fix the blue lines.. The lines across the screen can be very easily fixed whether they're blue green or red. . No, I mean REALLY easy. Took me longer to get the cover off. Once the front cover is off it takes 10 seconds. This link was also posted recently in one of the posts below as a solution..
(My lines didn't look like the ones in the picture mine were several evenly spaced blue arcs)
After some research I believe the flash/shutting off problem means the CRT is going. I've also read that it might be the D-board and I'm not even sure that that is... But If it is indeed the CRT then I'll let you know it's very difficult to find a replacement blue CRT as this part has been discontinued.. but I did eventually find an alternate to an alternate part (yes that's the 3rd alternate !)) online for $256.

If you're bold enough to attempt that then good luck and please let us know if it worked.
Or another alternative is there's a whole lot of Boxing Day sales goin' on right now.

The TV is on protect mode.
Try first leaving the TV power cord unplugged for some times, let say one hour or so.
Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.
If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.
The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.
1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.
2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.
If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.
If you are in situation 2 , then there is an internal fault.
Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.
Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.
If under warranty contact the manufacturer ringing the number on the user manual
If you want to repair at your own expenses, just locate any good qualified repairer.

I have the same problem, and it will get worse. I have read and seen video on youtube, stating that it is capacitors on the power board, that need to be replaced. I watched the tutorial video it seems pretty easy, I am going to try it this weekend. Will update.
