The TV is in some kind of protection mode, the blinking LED show you an error code.
Try pressing 062596 and then press menu button (do these in quick motion, don't let them to time out while keying)...see what happens
Well I think that if you would have a service manual for this set that would help a lot, I can send it to anyone who wants it via email/gmail. Let me know if anyone want one.

I also heard that this problem appeared with some people because the of the burnt fuse in the TV. To fix that it has to be taken to the tech shop.

And yes I also heard about this issue many times, seems like this TV set is very popular with this kind of problem.

Hello tvpassword,
It sounds like a power supply problem, or at least a startup issue. This might be caused by any number of problems, but I would suspect that it, the problem that is, is in the Horizontal section of your set. If this is the case I would suggest that you get this TV repaired at a qualified TV repair shop, due to the section of the TV that is involved, dangerously high voltages are present and could cause bodily harm if a mistake is made.
If you are going to attempt to do this yourself I would advise that you know electronics before attempting this, if you do not, my first statement stands.
I hope this helps,

This is a bad power supply and an easy fix. Their are several electrolytic capacitors on the power supply. If one is bad it will have a bulge on the top. Mine had a bad 2200uF and a bad 1200uF capacitor. About $7 worth of parts at Radio Shack. Radio Shack had the 2200uF but it was axial leads instead of radial. (leads come out of each end instead of one end) but It will still fit. They only had a 1000uf capacitor so I combined that with a 220uF capacitor and wired them in parallel. Make sure you put them in with the correct polarity.

Commonly it's going to be a power supply related problem. The two boards that need to be looked at is the Main Power Supply Board or the power supply board for the screen. The one that powers the screen, some manufactures call it a Backlight Inverter Board.
If you have some electronic experience, you can sometimes find a Service Manual for the TV over the internet for less than $20. It will have the all resource material for repairing your TV model. It's just the matter of replacing the bad part on the circuit board.
