This is a classic symptom of a poor solder connection probably in the high voltage section. If you can solder, you can fix this yourself. Look for solder connections that appear grainy or have rings and resolder them. That should resolve the problem. If not, then we need to look for parts that are being effected by heat.

Keep us posted.

Okay 2 blinks isnt a error code, so your set isnt shutting down due to a protection issue, so I would suspect one of the low voltage regulator transistors or the horizontal output transistor as being defective

That depends on which part you will end up needing, without troubleshooting the set there is no way to tell which part or parts are defective.

Thats hard to say, most tv repair shops will want over a 100.00 just to come look at it. Then most of them wont do component level repairs they will insist that it needs a new Circuit board at around 400 to 600.00 would be the guess on a repair shops estimate.

No they will require soldering and unsoldering. I suggest that you go to the following link and order the service manual for your model, as they will email it and then help you for free with online instant messageing to diagnose it and then they have any part that you would require as well. Heres the link.

your owners manual has the procedure for overriding the parental lock so you can re-set it again. It is a little complicated and requires the pushing of a couple of keys at the same time. Look at your manual. If you don't have it, download it from the net.

best place to get them with instalation instructions included is the following link. you need two STK392-570 ICs

i will stand by techman's assesment of your problem. how dare you give him a poor rating. what the hell you little pukes come to us for advise and when you get an answer you don't like we become the bad guy's . we have been servicing electronics collectivly over 50 yrs. that being said you should be singing praises to technicians that take time to help you on there spare time. we may not always get it right but we try.

Could be a problem with the convergence IC's or a resistor(s) / capacitor(s) around the IC's.
I suggest calling a service guy and getting the TV fixed.
