Welcome to the site, Sandra. I'm Dan.

The model number you posted isn't coming up . Can you take another look? Also, how many times does that red light blink in between each long pause? There should be a pattern to it...

Expert:  Dan T. replied 2 years ago.
Count the blinks. It should blink a certain number of times, then pause briefly, then blink again the same number of times...

Ok. It Its blinked 34 times withbnpauses of 3 sec between each blink.and it keep blinking all the time like that. Maybe there is any way to restart it?

Expert:  Dan T. replied 2 years ago.
Sure, we can try restarting it. Disconnect everything from the back of the TV... power cord, computer cable, etc. Let the TV sit minutes... then re-connect only the power cord.

Press the power button one time.

Does anything change?
Customer: replied 2 years ago.

No. Its stiil the same situation

Expert:  Dan T. replied 2 years ago.
And the only cord you have going into the back of the TV is the power cord, right?

Dan
Customer: replied 2 years ago.

Yes.only power cord

Expert:  Dan T. replied 2 years ago.
OK, in that case we're looking at an internal issue. We would need to go inside the TV to make repairs. Is that something you want to do? Or do you need a diagnosis and cost on repair?

Dan
Customer: replied 2 years ago.

What about diagnosis? And are u repairing them here in UK? And what about the price and also in my opinion is the soft problem.well i bought this tv for £400 so if the repait costs 200 or more its doent worth it...

Expert:  Dan T. replied 2 years ago.

Yes, there are repair shops in the UK that are authorized to work on this model. You can expect £25 to have the TV examined, and that would be put toward the final repair bill, should you decide to let them repair it.

I do not think this is a soft problem. In fact, we mostly eliminated that possibility by disconnecting everything but the power cord and seeing that the problem continued. Rather, I suspect we are dealing with a defective or damaged main board inside the TV.

That being said, I'm not sure having the TV repaired will be cost effective. Even with the modest evaluation fee, you would probably end up seeing a £150 repair bill full issue, and you can purchase a brand new TV of this size £250 nowadays.

It may simply be a better financial decision to replace the TV in its entirety, as opposed to having it repaired. I do suggest, though, that you have the TV evaluated by a local engineer that can give you a full work up of the problem.

I hope that answers your question! If not, just let me know. Also, please take a second to rate the service I provided today, as that is the only way I receive credit questions here. I hope I was excellent, even if the news was not! Thanks!

No need to get snotty. If you're unhappy, there are far more appropriate ways to say it than to insult.

Best of luck with the TV, Sandra. Don't hesitate to let us know if you need anything else.
