Samsung HPS 5073

I am amzaed you have had it for 3 years, this usually occurs about 18 months from purchase. Samsung, however are good to deal with than most.
Stop turning it on in the hope it will self reapair. It is more likely to self combust! The capacitors on the sustain boards have died, expanded and possibly split.
This is generally as a result oif poor components ( made in korea or china) being used to keep the price down. However the life expectancy is compromised.

This is not a DIY repair ( many have tried this option only to find it does not work out . Mainly becausde all 3 boards are recommended for chaning and they need to be set up correctly with the right feeder voltage to each of them.

an estimated repair cost for your set is in the $500 dollar range

Please rate my help++++Thanks for using FIXYA

it seem like the sales person was working for the competitor at that time too.

If your screen is taking that long to turn it is a hardware issue with the screen and I would suggest contacting the manufacturer and try having them repair it at 18 months it still may be under warranty.

I hope this helped.

Thank you,

Need to get service for main board replacing.

Try unplugging the washer for about 20 minutes then plug back in and use. I have found that this actually works! The only thing I can figure out is that it takes time for the electronic control to clear. If that doesn't fix the problem I would call sears tech since it is less than a year old. They have a 1-2 year warranty.

If you have a complete shut down, How do you turn the set back on? Do you have to wait? Do you have to unplug the Set? In most case you may have a bad Power supply board. Part Number
BN96-01805A. Average Cost $60

First, hide the remote from the set. A button stuck on the remote can cause all sorts of eerie behavior. Barring that, it's time for a shop visit...accordianman
