Black screen we just replaced the bulb on our tv. shortly after we turned it on and we had a black screen again. this time there was no sound. The tv turns on and the power light flickers

Replace the medieval TV.

OK. I have this same issue. I replaced my bulb a month or so ago. TV worked fine. Then one morning I turned it on and it was on for a good while, till it went to a black screen w/ sound only. Lights were going through the reboot process as designed for 8 attempts before it went to the solid red light. From the red light, if I unplug and plug back in, the tv will come on for a given amount of time, which varies, and then cut to the black screen. A repairman told me that it sounds like the digital board is bad. He wanted $150 for the board and $100 labor. I cannot find anywhere where the board would be located or where I can purchase a replacement.

TV has gone into "protect mode" to do just that to protect against the damaging failure that has been detected, you will need a servicer to diagnose the failure. Good luck and Merry Christmas!

Seems like the bulb needs replacing.....

power pack capacitors are going bad, need to have then replaced.
hope this helps

Start by replacing the bulb. If thats a no go, check the ballast. Its a small circuit board directly underneath the bulb housing and is replaceable through the bulb panel. If those two don't work, comment back and I'll walk you through more 'in depth' repairs.

You, more than likely, need a new lamp

alright guys...blew a bulb....fixed that. still didint work...found out it was ballast...replaced that. tv worked for a month..all the sudden hdmi input didint work id plug in my playstation and screen would turn green and say "hdmi color has been corrupted" im thinking wtf? so a week later it works fine then just turns off in middle of watching espn... comes back on an hour later...only to turn off again...it just turns black for ten seconds then just turns off and the red and green lights blink at intervals of one second....replaced a bulb..not that, same problems.......when the tv comes on for the ten minutes before it quits working the pic and sound are great i just dnt get it...is it shorting out? color wheel bad? a fan?

Your lamp has most likely blown out. that is what happened to mine and once I replaced the bulb it worked just fine. this is one of the cheaper stores to find a replacement bulb, www.bluestar-online.com
