Question about Sharp Aquos PZ-50HV2U 50 in. Plasma Television
I have a PZ-50HV2E and it turns off on its own. Sometimes it runs for the whole weekend with no problem. Other times it will turn off after exactly 15 minutes. If I try to immediately turn it back on it will not come on. If I turn off everything, unplug from power socket and wait 30 minutes. I can turn it on and it will then turn off in exactly 8 minutes. Same procedure, then the time is reduced to around 3 minutes. The strage thing is I get an E1 (Check Correct Cabling) on the screen before it shuts down. But I have checked cables a 1000 times but no change. Any advice? Not looking forward to boxing up a 50" to sedn to the repair shop.
The problem is most likely the the screws are loose on the inverter boards. The screws must be tighted as they provide the ground to the inverter bds. The inverter boards are undet the shields on both sides of the unit after pulling the back cover. One way to make sure that you are losing back lights and not video is when your picture goes black, shine a flash light on the screen at an angle and will see the video is still there. This mean the back lights are out. If you do not see the video it may be another problem

SOURCE: Sharp Aquos turns itself off
My LC37D6U had this problem, thought that I was going **** at first, came to find out that there was a firmware issue with the system. I got ahold of the updates for my particular system and just applied them. ** issues turning on and off now, just the sound going dead after 18 months.

Unplug it hold down the Channel Down button and the Volume Up button unplug it for 10 seconds then plug it back in and continue holding them down for another 10 seconds then release. I had the same issue and this fixed it now I have another though *~*

Unfortunately not really, it is the video board of the LCD that has failed, it is a major repair to say the least. You can check with a local repair shop to estimate the repair, but it will be spendy :(. I'm so sorry about the bad news there, but that's definitely what it is. If you happened to purchase the TV with a major credit card (not a debit card) there is a good chance it may still be under the free extended warranty most credit cards place on electronics. Please contact your credit card company to inquire if they do this, and they will be able to file the claim and get you a refund for the TV.
