Question about Hitachi 43UWX10B 43" Rear Projection Television

1 Answer

Turns on randomly

Turns on in the middle of the night and the Satalite logo floats. Both satalite and TV are turned off at night and are not plugged into one or the other. It will also turn off after a while. I turn it off, say at 3:00am and it will be back on at 5:00am. I have checked and all internal timers are off and I have even turned off the clock in the TV. No difference.

    The Sat. receiver does not turn on. I did dis-able the auto-upgrade feature in the Sat. receiver (set for 3:00 a.m.) - no change, still have the problem. I don't think it's a power problem. I am a retired Elec. Engineer and I see no signs of power interuption or overload, at any time. Another interesting point, (why I dis-abled the auto up-grade) it only happens at night. This morning it was on at 5:00 a.m. I turned it off and it was on again at 6;30 a.m. Same pattern as in the past. Tells me it is definatly a time oriented problem. No timers are on in the TV or the Sat. receiver. I also killed the clock in the TV. I'm about out of ideas. I will leave the Sat. receiver ON tonight and see what happens. Hitachi is no help at all. Like talking to a post. They apparently don't give a shit.

    There are 4 CFL lights in that room. I have been leaving one on all night, so I turned it off. No difference. That was a good shot since CFL lights do not emit a total spectrum of light like an incandescent bulb. So there was a chance that it was emitting a light source close to the remote light (infra-red).

    Since the on/off problems happen at night (mostly), the cold/warm fluctuations could cause the problem. It has turned on in the daytime once in a while. Usually when it has been off for an extended period of time and/or we are gone. I guess I could just plug it into a separate power switch and turn it off at that point. That would "band-aid" the problem. I am stubborn enough to chase this problem to a better solution. Surely Hitachi has heard of this problem. I will see if I can bother them enough to get some answers.
    Thanks,

Ed,
since both the sat and tv turn on suggest to me that you have some sort of power problem in the outlet. I once had a customer complain of the same kind of thing, turned out to be the hotwater heater loading down the line. try a surge protector with battery backup the on used for computers, if that solves the problem then have an electrian come in and chase the problem.
you see, some of these sets will turn on after a power loss.

    I'll try to research this one for you, it may be a soft ware issue.

    one other question I have is, do you leave a CFL light on in the room or adjacent room? CFLs have been known to cause weird problems

  • Robert Johnson Jan 08, 2008

    I was just on a call with the same problem here in Maine on a samsung tv. the problem was from the front plastic power button being too close to the internal switch. the set would turn on due to flexing of the plastic front bezel. heat and cold fluxuations would cause it also. this is my best guess, there were no soft ware bullitons on this problem.

I have satalite and i can not get the tv remote on satalite so i can not change channels with my sat.remote


Check with your satellite provider's web site for the proper settings for your TV,
If it is a Vizio, there will be settings to provide most, if not all, of the functions to control your TV with the satellite remote.

I HAVE A TOSHIBA SATALITE A135-S4427 TURNED IT OFF ONE NIGHT WORKING FINE, THE NEXT DAY IT WONT TURN ON. I HAVE POWER THRU THE CORD AT ABOUT 18+ VOLTS BUT NO INDICATOR LIGHTS OR POWER TO COMPUTER. HELP?


Try removing the battery and power supply, hold the power button for about 10 seconds then just plug the power supply back in (not the battery) and see if it turns on.
Holding the power button with no power supply can discharge any stored power in capacitors.

MY TV TURNS OFF WHEN ITS ON FOR AWHILE OR I HAVE TO TURN THE SATALITE OFF WHILE THE TV IS ON FOR ABOUT 5 MINUTES THEN TURN THE SATALITE ON AND I CAN WATCH TV FOR ABOUT 3 HRS.


Hello the problem resides in the power supply, there are two capacitors that go bad in this model that needs replacing, look for caps that have buldged at their tops these will be the bad ones, the values of the caps will be 1000uf or 2200uf rated at 10volts working voltage, replace them with same value but increase voltage to 16 volts working voltage.

Direct satalite failure


If the tv works and its just the sattelite portion of the tv that doesn't work you can alway just use a new sattelite box and connect it to the tv via the rear inputs on the tv and then just select the coresponding input to view the sattelite chanels.
