This is a common senario for the HITACHI 50UX26B
Shuts Down Randomly. May Take 2 Hours Or 2 Minutes.

After Pulling The Chassis & Resolder All Heatsinked Parts & Connectors (None Looked Suspicious To Begin With) Problem Still Existed.

Replacing The Strm6511 (Ici1901) Fixed The Set. Changed The 2 Small Electrolytics Next To It For Good Measure.

So from a professional that has fixed this specific model multiple times, this is what is suggested, replace the strm6511 and the 2 electorlystics and you should be good to go. Let me know if you need any further help

On my Hitachi 50UX26B the only button that is working is the power. Neither the remote or the buttons on the TV will change channels or volume. Today it also has a wide black strip in the middle, about 24...

you likely had a power outage, unplug set for at least ten minutes and put power back to it.

Seen this in a lot of these sets and owned two of them myself.

before you rate this solution if you have a question let me know.

Unplugging set and plugging back allows the microprocessor in the set to reset

Hitachi 50ux26B keeps turning off.

There is a chance that the one of the power relays are causing the problem. They have been known to be intermittent and even work for 5 sec. or 5 days before failing. When the back is off, turn the set on and when it shuts down lightly tap the relay/s in the power supply lightly and see if the set comes on for any length of time. If it does, replace the relay
and you will fix the problem. Let me know what you find.
Hope this helps,

The TV is a Phillips Matchline 55"; wide screen, approx 7 years old.When switched on the LED goes red then there is a clicking sound then the LED blinks red continuosly and there is no picture.

The TV is going into protective shutdown. What is the model number of your set? I may be able to help you depending on the chassis number.
