Question about Dell W1900 19 in. HD-Ready LCD Television

Open Question

TV Cuts off on its own

I have a 19? Dell Flat Screen TV that is about a year and a half old. A couple nights ago it just randomly cut off on its own. Last night it did it a few more times. And I even noticed in the middle of the night that it would make weird noises (while it was off) like it was trying to connect or cut on and it couldn't connect. The noise sort of sounded like it was coming from the speakers and it was a loud noise. The only thing I have the TV hooked up to is the cable and the actual outlet. I made sure all of the plugs were plugged in tight, and even tried plugging the TV into a different power outlet last night and that did not resolve the problem. After being woken up in the middle of the night by the loud noises the TV was making (while it was off) I just decided to unplug the TV all together and I have not plugged it back up since. Do you have any idea what could be causing my TV to automatically shut down on its own? And do you have an y suggestions as to what I may be able to do to fix the problem? Thank you, Lindsay

    Same problem. The tv cuts off for no reason. It has gotten so bad the tv is virtually unuseable. Has anyone figured out what causes this or how to fix it?

If you are a tech. Check the voltages going to the Logic Board, if one is missing (12 or 5v. Then that is most likely due a an IC failure on the power supply board. IC 901 Don't quote me on this, but I know it is less than $10. Sorry, I only have 1 left, the last one I did was in Aug2006 so memory is fuzzy. Kegtapper

the problem is the audio amp board has been fried. It needs to be replaced. This will restore the actual sound transfer to and from the speakers.

Hitachi 42HXT12U, It turns itself on and off at random. The tv is under a year old.

Fault with its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Screen just split in half

Is the tv still in warranty? The problem is the upper buffer board, it's a small board that controls the upper portion of the screen. You will have to consult a service center to get it, it's very easy to install
