Question about Hitachi 43UWX10B 43" Rear Projection Television

Flashing Power Light

I've noticed that others have described symtoms similar to this, but I haven't really noticed that anyone knew what the problem was. Maybe I just didn't search thoroughly enough. In any case...yesterday when I tried to turn the set on the red power light flashed on and off at about 1 second intervals. After a couple of minutes it flashed off and stayed off. Screen stays blank. Happens if I power up with the reomte, or the power button on the front of the set. Problem is repeatable. Any ideas? Thanks!

    Thanks, Leadtech. At least now I have a sense as to what is happening. Time to call in a tech.

    Cheers!

This set is going into shutdown. It has a safety feature that will not allow the set to turn on until it checks certain circuits. Inside the set there are multiple Red LEDs and one green one, that light up at turn on. One of them is not turning on and thats the circuit that needs repaired. The most common I've found is the Horizontal Output circuit. Usually the fusible link on the secondary in the power supply. Sometimes it goes as far as the High Voltage Transformer. Of course this is just one of the possible four circuits that cause this symptom. Hope this helps.

When turning on, the screen remains black but there is a clicking noise like its trying to turn on and a light intermittently flashing on the screen


The power board of your TV is known to go bad as you will soon find out if you try to find a replacement.

While the described symptom may or may not be caused by the power board the above fact is a serious reason to look there first.

In all fairness we haven't worked on this particular power board, but we've worked on many others and you can send it over for evaluation if you wish.

I've got a dim blue flashing light from my subwoofer with Soundsticks usb. Is this a poweradapter problem or an electronic problem?


Hello
It is with its power transformer problem itself. There is a protection fuse inside, which will blow out, of any direct short circuit occurs inside the unit. when the fuse blows out, a blue light, such you describes here can be seen from it, as its body is transparent.
But, before replacing this fuse, you have to find out the exact reason for its blow out, before replacing it with an other similar one. OK.

as per your report we understand that there must be something wrong with boiler/hear or with the heating sensor. So that when you try for hot water because of safety reason it gets automatically switched off. Please rush near to your service center as we do not advise you to fix this issue.

I had a very similar problem (did not have the abs light) but had the other lights. Changed fuel filter as the problem seemed to be a fuel pressure problem. Turbo was back and no flashing heater light, engine light will go out after about three cold to hot starts as long as no other problem exists. It's worth a try as it is a cheap and relatively easy repaire to do. If not the answer take to a garage who can interrogate the computer.

Inlet blockage red light flashing


Try turning the machine on its side, undo the bottom and check that the polystyrene float (attached to a switch) is not somehow jammed. This float cuts off the water if the machine leaks internally, and produces the symptoms you describe. It's a really good machine so don't throw it away!!

If that still doesn't help then it might also be the motor brushes, which produce similar symptoms - if your machine starts to fill but then flashes and just drains again, it's almost certainly the brushes. This might be the case after you check the float problem.

I somewhat agree with other solutions on this page. I agree that what you are describing is a severe misfire, however there are MANY possible causes for a severe misfire other than just the spark plugs...I recommend diagnosing the CAUSE of the misfire before spending any money "GUESSING" and replacing a bunch of parts.

Also, a code P0300 is a "RANDOM MISFIRE" code which indicates that there is definately more than one cylinder misfiring. Your computer MAY display this code, however, a SINGLE cylinder misfire can also cause a loss of power and the check engine light to flash.
You may just have something like a bad coil on one cylinder that needs to be replaced. This is why PROPER diagnosis is recommended.
