Question about Hitachi 46UX24B/25K 46" Rear Projection Television

1 Answer

Power goes off intermittently while viewing

When power suddenly goes off,I use remote to power on producing this result: I hear the familiar "shutting OFF" sound ,I press power button on the remote a second time and the power comes on as usual. I am OK for sometimes an hour,sometimes only 5 minutes. The overall picture is always great. This set is 10 years old. I am 70 and can't afford another new TV at today's prices. Would it do any good to unplug it,take the back off and vacuum out the dust? This is NOT a worn power cord problem ; it has not been moved for 10 years.

    When cold, the TV comes on normally. After it warms up it shuts itself off. It first did this about 1 week ago, and wouldn't come back on at all. I unplugged her and she came back on and after about 3 minutes the screend blinked once or twice, but stayed on. This weekend she started shutting of again with a vengence. Every 2 or 3 minutes and unplugging doesn't make a difference. On and then off. I read the other post suggesting a voltage regulator, but I am reluctant to start buying and hanging parts without some other confirmation. Is that a common fault / repair? Are the others AS common or is the VR in a 12 year old set a likely candidate.

    Intermittently turns itself off. Can be turned back on after a few seconds, but may shut off again at any time.

CHECK FOR CLEARED COOLING VENTS & FOR PROPERLY WORKING COOLING FANS. THIS WILL CAUSE SHUTDOWN OF THE UNIT. IF ITS ALL CLEAR, YOU PROBABLY HAVE A POWER SUPPLY ISSUE.

The television is shutting itself off to protect itself. The blinking light is a code pattern. The specific code determines whether or not you need an LCD Controller Unit, Main Board, power supply or something else. You would need the service manual. There are parts distributors you can get it from and the parts as well. If soldering and tv repair is not something you are entirely familiar you may want to seek a tv repair person. The manufacturer's support may walk you through the service menus to complete a factory reset depending upon the symptoms.

1997 Grand Cherokee 4.0, ignition shuts down sometimes backfires and keeps going, or dies completely and hopefully starts up.already replaced coil and crank sensor.


The likely answer to your problem is that you have an intermittent disconnect in the ignition system. If power supply to the ignition system drops out, some fuel still goes through and when power returns it ignites in the exhaust resulting in a backfire. I would look for a bad ignition switch, or other loose connection that could me making/breaking contact intermittently.

Gateway fpd 1960 goes black intermittently


Your inverter is dying. It produces ~2k volts for the ccfl (cold cathode fluorescent lights) that surround your display. At a few milliamps. Probably bad or leaking capacitors on the inverter or power supply board. So it is either using too much power (bad ccfl) or a weakening power supply (higher likely).
It could be cold solder connections becoming intermittent. Remove the base, remove the screws on the backside, and split the case CAREFULLY. Inspect the power supply and inverter for obvious failure or leaking capacitors. Replace same... If your lucky, it will work.

'standby' mode and akb error number


AKB 66 in self diagnostic test means...TV goes to standby (shut-off) for AKB problem 66 times. AKB is White-Balance signal and it is not proper or maintained in your TV. So error signal produced and TV goes to shut-down state.
Regardnig Standby button, its available on remote only. If you push TV Power switch, TV will switch ON, push it again to OFF TV. Power Button on remote set TV in standby status and you dont need to push power button of TV itself.

TV won' turn on


Solder, solder, solder! Shut down circuits protect crts to avoid permanent damage. If any of the deflection circuits are defective, or intermittent, shut down occurs. I have not only seen bad solder on deflection circuits, especially vertical, but also intermittent connections on the yokes themselves. I've also seen shorted convergence ics cause shut down. Don't forget solder connections in the power supply.

No Power


The first thing to check is the horizontal output transistor,it might have shorted out and opened the fuse or safety resistor that gives him power to operate,sometimes it goes bad by itself and sometimes the output transformer goes bad and takes him out too.If you are familiar with tv service you have a place to check but if you are not to familiar be safe and seek the help of a servicer.Let Us know how it goes or if you need more information.
