Question about Hitachi 53SWX12B 53" Rear Projection Television

1 Answer

Picture is out!

There is power coming onto the set. I have unplugged the entire TV set for a few hours to see if there is any effect - nothing. The menu screen, volume indicator, or channel number will not even display, so I know it is not a cable issue - I just have a black screen. Am I hosed?

    I picked this up from someone on craigslist. Neither the sound or the picture work. Power light comes on but screen is black. Could this be a bulb? Or am i looking at something else totally different? Thanks

Set will often have problems starting back up


you have a high voltage arching problem. the crt has about 33000. (thirty three thousand) volts on it. the anode lead is arching to the chassis(ground) around the crt(picture tube). the anode lead is the big red wire on the very top of back of crt. with the back off, you will see the big red wire and it will have a suction cup about 4 inches round connecting to picture tube. unplug. silicone around suction cup. let dry for 24 hours. enjoy. you might get a little shocked even when unplugged, but wont hurt you.

TV randomly shuts off and does not come back on unless you unplug it and replug it back in


This is likely caused by voltage leakage which happens due to a build up of dust and other contaminants that make its way into the inside of the set.
1. Unplug the set for 4 hours or overnight and leave unplugged.
2. Remove the back cover and vacuum off any excessive dust and dirt.
3. Using a damp cloth, clean around the neck of the picture tube where the large wire connects (this is the main power wire). Wait about 10 minutes and then re-wipe.
You may find that you need to repeat the process a number of times before the problem will be fixed entirely.

Picture goes off


A temporary solution is to unplug the TV for a few minutes, remove static from the glass with your hand. It is important to unplug rather than turn off. If you have a degauss button you can also press that before unplugging. Wait several minutes or an hour. Then plug it back in. If you have Picture in Picture it may be an issue with that and to permanently solve may need a repair person. The unplugging may get you by for a few days at a time. That's at least better than an hour.

Picture getting darker


The tv has a room light sensor,
shine a bright light at it , does picture get brighter?
other wise when it is cool open the bulb door , is it coated or blackened, Don't touch bulb at all.

and a heavy covering of dust on internal mirrors will cause the same effect.
you will need help to clean it.

Toshiba 43A61 - No Picture, no sound


If your set all of a sudden won't come on, e.g., the screen is blank, but the LED on the under the screen next to the on/off switch keeps flashing, then there may be an internal fault on the set that needs to be reset.
To force the reset, try this:
  • Unplug the set and wait a few seconds
  • Replug and see if the video returns
Whenever the set senses an internal fault through its monitoring circuitry, it essentially shuts down the set. The flashing LED provides the indication that a fault has been detected. Removing power to the set resets the monitoring circuitry. When plugged back in, the circuitry again does a check of the system. If it finds that there truly is a problem, then the set is shut down and the LED will again flash. In this case, you need to call a service tech. Most of the time, however, the unplug/replug routine is enough to get the set up and running.

Power light flashing/ no picture


I have the same problem. The only way to get the TV to come on is to unplug it, but once you get it back on it turns itself off again in a few minutes.

No picture or sound


If you had a burning smell, well the board is toast. These sets are made to replace the entire board at one time. Before installing the replacement module, the picture tube should be checked. A defective picture tube ( such as a G1 short) may cause a failure in the power supply section.
