Re: screen flashes

I can't say that I have seen this on a Hitachi, because I haven't, but I have seen it on older Zeniths. The problem with the Zeniths was in the power supply. An electrolytic capacitor changes value and slows down the switching of the power transistor. This means sometimes it works, sometimes it doesn't. Replacing the cap solves the problem everytime. I would look in this area. Good luck.

Sony Trinitron KD-28DL10U switched off suddenly to standby mid programme and won't come back on.When trying the remote on I can hear it click on and immedietly off again.Switched off at set and socket and...


In time as the Sony Trinitron ages it begins to have power issues. While this can be true of most tube televisions it's the rate and severity at which this happens to Trinitrons that makes it particularly of note. Many Trinitron owners have complained of the Trinitron set turning itself off randomly and frequently. Some sets have failed to stay on for longer than a few minutes at a time. Eventually some sets will not turn on at all. These problems grow more severe with age.

Check the power cable running from the Sony Trinitron 32. Make sure the cable is completely inserted into the power connection on the rear of the TV as well as the local power outlet.

Disconnect the power cable from the electrical outlet, then plug it into a different connection. It is possible to electrical outlet has died, forcing you to obtain a power current from a different source.

Check the cable connection running from the cable/satellite receiver or VCR. If the TV is on but no picture is on the screen, the problem is most likely due to a connection issue.

Power off the cable/satellite receiver, then press the "Video" button on the remote control to switch the Trinitron 32 to the video input signal. Turn on the cable/satellite receiver and the programming now loads onto the television screen.

My Sony KDF-50WE655 does not turn on. Only the standby LED Flashes several times and then goes steady green, but the lamp light remains off.

You just count the number of blinks of the standby light before it goes out to green. In sony sets this blinking count ic critical for us to locate the faulty stage. You just count it after switch it Off by Power switch and Switch it On by the power switch at the front of the TV, for at least three or four times, and make sure abut the number of blinks, and report it to me. Ok

Samsung 50" DLP TV turns itself off

I had the same problem which also included the picture having streaks of red in it sometimes too. I found that both problems were due to the TV getting too hot inside. I bought a $7 small 4" fan from Walmart and pointed it at the back "door" of the TV (where the bulb can be replaced). Both problems have disappeared which I think is due to not letting the interior get too hot.

Not sure if there is an internal fan to cool the parts inside, but if there is it is not working well enough.
