    I have the same Hitachi 50UX52B. Won't power up. I can plug it in, hit the power button and the red light comes on. All 8 green and the red lights come on. But no picture or sound. If I turn the power off, all of the lights go out and then I would have to unplug T.V. and re-plug in order to get the power button to work again. Since all of the lights described in a different solution light up, what could this problem be?



1 Answer

The symptom you have needs to be looked at by a qualified technician for proper diagnosis. There are 9 LED`s ( 8 green, 1 red) in the power supply that light up under normal condition. These LED`s are used to help pinpoint the area of trouble. For example, when power is applied all LED`s but one lights up. The unlit LED may indicate the +27 volt source is bad. That will alert the technician to check components related to the +27v line. Since there are 8 green LED`s and 1 red, each having multiple suspects leads us to Mr Spock`s comment to captian Kirk." there are endless possibilities"

The problem is in the power supply, the most common cause is an open fuse and open capacitors, if the set is more than 10 years old consideration should given in replacing the tv especially if a professional gets involved.

My Sony 52" LCD kdlw3000 tv, which is almost 2 years old, went to standby mode after our power had been off for two days due to a storm. TV worked fine before we lost power and it's plugged into a surge...

Just as our modern sets can remember user settings when the AC goes off, they well may record error conditions for an extended length of time too just as our cars do. Flash memory (used in such applications and only type used in digital cameras for example) can keep information for a very long time. Even if not used in your set, there is surely backup provisions that can keep info handy for days and possibly weeks by using components that mimic batteries to retain even standard memory for weeks.
Most PCs have provisions for discharging this kind of circuit which then resets possible stored error conditions and returns stored values to factory conditions.
Feel lucky this time I'd say.

Sony KDF-50E2000 shuts down and blinks repeatedly twice.

The 2 blink error is a temperature error and the 6 blink error is a thermal fuse error. You may need to unplug the set and get you a can of canned air, take off the back lower cover and blow out all of the fans inside the set.

Turned off while watching, won't turn back on.

The TV is in "protect " mode,which means that it is shut down because of an internal fault condition. - unfortunately you need a technician to investigate the problem . THis is not a job for a hanyman. Sorry ..
