Question about Televison & Video

Open Question

I have 50 inches plasma Hitachi TV (ALiS 1080HD). As the TV was on, the screen stopped showing (no picture) and no sound could be listened as well, without any reason. The power light started flashing (on and off) so I turned the TV off from the power supply (as the remote control was not responding). Few seconds later when I turned the power supply back on for a moment I heard a sound (making me believe that the problem was fixed) but once again the power light started flashing with the same end result (no picture & no sound).

This is almost certainly the device that sends electricity to the the plasma in the panel after failing. Bring to your local repair shop and expect to pay 300-400 parts and 100-200 labour.

Cheers,

SOURCE: panasonic viera tv won't turn on. Power light

hello, you have a either your su, sd or sc boards fualty and it is a driver sos1 thats what the manual reads the best thing to do if your not electronically inclined or able to fix it is to get a service manual and make sure it is for your specific model and size you will find what the 7 blink codes mean, on my side i have a 42 in pana the service manual for this set and your is similar so since it is not the same model i cant tell you exactly what the truoble is but your best bet is to find a service manual find the 7 blink fualt then without getting ripped off you will know what the service man needs to do if you dont know or cant replace the parts yourself that is besides having to download firmware from your computer to a sd card and update your set but you need to solve the blinking code first it may solve the entire issue. the tv should come on when you resolve the blink codes or replace the fualty board or boards

My 50Hda39 50 in plasma doesn't work through the coaxial cable hook up


Please contact the authrized service center for Hitachi. Sounds like corrupted firmware. Firmware update is necessary, and the firmware to Hitachi is very difficult to get by internet. If you wish to get some details, check the site linked here. Surf the site in "MOSAIC" view. It will make surf easy. Surf the site with patience.

When I swicht on the tv it swicht off by itself 5 seconds latter, what's happening


This would point to a fault in the TV that needs to be repaired by a Technician. It could be the capacitors in the power supply as a lot of units used caps that expand and leak and at this point they do not do any filtering but can actually short out the circuit. These can be observed in the power supply section. I have repaired many LCD type displays by replacing caps and they ran well over a year of testing.

Hitachi 50 inch plasma - no sound, no picture, red light on start up in the lamp and temp indicators on the front of the TV.


If it has lamp and temp sensors it is not a Plasma---locate and remove the lamp and look to see if it is shattered inside--owner manual will tell how to remove--its behind a door on right side or rear of set in most cases.

Tv keeps turning on and off


You probably have blown capacitors on the PSB-power supply board. Recaping with new UF caps works 90% of the time. The set turns itself of into a fault protection to keep from damaging more components internally. A few bucks a soldering iron some solder should do the trick.

Check your cables and TV input settings.  Can you get to the on screen menu?  Does anything appear on the screen when the tv is on?
