The general problem with LCD type TV's is that the power supply
fails. They are very sophisticated designs that are difficult to
troubleshoot and generally best to just replace the module, but
sometimes there is visible damage in some of the electrolytic
capacitors (visibly bulged) and high voltage rated parts can be

If you have Hitachi model number 50UX58B, 60UX58B, 50UX58K, 60UX58K, 50SBX78B or 60SBX78B and you have the following symptoms you may want to grab a repair kit from www.TvRepairKits.com. They have put together a kit that includes the parts and instructions to fix these models. This is a fairly common problem with the above model numbers. It is typically caused by a blown capacitor and pico fuse. Again, you can get a kit from the above address.
Here are the symptoms...
Primary Symptom: No Audio or Video. Power light will come on briefly then shut off.
Other Possible Symptoms : The green LEDs on the circuit board light up for a few seconds then turn off.
Hope this helps,

If the power supply outputs are good! Then I would say the back light inverter is bad! If the screen stays black and does not come on.

Hi, this is main board failure and you will need to replace this vital board. you power board is fine but, it is unable to send a proper current through the main mother board due to the damage at hand.

IF your not getting sound and its shutting down it could be a the main board, or the power supply (huge board in there.) I just got done parting one of these tvs that was in a vacation rental. the tv met with an unfortunate accident so the screen was cracked and so on. Anyhow if your intrested i have the main board and the power supply board for that exact model. I was listing them on ebay and saw this post. Listing here. I am going to probaly get about 25 buck a board (very cheap) plus shipping. IF your intrested let me know and I list that power supply board as well. I can't guarentee it will fix it but its worth the shot for 50 plus shipping. form my experience with mostly LCD tvs if your not getting sound odds are its the main board. I also listed what was refered to as the signal scaler (logic board)
