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

Without the correct meters and equipment it can get exspensive replacing boards however it almost has to be located on the power filter or the power board. I would suggest the power board over the power filter.

Good Day, Gil;
Your problem is in deflection circuit (115+v) check these: FP05, DP15, Q777, QH01, TH01, T701, etc. BUT suspect C707 1k pfd, 2kv, and check all the pico fuses (brown) 2" to the right of cap. Good Luck, big IRISH.

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,

I had the same problem with my 46" Hitachi TV. We left it unpluged for a couple of days (literature says at least 4 hours) Pluged it back in, held in on the AVX and power button at the same time, this puts it into self diagnostic mode. Error codes should appear on the TV screen, then it should instruct you to hit any key to continue. Press the AVX button and it should put your TV back to normal. I suggest however, that you download the specific manual off the internet for your TV. I got my manual from an electronic forum site (http://www.eserviceinfo.com). My TV model is Hitachi 46EX3B. Hope this helps.
