You can download a PDF from here: http://www.servicemanuals.net/results.aspx?type=SM&brand=0&model=50EX20B Make sure that the coolant is not leaking out onto the printed circuit boards. i have had the remote sensor cause this problem before and also I have had bad capacitors in the sweep and the main power supplies. Good Luck

Refer to owners manual ! Blinking indicates the type of fault that is occuring on all your tv sets. example : power light on red - indicator light beside it green but blinks rapidly for half a second rapidly then shuts off. This refers to a faulty lamp or a lamp that is near its expiration. Read your manuals if indicators refer to easy repair sweet, but if it says call tech then bummer...

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,

Since the set seems to recover somewhat, Id look for poor sonnections first rather than defective components. If you can solder and arecomfortable working inside the set, you may be able to fix this yourself. Are there any other symptoms other than just shutting down? For example, blinking standby lights?
