Olevia LT26HVE TV shuts down after being on for about a half an hour. After extensive searching on the internet for a solution, I've solved the problem by changing in the input cables. The original cables were component video cables from a digital cable box. I changed out the component video cables for an S-video cable and the problem went away. I hope this helps someone out there. Olevia is out of business and there is no support from them. Lots of advice on the net about the power supply and bad electrolytic capacitors - I checked all of that and found no problems. I stumbled on the above solution when I noticed that the problem stopped when the TV was disconnected from the signal input. When I re-connected the input signal, the problem reappeared.

My Olevia TV went out after approx. 16 months and it has been in the repair shop almost continually for about 6 months. The availability of parts seems to make these televisions virtually impossible to repair. Do not buy an Olevia TV and expect customer service/parts.
