I have a SV2000 TV/DVD combo WV20D5 Manufactured in 2005. It has set for about a year unplugged. I got it out the other day to use for my game systems and it took me about 20 times of turning it on before it would stay on. I started playing Halo ODST online and after about an hour it shut off and when I would turn it back on it would shut off again after around 2-3 minutes or so. Most fixes is to simply turn the sleep timer off... For me, it's not so simple. I lost the original remote 3 years ago and had been using a universal one to change chanel, volume, etc.. But, it will not access the menu, so, I do not see how it could be anything accessed through the menu such as sleep options. Also, I have never had any other problems with this tv before.
