You never have said what kind of surge supressors that you use. Walmart 7.98 surge supressors are not very good. You need one by APC or Panmax or Isobar or any major surge suppressor maker. I have battery backup surge suppressors on my TV, av receiver, TiVos and Sat receivers, plus my computer. I use APC and they run about $50 each and are worth every penny spent. APC has a light for a bad ground. If the ground is bad, the light comes on.
