This is a 13yr old tv. The power supply components had been overhauled especially the resistors. All of them had been uprated with higher wattages but values remain the same. The recent expensive mod is replacing the 2 main caps 400v 390uf with 10 pieces of 450v 220uf. The audio board also had been upgraded with 2 pieces of 35v 10000uf caps. The final result is outstanding picture quality especially watching dvds and detail vocals can be heard during broadcasts & dvd movies. This tv is driving 1 pair of Pioneer S-D44V floorstanders. Project date: 25th of July 2006.
