Hi all I had this set in before for a dead set condition and replaced U4101. this restored normal operation. I now have the set back again for the same problem. I need to know if anyone has the part number for this regulator and any idea's why this may have went out in less than 6 months Thanks for any help Dave Bungard Dave's Electronics Jeannette PA ***************************************************************************** The Tech Address Book: http://www.tech-assist.org/secure/tip/contact.html Add a Repair Tip Here, or Change/Remove your Email Address: http://www.tech-assist.org/secure/tip/main.html Lost Password: http://www.tech-assist.org and select "Lost your Login Info?".
