Hi Neil Ummm did this set get hit by lightning??? I find it fascinating that the set will shut down immediately if you hook the antenna to it.... I think your having a problem with a blown safety caps in your isolation circuits and maybe taking care of that problem (safety wise) will allow you to get some better handle on the regulation..... I would think if you were to take a meter and measure between the ground of the antenna cable connector and the RF shield connector, I'll bet you get some wild voltages. just a two bit thought Happy Holidays Bill ----- Original Message ----- From: <tvdoctors@xxxxxxxxxxxxx> To: <Techassist@xxxxxxxxxxxxx> Sent: Tuesday, December 11, 2001 12:51 PM Subject: [TechAssist] RCA PJR500SR > Still having problems with this set. Shuts down within 2 to 3 minutes after turn on. If I hook an antenna to it after turn on I dont have to wait 2 to 3 minutes for the unit to shut down, it shuts down immediately. Checked Voltage reg. (IC901) and it was on 110 volts until set shuts down, then jumps to around 135. I changed the reg. and it still does it. I noticed on the deflection board that diode D708 was missing (looks like someone took it out) I don't know if it's supposed to be there or not. Any help would be appreciated, Thanks Neil > > TV Doctors 108 W.
