Mike, Many tips for this model in the Tech Repair CD..you haven't renew, so you may not have these. Panasonic\CT32HX41\intermittently shutdown and must be unplugged before it will turn on again\\\\Arcing at the CRT pins and/or spark gap causes the unit to shutdown. This is more likely to occur at high altitude areas (several thousand feet above sea level).\Replace CRT socket connector with improved part number\\\\\\\
Panasonic\CT32HX41\Shuts down\Faulty components in the ABL circuit cause increased beam current to trigger shutdown circuit\Arcing at CRT connector and/or spark gap causes shutdown.\\1. Troubleshoot ABL circuit and check components listed below. Check C524 and R517. 2. Clean CRT pins and/or replace CRT socket connector (part number TJSC01800)\\\\\\\\ Panasonic\CT36HX41E\Intermittent shutdown\\\DX2\Check C524* L875* & R517\\\\\\\\ Panasonic\CT32HX41\Troubleshooting Tips\Check the ABL circuit to confirm if it is the cause of the problem. 1. Apply a full white field or large window pattern with high white.\2. Lift Diode D837 to disable140V line short protect feedback circuit to MPU SOS pin. 3. Short pin 3 of flyback T551 to ground.\Observe any change in white level. If there is no change in brightness the ABL circuit is faulty.\Check components: C524* R517* D509* D510* R514* R515* R516* and C525 on the HX series models) If the white level increases* then ABL is OK\Troubleshoot other protection circuits. For HX series: check D837* D835* D841* D401* D409* D894* IC2505 For SX series: check D837* D835* D841* IC101* R246. ??\Other causes for intermittent shutdown are arcing and/or oxidation of the CRT connection pins. Remove the CRT drive board and clean the CRT pins with a wire brush or steel\In addition* check the spark gap on the CRT socket. Remove the 2 focus wires (orange and white cable) by pulling the tab* then pull the 2 side clips from the\socket cover and inspect the spark gaps. If they appear abnormal* replace the CRT socket. (Part number: TJSC01800). Note: a protection circuit being triggered\usually causes intermittent shutdown problems. The suggestions above are two of the most frequent causes for shutdown* but certainly not the only causes\\\ Panasonic\CT36HX41E\Shuts down in a few seconds. High Voltage tries to come up\\\DX2\Check D836\\\\\\\\ Jeff -- Intrepid Video TV/VCR Repair 263 S Front St, Steelton PA 17113 717-939-7708; (F) 717-564-4952 www.intrepid-video.com www.tech-repair.net ----- Original Message ----- From: "mgodar" <[EMAIL PROTECTED]> To: <[email protected]> Sent: Tuesday, December 28, 2004 8:42 PM Subject: [Techs] Pannasonic ct36hx41e intermintent shutdown Hello This set shuts down after on for an hour or so. Unplug and the set and it will come back on and play again for an hour. Same problem repeats. Checked all connections in Horz,HV and Power supply sections.Can not take any voltage measurements when the set is shut down.Something is causing this set to shut down. Have not seen the pix when this happens. Tryed heat gun in all the areas including the crt board.Anyone experience this problem on this Direct view HDTV set?> Thank You Mike GODAR ELECTRONICS WORLD CLASS ANTENNA MANUFACTURER http://users.mcleodusa.net/m/mgodar Electronics service Div 339 North Gilbert rd Gilbert AZ 85234 (480)892-8207 _______________________________________________ Tech Repair CD...order your just $49.00 plus shipping...One year of updates free. www.intrepid-video.com www.tech-repair.net Techs mailing list [email protected] http://intrepid-video.com/mailman/listinfo/techs_intrepid-video.com _______________________________________________ Tech Repair CD...order your just $49.00 plus shipping...One year of updates free. www.intrepid-video.com www.tech-repair.net Techs mailing list [email protected] http://intrepid-video.com/mailman/listinfo/techs_intrepid-video.com
