My week for Dogs
model 19GT243
chassis TX808r
Oct. 2000
Dead
Found Shorted DP27, Zener in Primary BZX55B24,which I think is a 24v Zener.
Found Shorted DP90, Rectifier in Secondary BYW100-200,which I think is a
NTE587.
I replaced these parts but set is Still Dead.
DP90 may have an open Resistor RP90,between it and pin 10 of the SM PS
Transformer.
I say may have because it looks more like a Capacitor.
Markings on this part are MP160.
No PS Secondary Voltages.
Raw 160v is at Regulator(2SK2662),but looks no 'Turn-on' Drive is there.
HOTransistor is good.
No Schematics.
Anybody worked on one of these,or have the manual ???
