...output transistor, when it goes short the supply is in protection mode, it is pointless reading voltages at this stage, check the transistor located close to the Horizontal output (Flyback) ...
wanted to get some other suggestions on other ideas. Thanks! Absolutely right about the transistor and also check any adjacent resistors to the transformer and to the line output transistor. Good luck
output transistor. Should be two there. Next check the capacitors near the vertical IC, you may have to replace three here. You will need an ESR meter to find these bad capacitors.Resolder any and all
...receiver to a color broadcast station(a colour bar generator can be used to transmit a colour signal to the set). check the Z-axis demodulator, z-axis amplifier and the B-Y output circuit for the ...
...Transistor Optoelectronics Switch Relay". I would check first its condition and also Q 2SC1815 C-931, TH901, R-933, c-410 (470 uf 25V) ,D407 ,R411,because they are straight connected at its ...
...check first if theres an output voltage in the wall outlet. if there is, you have a completely inoperative (dead) set. this symptom is usually caused by a breakdown in the power supply circuit. in ...
...Output transistor. After replacing it the TV functioned great receiving all channels perfectly, except the UHF channels are all off by 51 channels. Channel 20 comes in on channel 71, 24 on 75, 31 on ...
receiver connect directly to the CPU I/O so I would presume there must be voltage always present at the VSS/VCC pins for the power to work. Any ideas for me on what I can check, or further information
...output stage that in turn is not receiving and power from the power supply. The chopper transistor will possibly be short circuit taking the feed resistor with it. Check for dry joints everywhere and ...
