I am so happy found this site as it consists of so many Manuls and easy to aquire. This onei s exactly what I wanted and much more as it has info on not only how to use the tuner but how to repair it as well. I will come here 1st before purchasing else where! Thanks owner-manual.com!
Top class product, I printed it out on A3 paper and it is clear and very easy to follow.
Cheaper than buying a new radio!
is part of the manual is very useful for repairing
Here are circuit diagrams
if there is damage, I recommend using this part of the
a complete list of circuit boards and components
[PWD signal] After plug the AC cord into outlet, VP voltage appears on the base terminal of transistor Q3. When the VP exceeds 16 volts, Q3 is turned on by the differential voltage between base and emitter terminal of transistor Q3. Then the PWD signal goes to GND level and informes â Power ON â to the CPU. When the VP drops less than 16 volts, Q3 is turned off. Then the PWD goes high level since the PWD is pulled up to VDD. When the CPU receives â High â signal of PWD, CPU goes to â Power failure process â. Note : During plug the Ac cord into outlet, all voltages are supplied to the PCB. If you open the machine for repair, make sure plug off. [Location for voltage check points] Actual value on the E259-1 PCB (unitV)
