A good manual. Had everything i needed to make the repair.
;
This manual is a complete guide, including later additions. It has all the necessary information about the replacement items. The material quality is great to read.
 ;
This manual is very helpful, correct shematic diagram, and good exploded view.Perfect!
;
Alte gescannte Servicepläne sind oft doch etwas undeutlich . Stromlaufpläne werden auf mehrere DIN A4 Seiten aufgeteilt. Alles ziemlich umständlich und zeitaufwendig. Aber mit etwas Mühe geht alles.
;
Great item, high resolution, detailed, very easy to work with.
U4 : EEPROM(24C64) change
3.
When �Tuner connect Fail � Message happens If POWER supplied to Tuner is normalcy , Tuner must change.
4.
When � FLUSH DRAM � Message happens U7(L64005) and U 8(KM416S1020) Re - sold ering do, and change U 7(L64005) if is happened again.
5.
Normal Message as being displayed, change MICOM if TV screen does not come
5.2.2. When �NO SIGNAL� message appears
(1) U19:(KA317(Regulator))
- > pin 3 : 21V~24V
U19:(KA317(Regulator))-> pin 2 : 13V /18V If confirm that voltage is measured and is not measured Action) : When U 19 's( KA317) input voltage is low, , U19 change do you change SMPS,
do U 19 Voltage Line check in SMPS if change SMPS and is low.
(2) Measure by Voltage Meter(Oscilloscope) whethe
r VERTICAL(13Volt) or
HORIZONTAL(18Volt), 22KHz(ON/OFF) is displayed normally measuring voltage of F100's Lead(or Tuner LNB OUT PORT) when do SCAN satellite in INSTALL MENU. (LNB supply voltage check)
(3) When LNB voltage(13V/18V) is not displayed, 13V/18V is displayed measuring Q
it changes Q 27 (TR:kta1273) if 27 's(TR:kta1273) Emitter monad by
Voltage Meter and measure whether 13V/18V is displayed in F100(Poly Switch) Action) : If mania is happened to F100 or Q 27 after shift Tuner shift
(4) Volta ge measurement supplied 1. L13(Coil) : about 5V,
to TUNER
