Remedy: Remove tuner and repair defective ground connections to frame and circuit board. ------------------------------------------------------------------ Model No.: cep 1497e Fault: descintonia :intermitente Remedy: ver.transistor Q105 JC501R ------------------------------------------------------------------ Model No.: CEP3032TX Fault: blows hot and c361 because B+up to 240V Remedy: replace r355 47k 0,5W in the voltage stabilizing circuit ------------------------------------------------------------------ Model No.: DS19130 Fault: Approx.4'' of vert.defl.in center of screen. Remedy: Replaced C452(1uF/50v.)Located near vert. out. chip ------------------------------------------------------------------ Model No.: DS19230 Fault: No Sound. Remedy: Replaced IC101(LA7655N)crosses to NTE/ECG 1863. VIF/SIF Vcc(Approx. 9v) on pin 9. AF output was missing from pin 4. ------------------------------------------------------------------ Model No.: DS19230 Fault: No vertical deflection. Remedy: Replaced R746(3.9 1/2w.)was open,located behind flyback. Vert. out.chip was o.k. ------------------------------------------------------------------ Model No.: DS19230 Fault: Vertical collapse W/vert. lines at top Remedy: Replace C452(1UF@50 Volts)This cap was thermal,spray W/freeze spray pic.would come back for about 20 seconds. ------------------------------------------------------------------ Model No.: DS19430 Fault: CH 2 through 6 very snowy,CH 7 and up was o.k Remedy: Replaced tuner. ------------------------------------------------------------------ Model No.: DS20030 Fault: Insufficient vertical deflection Remedy: Replace defective capacitor C452 (1uf 50v.) ------------------------------------------------------------------ Model No.: DS20030 Fault: SNOW, LOOKS LIKE BAD TUNER Remedy: REPLACE D521, 5.6V ZENER DIODE ------------------------------------------------------------------ Model No.: DS20930 Fault: Goes dead/pic.draws in when changing channels Remedy: Replaced B+ Reg.(STR30135). ------------------------------------------------------------------ Model No.: DS25030 Fault: Top vert. foldover w./white lines(1/2 screen) Remedy: Replaced R454(5.6k 1/4w.) This resistor had increased to 17.2k ohm,and is located near the yoke plug on the chassis.I replaced with 5.6k ohm 1/2w. ------------------------------------------------------------------ Model No.: DS25031 Fault: 1)Dead Set. 2)Unclear(audio)talk. Remedy: Replaced fuse,B+Reg.Resistor(5.6 2w.), and the Yoke.The yoke was burned on the inside. 2)Replaced R608(680 ohm/3w.),this resistor is located behind the B+Reg.on the board. After replacing R608 the talking was returned to normal. ------------------------------------------------------------------ Model No.: KVM2751 Fault: Dead Set-- No relay action. Remedy: Replaced Q052. ------------------------------------------------------------------ Model No.: MODEL#AVM 2001 Fault: NO VERTICAL DEFLECTION. Remedy: FOUND THE FALLOWING.OPEN RESISTOR R 476=3.9~1/2W.FAULTY IC451(LA7837).ALSO DRIED UP CAPACITOR C456=220UF/35V. ------------------------------------------------------------------ VIDEO ------------------------------------------------------------------ Model No.: VHR 9413A Fault: Occasionally doesn't retract tape fully into cassette when ejecting. Remedy: Check brake shoe pad near capstan motor for sticky/glazed appearance and replace ------------------------------------------------------------------ Model No.: VHR287E Fault: Patterning on e - e. Remedy: PR 512 was high in resistance. upgrade this to a 1.25 amp. ------------------------------------------------------------------ Model No.: VHR2900 Fault: Player accepts tape, pinch rollers go to full extention - then returns to stop position. Tape lays in unit and there is no motor movement. Remedy: Verify all volts on STK5482 power regulator. I assume that, you may need to change it. ------------------------------------------------------------------ Model No.: vhr3300 Fault: Blank screen with white bands in any mode Remedy: Change the la7223 ------------------------------------------------------------------ Model No.: VHR3300E Fault: DEAD NO DISPLAY Remedy: R1 IN THE POWER SUPPLY WAS OPEN CIRCUIT ------------------------------------------------------------------ Model No.: VHR5406 Fault: Will not operate with remote control. Remedy: Replaced IR pick-up amp.(eye) assembly located on the front panel of the vcr ------------------------------------------------------------------ Model No.: VHR-9421 Fault: Blue screen during normal playback in both SP & EP speeds. Picture visible during forward/rewind search and pause/frame by frame functions. Remedy: At first, one would think dirty or bad video heads, but after cleaning, no change occured. Real problem stemmed from cold solder joints on the small pcb on the back of the ctl head. Just re-solder and video is restored. ------------------------------------------------------------------ Model No.: VHR-D4710 Fault: A mecânica trabalha aos soluços lentamente Remedy: C5102(100Uf25v)na fonte.Depois do secundário do transformador. I translate if necessary. ------------------------------------------------------------------ Model No.: VHR-9600 Fault: No functions other that cassette loading. Remedy: Kolla efter broken brake shoe post. Reparera genom att skruva i fina thread skruvar in it's place ------------------------------------------------------------------
