Very good service Within one day i received a pdf of the users manual and electric circuits so I was able to measure the different voltages in the printed circuit and find out the fault Payment was also reliable and easy.Without the manual i could not have repaired.So thanks to "Search for a manual"
 ;
you are doing great job guys.....my father ask me to find out the schematics of Sony KV25R1D to sort out the problem ..(he was electrical technician, and excperianced with TV and simillar stuff). finally he found the cause and change all necessary parts....now he has got working old dog..and is very happy!!... thank you all.. NB..he also saved the repair cost.

Perfect. Received my manual within 24 hours. Clear scan of the manual I needed. No problem.

DESCRIPTION OF SCHEMATIC DIAGRAM
SAFETY NOTE: 1. DISCONNECT THE AC PLUG FROM THE AC OUTLET BEFORE REPLACING PARTS. 2. SEMICONDUCTOR HEAT SINKS SHOULD BE REGARDED AS POTENTIAL SHOCK HAZARDS WHEN THE CHASSIS IS OPERATING. IMPOTANT SAFETY NOTE: PARTS MARKED WITH « ! » ( ) ARE IMPORTANT FOR MAINTAINING THE SAFETY OF THE SET. BE SURE TO REPLACE THESE PARTS WITH SPECIFIED ONES FOR MAINTAINING THE SAFETY AND PERFORMANCE OF THE SET.
NOTE: 1. The unit of resistance «ohm»is omitted (K=1000 ohms. M= Megaohm). 2. All resistors are 1/8 watt. unless otherwise noted. 3. All capacitors are µF, unless otherwise noted (P=
µµF).
4. The capacitor with Part No. RC-FZ9XXXBMNJ is designed to with stand 63V. 5. The capacitor with Part No. RC-FZ4XXXBMNJ is designed to with stand 50V.
SERVICE PRECAUTION: THE AREA ENCLOSED BY THIS LINE ( ) IS DIRECTLY CONNECTED WITH AC MAINS VOLTAGE. WHEN SERVICING THE AREA, CONNECT AN ISOLATING TRANSFORMER BETWEEN TV RECEIVER AND AC LINE TO ELIMINATE HAZARD OF ELECTRIC SHOCK. WAVEFORM MEASUREMENT CONDITION: Colour bar genetator signal of 70 dB from RF input.
