KV-2199XDK RM-952 SELF DIAGNOSTIC FUNCTION The units in this manual contain a self-diagnostic function. If an error occurs, the STANDBY/TIMER lamp will automatically begin to flash. The number of times the lamp flashes translates to a probable source of the problem. A definition of the STANDBY/TIMER lamp flash indicators is listed in the instruction manual for the user's knowledge and reference. If an error symptom cannot be reproduced, the remote commander can be used to review the failure occurrence data stored in memory to reveal past problems and how often these problems occur. 1. DIAGNOSTIC TEST INDICATORS When an errors occurs, the STANDBY/TIMER lamp will flash a set number of times to indicate the possible cause of the problem. If there is more than one error, the lamp will identify the first of the problem areas. Result for all of the following diagnostic items are displayed on screen. No error has occured if the screen displays a "0". Diagnostic Item Description · Power does not turn on No. of times Self-diagnostic STANDBY/TIMER display/Diagnostic lamp flashes result Does not light -- Probable Cause Location · Power cord is not plugged in. · Fuse is burned out F4601 (F) · H.OUT Q511 is shorted. (A board) · IC701 is shorted. (C3 board) · -13V is not supplied. (A board) · IC 503 faulty (A board) Detected Symptoms · Power does not come on. · No power is supplied to the TV. · AC power supply is faulty. · Power does not come on. · Load on power line is shorted. · Has entered standby state after horizontal raster. · Vertical deflection pulse is stopped. · Power line is shorted or power supply is stopped. · No raster is generated. · CRT cathode current detection reference pulse output is small. · +B overcurrent (OCP) or overvoltage (OVP) · Vertical deflection stopped · Horizontal deflection overdrive · White balance failure (no PICTURE) 2 times 002:000 or 002:001~255 003:001~255 004:001~255 at the same time 5 times 005:000 or 005:001~225 · G2 is improperly adjusted. (Note 2) · CRT problem. · Video OUT IC701 is faulty. (C3 board) · IC301 is faulty. (A board) · No connection A board to C3 board. · Discharge CRT (C3 Board) · Static discharge · External noise · Micro reset -- 101:00 or 101:001~225 · Power is shut down shortly, after this return back to normal. · Detect Micro latch up. Note 1: If a + B overcurrent is detected, stoppage of the vertical deflection is detected simultaneously. The symptom that is diagnosed first by the microcontroller is displayed on the screen. Note 2: Refer to screen (G2) Adjustment in section 3-4 of this manual. ­4­ KV-2199XDK RM-952 2. DISPLAY OF STANDBY/TIMER LIGHT FLASH COUNT 2 times 5 times Lamp ON 0.3 sec. Lamp OFF 0.3 sec.
