LC-10A3U SUPPLEMENT SERVICE MANUAL SX2T7LC-10A3U SUPPLEMENT LCD COLOR TELEVISION MODEL LC-10A3U In the interests of user-safety (Required by safety regulations in some countries) the set should be restored to its original condition and only parts identical to those specified should be used. OUTLINE A Mark The 10" LCD panel used in the LC-10A3U has been redsigned as from the October 2002 production. Accordingly, the circuitly, LCD panel and its peripheral parts have been partially changed.
LC-10A3U SUPPLEMENT IMPORTANT SERVICE SAFETY PRECAUTION Ë Service work should be perfomed only by qualified service technicians who are thoroughly familiar with all safety checks and the servicing guidelines which follow: • Use an AC voltmeter having with 5000 ohm per volt, or higher, sensitivity or measure the AC voltage drop across the resisor.
LC-10A3U SUPPLEMENT PRECAUTIONS A PRENDRE LORS DE LA REPARATION Ë Ne peut effectuer la réparation qu' un technicien spécialisé qui s'est parfaitement accoutumé à toute vérification de sécurité et aux conseils suivants. • Utiliser un voltmètre CA d'une sensibilité d'au moins 5000Ω/V pour mesurer la chute de tension en travers de la résistance.
LC-10A3U SUPPLEMENT Precautions for using lead-free solder 1 Employing lead-free solder "Main PWB" of this model employs lead-free solder. The LF symbol indicates lead-free solder, and is attached on the PWBs and service manuals. The alphabetical character following LF shows the type of lead-free solder. Example: LFa Indicates lead-free solder of tin, silver and copper. 2 Using lead-free wire solder When fixing the PWB soldered with the lead-free solder, apply lead-free wire solder.

LC-10A3U SUPPLEMENT ADJUSTING PROCEDURE OF EACH SECTION The best adjustment is made before shipping. If any position deviation is found or after part replace is performed, adjust as follows. 1. Preparation for Adjustments (1)Use the exclusive-use AC adapter or stable DC power supply. AC adapter: UADP-0227CEPZ DC power supply: 12 ± 0.5V 2. Special mode setting procedure (1)After initialization of E2PROM the mode is changed to the adjustment mode.
LC-10A3U SUPPLEMENT 4. Reset of lamp error If the power LED remains red an the power is not turned on, or if repair has been performed, enter the adjustment mode to reset the lamp error. For the resetting procedure, refer to "No power" in the "trouble shooting Table" section. 5. Adjustments Adjustment Adjusting conditions Adjusting method 1 B+ Adjustment (If E2PROM is replaced) (IC2004) 1. Connect the DC voltmeter to pin (49) 1. Adjust the "B+ Adj" value to of SC401. 5.0 ± 0.
LC-10A3U SUPPLEMENT Adjustment Adjusting conditions 5 White balance adjustment 1. Receive the monoscope pattern signal. 2. Adjust the "RCUTOFF" and "BCUTOFF" settings on the page 2 of the adjustment process mode to become the proper white balance. Do not change the "GCUTOFF" settings. (It also change the black level.) 6 Checking and modifying the settings (If E2PROM is replaced) 1. Go to the adjustment mode and check the following settings.
