4 SECTION 1 SAFETY NOTES
1-1. Warnings and Caution 1-2. Caution Handling of LCD Panel 1) These servicing instructions are for use by qualified service personnel only. When repairing the LCD Panel, make sure you are grounded with a wrist band. 2) To reduce the risk of electric shock, do not perform any servicing other than When repairing the LCD Panel on the wall, the panel must be secured using the that contained in the operating instructions unless you are qualified to do so. 4 mounting holes on the rear cover. 3) An isolation transformer should be used during any service to avoid 1) Do not press the panel or frame edge to avoid the risk of electric shock. Possible shock hazard, because of live chassis. The chassis of this receiver is 2) Do not scratch or press on the panel with any sharp objects. directly connected to the ac power line. 3) Do not leave the module in high temperature or in areas of high humidity for 4) Be sure to follow these guidelines to protect your property and an extended period of time. avoid causing serious injury : 4) Do not expose the LCD panel to direct sunlight. • Carry the TV with an adequate number of people; larger size TVs require two or more people. 5) Avoid contact with water. It may cause short circuit within the module. • Correct hand placement while carrying the TV is very important for 6) Disconnect the AC power when replacing the backlight (CCFL) or safety and to avoid damages. inverter circuit. (High voltage occurs at the inverter circuit at 650Vrms) 5) Components identified by shading and ! mark on the exploded views, 7) Always clean the LCD panel with a soft cloth material. and in the parts list are critical for safe operation. Replace these components with Sony parts whose part numbers appear as shown in this 8) Use care when handling the wires or connectors of the inverter circuit. manual or in supplements published by Sony. Circuit adjustments that are Damaging the wires may cause a short circuit. critical for safe operation are identified in this manual.

Replace only with (To protect electric shock when customer touch the terminal.) the same or equivalent type. Leakage current can be measured by V: Voltmeter or oscilloscope (r.m.s. or 2) Outer case broken battery should not contact to water. peak reading) Stabilized power supply instrument and isolated voltage transformer: 1-4. Safety Check-Out Use too much current capacity and isolated voltage transformer does not After correcting the original service problem, perform the following need to use stabilized power supply equipment. safety checks before releasing the set to the customer:- Specification of RMS volt meter: Input resistance > 1 Mohm, Input capacitance < 200 pF, Frequency range: 15 Hz – 1MHz . Refer Figure 1. 1) Check the area of your repair for unsoldered or poorly soldered Isolated type volt -meter (FLUKE 8921A etc *1) connections. Check the entire board surface for solder splashes and bridges. *1 Not use FLUKE 8920A that connected to protective earth by diode 2) Check the inter board wiring to ensure that no wires are pinched or # Leakage current of measurement instrument is less than 10μArms when contact high-wattage resistors. under test equipment AC plug is opened 3)Check all control knobs, shields, covers, ground straps and mounting # Set up the following condition and turn on the set. Applied voltage: hardware have been replaced. Be absolutely certain you have replaced all Nominal input voltage (Description on Nameplate) the insulators. # Measure the leakage current between one phase conductor and neutral 4) Look for unauthorized replacement parts, particularly transistors that for terminal 1 and terminal were installed during a previous repair. Point them out to the customer and 2. Read rms value, and then calculate to peak value PEAK VALUE =√2 recommend their replacement. RMS VALUE 5) Look for parts which, though functioning show obvious signs of Comply with the following requirement deterioration. Point them out to the customer and recommend their Class II equipment (2-pin plug): for each terminal, the worst value of replacement. measurement must not exceed AC 283uA peak). 6) Check the line cords for cracks and abrasion. Recommend the Note: including AC adaptor, AC adaptor/DC operated unit combination replacement of any such line cord to the customer. Note: Products which are always used in touch with human body: 141uA 7) Check the antenna terminals, metal trim, metalized knobs, screws and all (peak) other exposed metal parts for AC leakage. Check leakage test as described Note: As for products destined for Southeast Asia (Rod Antenna is next. accessory. Or it is packed with a product.), the worst value must not exceed 8. For safety reasons, repairing the Power board and/or Inverter board is AC 141uA (peak). prohibited. Figure 1 – Measuring network for Leakage Current

1-6. How to Find a Good Earth Ground 1-8. Handling the FLEXIBLE FLAT CABLE (FFC) 1) A cold-water pipe is a guaranteed earth ground; the cover-plate retaining When you insert / pull out FFC, please grasp a reinforcement board and main screw on most AC outlet boxes is also at earth ground. body of FFC. 2) If the retaining screw is to be used as your earth ground, verify that it is at ground by measuring the resistance between it and a cold-water pipe with an ohmmeter. The reading should be zero ohms. 3) If a cold-water pipe is not accessible, connect a 60- to 100-watt trouble- light (not a neon lamp) between the hot side of the receptacle and the retaining screw. Try both slots, if necessary, to locate the hot side on the line; the lamp should light at normal brilliance if the screw is at ground potential (see Figure 3).

1-7. Lead Free Information The circuit boards used in these models have been processed using Lead Free Solder. The boards are identified by the LF logo located close to the board designation.
Figure 4: LF Logo Figure 5: LF logo on circuit board
The servicing of these boards requires special precautions. It is strongly recommended to use Lead Free Solder material in order to guarantee optimal quality of new solder joints.

9 SECTION 2 SELF DIAGNOSTIC FUNCTION
The units in this manual contain a self-diagnostic function. If an error occurs, the Smart Core Red LED will automatically begin to flash. The number of times the LED flashes translates to a probable source of the problem. A definition of the Smart Core Red LED 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.
DIAGNOSTIC TEST INDICATORS When an error occurs, the Smart Core Red LED will flash a set number of times to indicate the possible cause of the problem. If there is more than one error, the LED will identify the first of the problem areas. Result for all of the following diagnostic items are displayed on screen. If the screen displays a “0”, no error has occurred .

Press and hold down the power button (approx. 5 seconds) on the remote commander until the message “Power off” appears on the TV screen 2. The TV will turn off, and then restart automatically Try a reset when Android TV doesn’t behave properly (e.g., the TV is unresponsive or is stuck on a black screen). Note if you unplug and plug in the power cable, it may have the same effect as a reset. If a reset does not resolve the problem, try a new software update and or a factory reset. Important: This reset will not delete any personal settings, data and downloaded apps on the TV. Factory reset: 1. From Home Screen, select [Settings] 2. Select [TV] [Storage & reset] [Factory data reset] [Erase everything] 3. Select “YES“ Important: The factory reset will delete all personal settings, data and downloaded apps on the TV. Tip: We recommend creating a backup of the channel list onto a USB stick. This will allow to easily restore the channel list after performing a factory reset. The following steps detail how to back up the channel list: 1. Connect the USB device to the TV so as to import/export the list of tuned programmes 2. From Home Screen, select [Settings] 3. Select [TV] [Channel setup] → [Digital setup] → [Technical Set-up] → [Programme List Transfer], then select [Import] or [Export] 4. Follow the on-screen instructions to complete transfer Force Factory reset: 1. Unplug the power cable from the outlet 2. Press and hold down both the “Center” and “Down” keys located on the TV 3. Plug the power cable back in the outlet (while holding down both the “Center” and “Down” keys) Important: The factory reset will delete all personal settings, data and downloaded apps on the TV. : Speaker Temp. sensor I2C No ACK [TEMP_ERR] : Power Adapter, : Speaker : Power Adapter, AUD_ERR_I2C None
