These servicing instructions are for use by qualified service personnel only.
To reduce the risk of electric shock, do not perform any servicing other than that contained in the operating instructions unless you are qualified to do so.
An isolation transformer should be used during any service to avoid possible shock hazard, because of live chassis.
The chassis of this receiver is directly connected to the ac power line.
Be sure to follow these guidelines to protect your property and avoid causing serious injury.
•Carry the TV with an adequate number of people; larger size TVs require two or more people.
•Correctthanddplacementtwhile carrying thethTVis very importanttfortsafetyfandt toavoidt damagesid.
Components identified by shading and ! mark on the schematic diagrams, exploded views, and in the parts list are critical for safe operation. Replace these components with Sony parts whose part numbers appear as shown in this manual or in supplements published by Sony. Circuit adjustments that are critical for safe operation are identified in this manual. Follow these procedures whenever critical components are replaced or improper operation is suspected.
•Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type.
•Outer case broken battery shouldldnot contactt t tto water.

WARNINGS AND CAUTIONS
When repairing the LCD panel, be sure you are grounded by using a wrist band.
When repairing the LCD panel on the wall,allthetheLCDpanelmuststbebesecuredusingthe44mountingnting holesononthetherearrearcocover.
1)Do not press on the panel or frame edge to avoid the risk of electric shock.
2)Do not scratch or press on the panel with any sharp objects.
3)Do not leave the module in high temperatures or in areas of high humidity for an extended period of time.
4)Do not expose the LCD panel to direct sunlight.
5)Avoid contact with water. It may cause a short circuit within the module.
6)Disconnect the AC power when replacing the backlight (CCFL) or inverter circuit. (High voltage occurs at the inverter circuit at 650Vrms.)
7)Always clean the LCD panel with a soft cloth material.
8)Use care when handlinggthe wires or connectors of the inverter circuit. Damagingtheg wires may causey a short.
9)Protect the panel from ESD to avoid damaging the electronic circuit (C-MOS).
10)It is recommended not to exceed 1 hour of Power-On nor Burn-in period with LCD panel face down condition, in repair activity.

After correcting the original service problem, perform the following safety checks before releasing the set to the customer:
1.Check the area of your repair for unsoldered or poorly soldered connections. Check the entire board surface for solder splashes and bridges.
2.Check the interboard wiring to ensure that no wires are “pinched” or touching high-wattage resistors.
3.Check that all control knobs, shields, covers, ground straps, and mounting hardware have been replaced. Be absolutely certain that you have replaced all the insulators.
4.Look for unauthorized replacement parts, particularly transistors, that were installed during a previous repair. Point them out to the customer and recommend their replacement.
5.Look for parts which, though functioning, show obvious signs of deterioration. Point them out to the customer and recommend their replacement.
6.Check the line cords for cracks and abrasion. Recommend the replacement of any such line cord to the customer.
7.Check the antenna terminals, metal trim, “metallized” knobs, screws, and all other exposed metal parts for AC leakage. Check leakage as described below.
8.For safety reasons, repairing the Power board and/or Inverter board is prohibited.

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. |
