索尼液晶电视机维修方法大家一定不怎么了解吧,其实不同牌子的电视造成的故障原因一般都有一点差异,关于索尼液晶电视机常见故障维修,具体下面就由快益修来为大家介绍一下关于索尼液晶电视机维修方法。
索尼液晶电视机维修方法1、指示灯不亮解决方法（1）当索尼液晶电视机在开机之后,直接没有光栅,同时也没有声音和伴音出现,它的电源指示灯也不亮,这一故障一般发生在电源电路上。
（2）在进行检修时,需要检查电视机的电源电路,先使用工具打开机盖,检查电视机的电源保险丝是否熔断、电源的滤波电容是不是被C619击穿。
（3）随后用万用表测量时,如果发现IC601第2、3直通,同时进一步检查后,发现C602第1、2脚也被击穿,可以确定电视机自动转换系统故障,需要一个专业的认识进行维修。
2、开机一段时间后黑屏解决方法（1）索尼液晶电视机在开机后,图像显示还正常,但播放一段时间后,就会初心现黑屏现象、但声音、指示灯很正常。
（2）电视机在出现黑屏时,指示灯闪烁10下,说明是电视机高压出现了问题,应该是高压电路发生虚焊,需要进行补焊。
（3）稍后继续检查电视机IC8002外围有无异常状况,若有,需要进行更换新的配件。
3、不定时自动关机解决方法（1）当索尼液晶电视机自动关机时,电源输出电压是35V,可以测量得出各个待机点的电压情况,若正常开机时,一般需要十分钟左右就会自动关机。
（2）检查到过流保护时,发现检测过流保护电阻上的电压会渐渐上升,也会引起过流保护关机,经测量,发现电阻阻值已略为变大了,检测行供电的电流,也是不正常,因此,需更换后试机后,基本上可恢复正常。
之上,索尼液晶电视机维修已经讲解完毕了,对它多少都有点想法,这是情理之中的事情,要是自己不会处理,可通过其它的方式进行维修。
索尼液晶电视机维修有一个细节,都是零件上的损坏,若使用方法正确,可能会延长使用时间,这是猜测,没有理论依据。
快益修承诺作为一个专业的一类维修服务企业,我公司不仅技术维修力量雄厚、维修面广、设备先进、有较为丰富的管理经验,而且特别注重服务质量、服务意识等方面的培训和承诺。
索尼液晶电视还是比较受欢迎的，现在每家每户都有电视机，其中最常见的品牌就是索尼了，而且电视我们使用频率也是很高的，时间久了。
就可能出现一些故障问题。
这个时候就需要进行维修处理，下面就给大家简单介绍一下常见的故障以及维修方法一、电视机突然无信号：解决方法：此故障分为二种情况，第一通电后出现无输入信号;第二通电后出现超出显示。
(1)出现无输入信号时，应检查信号电缆连接是否正常;检查主板由行场输入到反相器输出再到主芯片部份电路有无虚焊/短路现象;检查主板各工作点电压是否正常。
(2)出现超出显示时，应检查计算机输入信号是否超出范围;检查主板各个工作点的电压。
二、电视机有声音无图像：原因：首先怀疑是高频头出了问题,这会直接导致这个情况。
还有是色彩制式没有调整对,没有调节到亮度出来,通过遥控器调整色彩制式检查。
解决方法：(1)高频头损坏之后,是没有图像的输入的,所以电视机屏幕上面是没有图像显示,检查高频头的相关参数是否正常,再进行更换。
(2)调整电视机的色彩制式,这也是引起的原因之一,通常这种情况是比较少的。
关掉电视的时候,在关的一瞬间可以看到电视机的光亮,而且是有一点放电的声音,那么可以断定的是电视机的显像管是正常的。
三、电视机画面闪：解决方法：出现此故障时，用自动或手动调节“相位”能否调好;检查主板各个工作点的电压是否正常;检查锁相回路电容、电阻有无变值;检查主板由行场输入到反相器输出再到芯片部分电路有无虚焊、短路现象。
四、电视机磁化磁化原因：电视机受过剧烈振动、电视机内部的消磁电阻损坏、受旁边带磁物体的磁化影响、电视机里面的偏转线圈或色纯磁环移位解决方法：受到剧烈震动之后的电视机,会出现更多的情况,也不能确定是元件的损伤还是人为的因素。
要请专业的维修人员进行修理,如果是画面能够显示,除了有屏幕的光晕现象一切正常,那么就用专业的消磁器就能够解决。
五、电视机整机没有电整机无电原因：这是一个很简单的故障,主要是由电视机的机内电源和机外电源两种情况造成的。

SAFETY-RELATED COMPONENTWARNING!!Replace all components with Sony parts whose part numbers appear as shown in this manual or in supplements published by Sony.WARNINGS AND CAUTIONSSAFETY-RELATED COMPONENTWARNINGIt is essential that all critical parts be replaced only with the part number specified in the electrical parts list to prevent electric shock, fire, or other hazard.NOTE:Do not modify the original design without obtainingwritten permission from the manufacturer or you will void the original parts and labor guarantee.USE CAUTION WHEN HANDLING THE LCD PANEL When repairing the LCD panel, be sure you are grounded by using a wrist band.When repairing the LCD panel on the wall, the LCD panel must be secured using the 4 mounting holes on the rear cover.1)Do not press on the panel or frame edge to avoid the risk ofelectric 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 ofhigh 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 withinthe 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 handling the wires or connectors of the invertercircuit. Damaging the wires may cause a short.9)Protect the panel from ESD to avoid damaging the electroniccircuit (C-MOS).SAFETY CHECK-OUTAfter 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 poorlysoldered connections. Check the entire board surface forsolder 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, particularlytransistors, 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 obvioussigns of deterioration. Point them out to the customer andrecommend their replacement.6.Check the line cords for cracks and abrasion. Recommendthe 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 ACleakage. Check leakage as described below.Leakage TestThe AC leakage from any exposed metal part to earth ground and from all exposed metal parts to any exposed metal part having a return to chassis, must not exceed 0.5 mA (500 microamperes).Leakage current can be measured by any one of three methods.1. A commercial leakage tester, such as the Simpson 229 orRCA WT-540A. Follow the manufacturers’ instructions touse these instructions.2. A battery-operated AC milliampmeter. The Data Precision245 digital multimeter is suitable for this job.3.Measuring the voltage drop across a resistor by means of aVOM or battery-operated AC voltmeter. The “limit”indication is 0.75 V, so analog meters must have an accurate low voltage scale.The Simpson’s 250 and Sanwa SH-63TRD are examples of passive VOMs that are suitable. Nearly all battery-operated digital multimeters that have a 2 V AC range are suitable (see Figure A).How to Find a Good Earth GroundA cold-water pipe is a guaranteed earth ground; the cover-plate retaining screw on most AC outlet boxes is also at earth ground. 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.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 B).FigureA. Using an AC voltmeter to check AC leakage. Figure B. Checking for earth ground.SELF DIAGNOSIS FUNCTIONThe units in this manual contain a self-diagnostic function. If an error occurs, the STANDBY 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 STANDBY 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.1-1.DIAGNOSTIC TEST INDICATORSWhen an error occurs, the STANDBY 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 .Number of times STANDY LEDMonitoring Items Diagnostic Item Description(Red) flashes (Screen Display)2 times DC_DET Main power supply voltage error (12V, etc)3 timesDC_ALERT1Malfunction of 3.3V line (Trident circuit, etc)4 times DC_ALERT2Malfunction of 5V line(Voltage Supply to FE, etc)5 times DC_ALERT3Malfunction of power supply for screen6 times BACKLIGHT Malfunction of inverter or overcurrent, etc7 times TEMPERATURE Abnormal temperature inside unit8 times AUDIO Audio circuit error (amplifier, etc.)9 times AUSD FAN Fan malfunction10 times DEFDigital FE circuit error11 times B-ENGINE Malfunction of Trident IC or around IC 12 times HFRBH board error 13 times(No item on screen display)Malfunction of balancer1-2.DISPLAY OF STANDBY/TIMER LIGHT FLASH COUNT1-3.STOPPING THE STANDBY FLASHTurn off the power switch on the TV main unit or unplug the power cord from the outlet to stop the STANDBY LED from flashing.2 times4 times5 timesLED ON 0.3 sec.[ FLASH COUNT ]Note: One flash counts is not self-diagnostic.1-4.SELF-DIAGNOSTIC SCREEN DISPLAYFor errors with symptoms such as “power sometimes shuts off” or “screen sometimes goes out” that cannot be confirmed, it is possible to bring up past occurrences of failure for confirmation on the screen:1-4-1.To Bring Up Screen TestIn standby mode, press buttons on the remote commander sequentially in rapid succession as shown below:Since the diagnostic results displayed on the screen are not automatically cleared, always check the self-diagnostic screen After you have completed the repairs, clear the result display to “0”.1-5.Quitting Self-diagnostic screenTo quit the entire self-diagnostic screen, turn off the power switch on the remote commander or the main unit.* : Note that this differs from entering the service mode (volume +)Monitoring ItemsError Count RecordFor details, refer to "1-1.
