长虹彩电+B 滤波电容失容所引起的三无例1， 一台长虹D2521彩电三无，测+B 电压只有40V 左右，断开负载，电压上升到80V 。
这说明故障在电源本身，更换+B 电容160V/470μF 故障排除。
例2， 一台长虹G2109A 彩电三无，测+B 电压只有24V 左右，遥控开机电压不变，听用户反映开始时拍机壳还能开机，于是重点检查看有无接触不良，最后发现+B 电容C561脱焊，补焊后故障排除。
例3， 一台长虹H29K60彩电三无，待机电压85V ，开机后下降到只有70V 左右，断开负载仍然如此，这和过流保护电阻R803阻值增大的现象类似，检查R803正常，更换N831（SE113）也不能排除故障，检查+B 电容C833，发现已没有容量，更换之，故障排除。
长虹彩电无规律自动关机维修案例例1，一台长虹D2521彩电无规律自动关机。
修长虹TDA 机芯自动关机，首先要分清是哪部分电路引起的，是电源部分还是扫描部分。
这可通过断开交流开关连线来判断：当自动关机时，若无+B 电压，多为电容C820（50V/4.7μ），C814（50V/47μ）容量下降，导至+B 电压升高电源自动保护所至。
若+B 电压正常，故障在扫描部分，先观察灯丝是否点亮，灯丝亮，说明行扫描正常，故障多为V412性能不良，使12V 电压降低引发自动关机。
如果灯丝不亮，则多为行推动变压器接触不良引起的。
例2，一台长虹R2118AE 彩电工作30分钟左右自动关机。
检修：当故障出现时测+B 电压为待机状态，测量CPU ⑦脚电压为高电平，说明CPU 已经发出关机指令，断开V576集电极+B 电压上升为130V ，显像管灯丝亮，只是黑屏。
修长虹A6机芯自动关机，还要注意到CPU 的○41脚电压，正常时应为4.5V 以上。
这是测量只有1.7V 。
该脚是过流保护检测输入：当12V ，7.8V ，25V 任意一路出现短路情况，该脚电压将降低，使CPU 发出关机指令。

2．CH05T1609、CH05T1623，1631三者间可以相互代换,但代换时,应注意：使用CH05T1609芯片时，主板上C171容量应为1200PF；使用CH05T1623芯片时,主板上C171容量应为3900PF。
3．CH05T1609、CH05T1623与CH05T1602、CH05T1604、CH05T1607不能互换，因为两者间软件截然不同，前者为飞利浦软件，后者为四川长虹统一软件.4．CH05T1601与CH05T1603可以相互代换，但要注意以下几点：①CH05T1601应对应TDA9383“N2H”版本（IC表面最下面中间有“N2H”字样），同时相关元件位号、型号对应如下：R171-0。
166W/2。
7KΩ；C171-63V/4700PF；C171A-63V/820PF；②CH05T1603对应TDA9383“N2I"版本(IC表面最下面中间有“N2H”字样),同时相关元件位号、型号对应如下：R171—0。
166W/3.9K Ω;C171-63V/1200PF；C171A—63V/330PF。
③CH05T1601与CH05T1603互换，需更换外围元件；④用CH05T1601或CH05T1603代换TDA9383PS时，应注意TDA9383PS的版本及与CH05T1601、CH05T1603的对应关系，并更改相应的外围元件；5．CH05T1606与CH05T1608可以互换，但OSD显示风格及EEPROM数据不同，代换时需征得用户同意。

CH05T1619可以代换CH05T1608，但EEPROM数据不同,总线数据中增加一调节项“PWL”,该数据设置为“14"，CH05T1619与CH05T1608OSD显示风格相同.7.CH05T1619可以代换CH05T1606，但EEPROM数据不同，总线数据中增加一调节项“PWL”，该数据设置为“14”，CH05T1619与CH05T1606OSD显示风格不同。
从普通彩电到高清彩电的维修摘自家维大众版2007.11～12 诸秀成一、高清彩电电路概述CRT高清彩电与普通彩电相比，从外观上仅多出了许多输入插口，其他并无二样。
对于普通彩电而言，仅有A V输入／输出和S端子输入插孔，而高清彩电除具有上述插孔外，还有YCbCr(隔行色差信号输入)、YPbPr(逐行色差信号输入)、VGA及DVD数码流输入等接口。
拆开后壳，从电路板上元器件分布看，除多出一块竖立的电路板外，其他同普通彩电并无多大差别，且可明确地判断出电源、行扫描、场扫描、伴音功放、视放等电路。
图1是长虹CHD29168彩电(CHD－2机芯)电路板实物图。
仔细观察后，你会发现多出的插口通过导线与这块竖立的板相连，看来这块板正是高清彩电区别于普通彩电的重要部件，这块板起什么作用呢?高清彩电采用60Hz(或75Hz)逐行扫描方式，以提高图像清晰度，这有别于普通彩电的50Hz隔行扫描方式。
由此可见，无论输入的是多少频率的隔行扫描信号，都将变成60Hz(或75Hz)的逐行扫描信号，而担当此任务的正是这块竖立的电路板。
根据该电路作用常称之为变频板或数字板，简称IPQ板。
提示：高清彩电与普通彩电相比，电路结构基本相同，但为了提高清晰度，采用了逐行扫描方式，故在视频信号处理电路中加入了数字变频电路，旨在将50Hz隔行扫描信号转换成60Hz(或75Hz)的逐行扫描信号。
由于高清彩电输入的信号种类较多，既有50Hz隔行扫描的TV全电视信号、A V视频信号或YCbCr信号，又有逐行扫描的YPbPr信号，还有由VGA接口输入的模拟R、G、B信号，所以数字板应设有相应电路分别针对各类信号的特点进行变换处理，既保证最终信号格式的统一，又保证行、场扫描同步进行，各类输入信号流程如图2所示。
从图2中不难看出，数字板的核心任务是数字变频及扫描格式变换。
提示：在高清彩电中，TV／A V信号、Y／C信号及Y、Cb、Cr信号均要通过数字变频处理，转换为逐行扫描的亮度、色度信号；VGA－R、VGA－G、VGA－B信号与YPbPr信号虽不进行隔行转逐行处理，但要进行格式识别同步信号分离与ADC转换等处理。
