LA76810 fault info table

LA76810 fault info table LA76810 fault info table Foot fault 1C122 breakdown caused by silent figure 2C121 breakdown caused by silent figure 3C120 breakdown caused by a silent picture, blue screen normal, open circuit appears in the boot, full screen big snowflakes, deterioration, and then no sound, blue screen 4C119 breakdown search station did not respond, R119 open circuit will cause no picture silent search Taiwan, no response 5Z101 does not cause the image to have snowflake, no color, heavy image serious 6Z101 does not cause the image to have snowflake, no color, heavy image serious 7 8L102 open circuit caused no picture silent search Taiwan, no image appears; C115, C116 leakage, breakdown are caused by no picture silent, search platform no reaction 9R120 open circuit causes no sound, the image is normal, C117 breakdown, metamorphism all cause no sound, image 10C118 metamorphic breakdown, the image appears in the boot, then a clear, and after a while there is no, as if in fine-tuning The open circuit of 11R241 and R242 causes black frequency, noiseless picture and high acceleration voltage The 12 side compression, retrace line, have blue, sometimes also caused no boot 13C408 failure, appear on the image of some black spots, about each have a black spot, VD402 breakdown caused black screen, there is sound 14, in the case of signals, such as voltage is not normal, generally due to bad internal, need to replace the IC 15, in the case of signals, such as voltage is not normal, generally due to bad internal, need to replace the IC 16, in the case of signals, such as voltage is not normal, generally due to bad internal, need to replace the IC 17 no black level input causes point screen, but there is a sound 18R243 open circuit will cause no picture, sound, black screen; C245, C244 leakage metamorphism will lead to black screen 19RGB output, if there is a signal, the three voltage is not normal, all need to exchange IC 20RGB output, if there is a signal, the three voltage is not normal, all need to exchange IC 21GB output, if there is a signal, the three voltage is not normal, all need to exchange I 22 normal 0.42V, voltage is too low, will cause the search station does not exist, you need to change LA76810 or CPU 23 No 0.65V output causes horizontal light to be replaced by IC 24C402 and C403 breakdown can cause horizontal bright line and often linear negative 25R400 open circuit caused no picture silent, not boot 26R402 open circuit, C407 failure causes top distortion; C407 breakdown occurs out of sync 27R409 open circuit, no picture black screen, sound 28VD411 breakdown will also cause no blue screen, image folding around the phenomenon of no sound; R413, R412 open circuit, there is no blue screen, there is noise, there is a signal when there is sound 29R273 open circuit without picture silence 30 unused 31R27 open circuit, C278 leakage, the image is gray, dull color, chroma added to the highest 32C273 breakdown, leakage occurs, the image is green blue 33 34C275 failure, the image is green blue, no red 35C274 damage has little effect Bad 36C210 will make the color strong and weak 37R268 damage has little effect 38C209 effect causes no color, and G201 bad also causes no color 39C207 breakdown occurs silent, noise, no sound 40R260 open causes no AV image 41 42C211 failure causes no AV signal to be entered 43R270 open circuit, horizontal bright line, have "rustle" sound 44C204 leakage breakdown caused by no picture, sound, black screen, failure, no image, can not find Taiwan 45C203 invalid, there is a picture sound, but the image in the middle of a width of about 10cm transparent bright band 46R201 open, no map, silent screen; R202 open image, lower noise, gray image 47C137 failure causes trailing edges in white, for a while, silent, single screen with snow like dots 48T101 failure will result in search platform not stored in Taiwan, search less than Taiwan 49T101 can't be adjusted randomly 50C139 breakdown no picture silent; R127 open circuit also cause no picture silent; C139 failure will also have no sound 51R814 open circuit causes AV to have no sound 52R112, C125, C126, any one failure, there are plans silent, single "rustling" sound
