Press any key or use the remote control box, the TV has no reflection, no display and black screen. The process of maintenance : Remove the plug of adapter output, measure adapter output voltage is +12V,the adapter works normally. check the connection with key board、remote control receiving board and mainboard. If they are ok, the problem must be MCU not work. First check supply power of U2 chip. Connect power supply, then measure the voltage of the 2、4 pin of U13 NTMS10P02 is 0.2V,and over-heat , the reason must be short circuit of power supply backend. You should remove the plug quickly, otherwise the chip must be bad. Use the multimeter to measure ，confirm it is short circuit to ground. The places which connect U2 with 3.3V voltage are so many, you should disconnect and measure it one by one. when you disconnect the C68, it is normal, So it is caused by C68 Short circuit to grounding. Example 2: No picture in VGA mode 2. Troubleshooting phenomenon: in TV/AV mode ,the image and sound is ok, PC (in VGA mode) is no picture, but have state icon. The process of maintenance: first check the signal source, signal socket、plug are ok or not. Because during switch the mode, the image display normally in non-PC mode ,it is proved that the backend image public processing channel is ok, namely U3 MST518 and backend image signal processing circuit work normally. In PC mode, measure the arbitrary pin of 4,7,12 pin , image data port of U6 P15V330A by oscillograph, there are no waveform, change U6P15V330A and the Troubleshooting phenomenon disappear. Example 3: no picture in VGA mode and the “signal beyond boundary” is appeared on screen. 3. Troubleshooting phenomenon: no picture in VGA mode and the “signal beyond bound” is appeared on screen. in TV/AV mode, image、sound is ok. The process of maintenance: first check the signal output from the signal source is standard or not, or beyond the resolution which is supported by TFT panel. except of the two cases, the phenomenon comes from the TFT display. Under general circumstance it is caused by the abnormal of the horizon sync impulse ,vertical sync impulse of VGA signal. Inspect the 38th、39th pin of U3 by oscillograph, find the magnitude of horizon sync impulse is below th the normal, measure the waveform of 13 pin of VGA J1 ,if it is ok, so maybe the value of resistor R23 will be largen, measure the resistance of R23 is 10K Ω,but the rating resistance is 1KΩ, so it is obvious that the magnitude of horizon sync. impulse is attenuated too much caused by value of couple resistance R23 become large. So the pixel clock inside of the MST518 can not vibrate, result in the A/D converter of MST518 internal can not work normally . So appear no picture in VGA mode and “signal beyond boundary” on TFT screen. Example 4: Can control TV by remote control, but can not control TV by key board 4. Troubleshooting phenomenon: image、sound is ok under any source, use remote control to operate each function is ok, but can not control by using the key board, failure completely. The process of maintenance: first check the socket of J6 on mainboard ,the solder joint and touch of connector are ok or not. if it is ok, check the key board ,measure each resistance, find R1 open circuit, change it . Example 5: the image is ok after turn on the TV, but left speaker has no sound output 5. Troubleshooting phenomenon: the image is normal in TV mode, but the left speaker has no sound output, using remote control to operate ,each function is ok. use AV、PC audio input ,is still no sound output. th The process of maintenance: measure the waveform from 60 pin of UOC by oscillograph, according to signal flowchat, measure R227、 R157、U8、C130 one by one, and observe the waveform is ok or not, find the back end of C130 have not waveform, change C130 and troubleshooting disappear .
