If your LG LCD TV has no power and the LED indicator is off, try the following: check for a short in the main B/D, check the 15V or 5V, change the Lips of Lips Fail, check the output of Change Q1100, check the output of Change IC1107, IC1104 IC1107, IC104, check the LED Assy and change the LED Assy, check P1100, P210 Connector.
What to do if my LG RZ-15LA70 has no raster?
If your LG LCD TV shows no raster, try the following steps: check the LED status, check and change L900, L901, L902, L903, check the input and change IC901, change the inverter and check the inverter connector or inverter, change the panel link and check the panel link cable or module, check the input source cable and jack and change module.
Why is there no raster on component signal on my LG RZ-15LA70?
If your LG LCD TV has no raster on component signal, check the signal of JA1200 or L1200, L1202, L1203. Try re-soldering or checking the input/output and change the defect part, output of IC1. Also, try re-soldering or checking the input/output of IC800, IC851. Additionally, re-solder or check the input/output and change the defect part, output of IC901. Finally, check the input source cable and jack.
What to do if there is no raster on AV signal on my LG LCD TV?
If there is no raster on AV Signal or TV(RF) signal (Video, S-Video) on your LG LCD TV, check the 5V, 33V of TU1000. Also, check the signal of and change L1209, L1210, L1212. Re-solder or check the input/output and change the defect part of IC1. Check the input/output and re-solder of IC800, IC851. Re-solder or check the input/output and change the defect part of IC901. Finally, check the input source cable and jack.
Why is there no sound on my LG RZ-15LA70 LCD TV?
If your LG LCD TV has no sound, you can try the following: check the source input, re-solder or check the input/output and change the defect part of IC1, check the input/output and re-solder of IC100, IC101, check the speaker and change the speaker, check the speaker wire.
