Free service manuals? for 37lg3000 LCD TV
Hi everyone.
Anyone know where I can get a free service manual for the LG 37LG3000 LCD TV? When I power it up, the red LED brightens 3 times at 1 sec intervals before finally going blue, with no picture or sound. Thanks |

Thanks Not familiar specifically with this model, but have you checked that the 24v rail establishes ? Many LCD power supplies produce one that feeds both the LCD panel backlight inverter, as well as the sound output stages. Is it by any chance a Vestel chassis using a 17PW xx series power supply ?

put finger to keyboard and composed: Anyone know where I can get a free service manual for the LG 37LG3000 LCD TV? FWIW, here are service manuals for LG LCD TVs made for the Australian market: http://www.jordansmanuals.com/Defaul...LCD&Model=32LG Maybe there is a similar chassis? - Franc Zabkar -- Please remove one 'i' from my address when replying by email. |

Arfa How do I find out what type of Chassis it is? The main PCB HAS lg500/3000 screen printed which gives the impression it's an LG chassis? |
