LG lcd service manual- part number information?
« on: August 27, 2012,05:03:16 »
All the LG lcd manuals I have downloaded don't include part numbers.

Does anyone know hoe to get access to model number internal part numbers?

Has anyone else had a similar problem?

Only available to account holders to prevent the general public gaining access to the already tight budget that we work to.

hi tony, sorry to be cheeky you wouldn't happen to have a service manual for lg flatron w2042s-sf knocking about. the power supply is aip-0172 i found 3 capacitors bulged 470mf 35v replaced them, all i get is a blue light that's it i've checked diodes and replaced the rest of the capacitors my thinking is transformer or disc capacitors, thanks for your time

regards

  hi,usually the unfiltered voltages on this psu lead to the breakdown of u303,u304(APM4048,complementary MOSFET's)so +22V results shorted to gnd;try to replace them.
