Coppell TV Repair offers you a repair kit for a known failure in the LG 47LC7DF LCD TV power supply board.
Like with all our repair kits, we can't guarantee that it is all that the board needs (or that it needs it at all), but a careful reaad of the below technical information may help isolate some common confusions.
If you are not certain in your ability to troubleshoot and correct the problem please consider sending the board to us or elsewhere for repair.
Coppell TV Repair will not be responsible for unsuccessful repair attempts with this kit.
A completely dead TV - no LED standby indication, no response to commands, nothing.
This alone can be caused by multiple reasons, so here are a few more technical (and more reliable) indications that this repair kit will be of use:
- Open main fuse F700 on the power supply board (continuity check fails)
- Open or shorted transistors Q608 or Q707 (short or low resistance in both directions between any pair of legs)
- Open or shorted (usually shorted) diode D703
F700, D703, Q607, Q707 and possibly others as we gain more experience and information about components likely to have been knocked in the failure process.
Easy to intermediate. Requires soldering, but mostly any soldering equipment will do.
Access to the power supply board requires one regular Philips screwdriver.
SHIPPING AND HANDLING
The free shipping and handling included in the price uses USPS First Class package within USA and possibly Canada.
