Dry joints ???
Fuse blowing on these is due to a transistor going open circuit, blows/trips main fuse in plug/fuseboard and pcb psu component.
Part number HA160T1A1 is no longer avaliable to replace the board after only 14 months service the lesson is you get what you pay for, go for more reputable manufactuer :(
Bad company with cheap and nasty products.

Hello, This might be a board with a loose connection or a faulty capacitor on the power board or one of the immediate circuits attached to the power supply board. I would suggest that you have this serviced by a qualified TV Technician. However if you wish to do this yourself, you need the following equipment: 1) Multimeter (to measure the voltages; AC and DC on the various test points on the boards) 2) Oscilloscope (to measure the startup and shutdown circuit ramp voltages) 3) Isolation Transformer (to isolate the Tv from the AC circuit that the test equipment is on) 4) Service manual or schematic diagram (to show where the test points are and what signals and voltages to expect) 5) Signal generator (to generate reference signals for servicing the TV) Now if you know how to use these pieces of equipment your are ready to start, if not again I would advise you to have the set checked by a qualified TV repair technician. I hope this helps Thank you, Shuttle83 http://www.electron-age-technologies-llc.com

I just fixed this very same problem. It is the capacitors are the problem. However, I think that if you have some minimal skills with soldering, you can fix this yourself. You just need to take out the system board, then the power supply parts are on the top right. The bad capacitor(s) will be bulging at the top and possibly have some brown stuff coming out. The ones that go bad are 1000microfarad, 10V, however you can replace them with higher voltage. I got 35V caps from radio shack for 1.59 each. You just need to solder out the bad ones and then put the new ones in and solder. Remember that the negative end goes on the side with the bold black part of the circle on the system board. Then just cut off the extra ends of the capacitors. If you are capable of doing this yourself, you will spend at most 6 dollars instead of however much a technician costs.

About $100 if excellent condition,very good condition about $75-80.Not more than that.

check power supply capacitors..i repair these every day and the power supply is prone to faulty capacitors..the capacitors should have flat tops and if they are bulging or leaking brown fluid, replace
