How to fix a flat screen TV? Here's an example of one we worked on.....

How to fix a Dead 37" LCD TV Scott / LG / AKAI Model # LCT37SHA
TV also sold by RadioShack. Died in less than 13 months!

No Red light - No Power - Power Supply Dead - Power Supply Fried. Part # MLT386X

Started fixing the Power supply -

Dead (shorted) FET Part # 20N60 at position QA1 cost about $3
Don't forget the little gray ferrite-type bead on the center leg and use some thermal heat paste (the white stuff)

Shorted 1N5406 Diode at position DA2 ($0.19) and fried parallel capacitor CK23 underneath - Make sure you clean the cap and residue off the board - This cap arcing may have been the root cause of the FET failure, replaced with 1000pF ceramic *there are several others around this area.

Others have had to replace the 1000uF and 470uF caps in the secondary part of the supply - mine were OK

Open 5A Fuse of course.

Parts all obtained from Total Parts cost about $5

UPDATE 9/28/09

Success! Replaced 5A 250V Slowblow Pigtail Fuse, FET (QA1), Diode (DA2), Capacitor 1000pF (CK23) under DA2 diode,
Added new heat compound where it had dried up. I am considering adding fan above PSU to avoid this problem in the future.
The heat problem with this unit made me decide to add some fans - I just don't want to do this fix again.
