Question about Akai LCT2715 27 in. LCD Television
TV was given to me dead. I removed and recapped the 200W power supply using good 105 degree C capacitors. Most of the old caps were shot. TV now works fine. Unfortunately, it has a loud buzzing that appears to be coming from one (maybe both) PQ3220-1000C transformers.
Would you have an idea of what other component(s) might still be defective? I see no other visible damage to the power supply.
Did you use the same as original replacement capacitors? I have repaired many of these power supplies for others and never had an issue. It is possible that the failing capacitors could have caused more damage to the power supply but I have never seen it in over 50 repaired AKAI power supplies. Also, make sure you replaced the capacitors with the proper polarity.
