Check the solder only around the flyback area because that could make a set work off and on

  • It improves accuracy in the soldering process as temperature can be easily regulated to maintain a healthy flow of the solder.
  • It is easily accessible as the Indian market offers very reasonable prices and quick delivery for any soldering products that need to be purchased.

When i try to turn on the tv it wont come on and then if i leave it a while it will turn on and work fine so i took it off the wall and gave it a clean and now it wont come on at all it is a LG plasma tv

Sounds like either a loose connection suspected from the fault worsening when you moved it, or a dry solder joint on one of the pcbs. It could also be a dry capacitor on the power supply board shown by bulging tops on the capacitor. It could be that when mounted on the wall, the tv was located near a source of heat and this heat helped the low value capacitors to warm up and work. Either way it will be one of these 3 possible solutions.

My paeveybandit 112 is buzing when i turn it up

Check the power supply area for bad connections especially near the large capacitors. If one or more of those are disconnected, the DC voltage will have some noisy AC on it that will sound like a buzz.

Keep us posted.

Bad solder connections on the vertical ic

Hi,

Cold solder is normally fix with re-application of heat using a soldering iron. This is a fairly straight forward job and should not be that difficult. Probably what would take more time is opening the back cover and exposing the solder side of the PCB. Most TV PCBs are slide in/out (it may held in place by screws or retaining clips or side locks. Additionally, some of the wires/connectors may restrict movement and therefore must be disconnected temporarily).

Good luck and kind regards.
