I had my MD30112 PSU blow up recently. I shipped it to Ohm Supplies and they fixed it and shipped it back to me for just over £50. I think they sell a repair kit too.

My 32 inch LG TV has a horizontal line down the middle and one side is very slightly darker

Most likely problem is the display panel. You might check the connectors between the T-con & panel looking for corrosion or signs of arcing. If you see corrosion or arcing signs, clean those areas & see if the picture is now OK. Otherwise you need the Panel & it is not cost effective.

Surge outage tv not coming on

Quite possibly just blew TV fuse, but may have more damage, usually to the power supply circuit.
Unplug TV & remove back & do a visual inspection of all PCBs & wiring. your looking for physical damage, traces of arcing, parts blown apart or damaged/discolored.

Hi, I have a 32"

Your description roughly fits what is called a 'cold solder joint.' The crackling you hear may be caused by arcing around a defective solder joint and these can start a fire by igniting the epoxy of a circuit board; it's not wise to count on the arcing to stop by itself although once the joint has expanded slightly it may restore contact for a while. This type of failure is normally related to a junction carrying a relatively heavy current load, hence the arcing. I would not use the set until you have made a thorough visual inspection of the boards with particular attention to any separate power supply board. This kind of failure is normally visible under magnification and you may find a crack around a heavier pin. Look for charred areas around the failed joint and if you find one, it would be safer to replace the board but it is also possible to scrap away the burned area and restore connection with a wire bridge; the charred area can be conductive and still cause a fire.

Tv will not turn on

Check the PSU/ power supply unit not the cord. The cord is never the issue in this complex problem. You may have a blown fuse in the PSU if its a IC intergrated circuit then it needs to be looked at by a qualified Tech.. We only can help you without looking at it, hope this helps

No pricture on 32" Hannspree HDTV. Worked fine night before and now it comes on, but no picture.

If the TV still switches on, and you get sound, then it could be 1 of 2 things.

The PSU, less likely.
The Inverter, more likely.

It is difficult to determine which is faulty without some test equipment etc.

I hope that helps.

POwer Supply blown

just get the specs for that PSU. Look for the output voltage and current and buy one of the same specs. The voltage should be the same but the current may be the same or higher but not lower.
