Question about Samsung PS42P2S 42 in. Plasma Television

2 Answers

Power swith ic went bang!

Whilst watching my ps-42p2st samsung plasma 42" tv the other day i noticed smoke coming from the back of the unit. As i scrambled for the remote a loud bang & flash occurred & the screen went blank.

I opened it up & noticed the internal fuse near the power supply connection had blown (not the one on the psu board). I also noticed that a fairchild power switch (1m0880) had blown apart on the power supply board & there was evidence of smoke residue near this. There are a couple more of these ic`s on anoher part of this board but this one was mounted with another smaller ic to a heatsink. I also noticed that a capacitor (0.022 uf ) near three transformers had been getting hot as it appeared to be split & possibly spitting a bit.

I replaced the fuse & the superseeded 1m0880 with a fs7m0880tu & the capacitor was also replaced. i switched the unit back on but no joy! the light comes on & the relay can be heard to operate but there is no picture or menu or anything. Can anyone suggest what my next step or options might be. I`m a bit reluctant to purchase a new psu board only for it not to be the problem.

many thanks in advance.

Unfortunately these boards are now obsolete, it may have damaged the bridge rectifier

I have a 42" LG


Hi,
It can't be fix by replacing the fuse alone because the IC's and other parts are already faulty. You need to replaced the entire Y-sustain board. Try this LINK or obtain it from your local LG Service Centers.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

Samsung PS-42S5H


Since you smell it above one side of the panel I will guess the right side (from the front). This is where the Y Sustain board is located, it has large heatsinks over the drive ic's to dissapate heat. If the ic's are bad this is more than likely the smell. This board controls the scan of the picture and drives the plasma panel. I would definatly have a technician look at the unit, these are normaly econimical to repair.

Ps-42p2st samsung plasma 42" does not power on!!


A computer cord is the same as the original. Go to any Radio Shack or TV shop and ask them to check the fuse to see if it is good or bad. If it is good, then suspect moving damage. If the fuse is bad, the person checking the fuse should be able to suggest a proper replacement. After replacing the fuse ( only if it checked bad), re apply power and hope the set comes on. If the fuse blows a second time, you need to call a technician. One other thing, some sets have a vacation switch that can accidentally get pushed during a move. Consult with the owners manual to verify if your set has one.

No indication of power what so ever


Yes, a computer power cord is the same.
Without physical sign of damage, it will be hard to induce the movers to cover the problem. You will need to take it into a reputable TV shop and get their evaluation that whatever is wrong is due to the move. Its odd that it failed while off, however of course all these new TVs are not near as reliable as the old ones. Might just be a dislodged connector inside.
Hope Ya Fix It!
