SOURCE: samsung plasma ppm42s3 , picture wobbling,sometimes screen goes blank

Hello arunaik_6,

This looks as if a component has become thermally sensitive. The best way to find this is to use component cooling spray. It looks as if the problem is localized to the tuner section. Take the back off of the TV and turn the TV on, wait until the problem occurs and lightly spray the tuner section with the component cooling spray watch for any reaction, then if this does not work spray the Microprocessor and the LVDS section and watch for a reaction. The set should go back to normal when it does that section is the problem, try to localize the problem to one component. Then replace that component.

I hope this helps,

Thank you,

Hello,

Your power supply board is not yet dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com and Ebay.com to buy a whole refurbish power supply board for the replacement.


take care.

Frigidaire dryer hums when button is pushed in but won't start


ok can u turn the tumbler freely,
if no well there is something stuck in you blower like a sock or something
if the tumbler turns freely
keep the door open and hold the door switch
try pushing the start button
and tuning the tumbler, yes all three at the same time lol you may need a hand
try tuning the tumbler when you hear a hum
if it takes off bad news your start winding on the motor is bad or the capacitor depending on your model
if it does not turn, but the hum continues longer than 1-2 minutes it could be just a belt

Tv comes on for a few minutes then goes off


If you take off the front bottom panel of the tv wich is easy. Then you will see 6 tuning knobs at the bottom middle of the tv .the top 6 control contrast for the lights dont mess with those. the bottom 3 are the power to each light.red is bottom left if your screen went blue it makes sense that the red is starting to go but if you turn down the power to it left 1/8 turn it should fix it for awhile .Its easy.

LCD screen looks like bad TV reception


if the display returns to normal when you press the bezel at on end means there is a bad connection to the inverter behind the bezel itself or the inverter is ready to give up the ghost.
you can attempt to dismantlethe laptop and remone the lid or in some cases just unscrew the bezel and remove the plastic cover, the inverter is at the bottom of the display you can't miss it

hope this helps

TV turns on at odd hours by itself


Hi, I had the "Ghost In The Machine". I tried out what I descibed in my original posting.
#1. I unplugged The Set.
#2. I pushed in and held in the power button in for about 5 minutes before bedtime. ( The PC trick I learned) I gave it 5 minutes because a tv set has much more power inside it.
#3. I again pushed in and held the power button in again for 3 minutes the next morning.
#4. I plugged the tv in again. The red standby light was lit. The set did not immeadiatly come on when I tried to power it up.
#5. 5 Minutes later I returned and hit the power button on the remote and it came on like nothing ever was wrong.
#6. It has been fine now for 3 days!!! Powers up when commanded and shuts down like normal. It has yet to come back on or act up as it was doing.
I will keep a watch on it and if it starts up acting again I will repost. I hope this information will be of use to anyone who experienced the same problem. It didn't cost a dime, just some patience. Thanks for a forum that people can exchange information and save trouble and money unless all options are exhausted. Bill

Your model has a maximum resolution of 720p. What you might want to do is make sure that both your cable/sat box and game stations are outputting at no more than 720 resolution. It's easy to assume that all HDTVs may accept a higher signal, and while they might, some of the scene changes or handshakes may make that operation cause the symptoms you describe.
