    I am getting a split second of sound, no picture. I hear 3 clicks then it shut itself off. I replaced the fuse and checked the caps but dont see any bulging there. Could they go bad withoout any physical signs? Any other suggestions would be great.

SOURCE: replacing power supply HP M8120N

Here is the link for the upgrade and service guide.

This one is just as easy as 1) removing the side panel; 2) Remove the four screws that hold the power supply into position; 3) Remove the power supply cables from the motherboard (NOTE: If the media bay reader is in the way, you remove the front bezel by pressing the release tabs on the bezel and it will swing open. Remove the one screw securing the bay in position, then slide it forward so you can reach the power cable to the motherboard.); 4) Remove the power supply cables from the hard drives, cd rom drives, and other peripherals inside the PC. 5) Remove power supply...sometimes there is a button to push and it will slide out, sometimes not. 6) Replace power supply, then reverse procedures.

Thanks and please take a moment to rate as fixya.

SOURCE: need to replace a Lite-on power supply

No really a solution. Could do we someone just saying where a Liteon PS-5221-06 power supply could be bought from. That would be the actual answer to the question!

My Samsung TV model number LN-T4032H turns on fot a while then shuts off by its self but sound stays on, i dont know what's wrong with it, anyone know why?

The power supply in this TV uses poor quality electrolytic capacitors which dry out over time and become faulty. They need to be replaced by someone who knows how to repair circuit boards.

My samsung le37r88bd suddenly went dark and now needs the brightness turned up full also any text stays superimposed in the background for a while

sounds like text is staying on screen because you have brightness turned up too much

the reason it is dark is probably because backlight is bad - backlight is flourescent bulb and if you have ever seen a flourescent bulb you know how it gets dark from edges almost as soon as you start using it

you might be able to replace bulb yourself if you are handy or bring in for service

there is a chance (possibly a good chance) that the power supply for the backlight is bad also - you might want to consider if a repair is worth it considering how cheap they sell these things now

let me know if i could be of more help

good luck!

Relief valve on my water heater is dripping.Can I fix this?

There are two solutions:

1) Replace TP valve with same temperature/pressure as existing TP valve.
Buy the TP valve at hardware store or home center or plumbing supply.
Turn off water heater so water cools.
Hot water inside a tank is explosive ... so open the TP valve and test water temperature.
If TP is on top of tank, you don't need to drain much water before unscrewing
If TP is on side of tank, use the TP valve to drain water -or- use the drain valve
Unscrew TP to remove.
Put teflon tape on new valve threads so it will seal against leak.

2) If the new TP replacement starts doing the same thing, there may be a thermostat problem -or- thermostat is set too high.
If you keep the water temperature set high, you can add expansion tank to incoming cold water line.
Home Depot sells expansion tanks. Plumbing supply carries them,
The tank for residential water heaters is about same diameter as a football and it goes on cold water line.

I have a Samsung TXN3075, makes great video from laptop or cable input...for about 5 minutes, then its good audio, black video, until it cools down then it will work a bit. Could someone give me a bit of...

The screen is overheating, due to either a malfunction or poor engineering/assembly. It shuts itself off (as it's the HOTTEST part of any TV) to keep itself from basically bursting into flames.
Contact the manufacturer and have their tech support guys help you out with it. They may have other similar cases and perhaps even have some sort of warranty extension/free replacement based upon that specific problem.

Bad picture

Hi Dan,
It sounds as if you have a bad filter capacitor in your power supply. Check the main filter caps rated at 150 volts and above. It's likely one is leaking and need immediate attention. I hope this helped. Good Luck
