    same problem....started 2 weeks ago. Today is April 16, 2009

    All of the sudden my HPT4254 samsung plasma will shut off and then on, like i set it to sleep mode, but i didnt even touch slep mode, it has been doing it quite often.



    What is happeneing is that the capasitors are swelling because i have been running it alot, day and night. if a plasma runs all the tim, it gets hot and stays hot, so the capasitors work hard and it swells and bulges.



    Remember Folks, you have a 2 year in home warrenty with samsung plasma televisions. so i am just going to honer the warrenty and save up for another television. i think i will go with a Sony LCD. The Bravia 2 engin is Superb in fast movements. like a plasma, or a L.E.D, L.C.D.



    As for plasma, i dont recomend getting one if you are going to be running it almost 24 hours a day 7 days a week



    I hope this has been helpful

Hi Rickpo:
After installing the $11 kit and the additional $13 kit recommended by (http://preher-tv.blogspot.com/2010/01/samsung-hpt4254-no-power-repaired.html) mostly surface mount diodes (also available on Ebay), the Samsung HP-T4254 came back on, but would only play for 4 minutes. I found DX801 flowing both directions, replaced it with a diode from Fry's. Works great, $26 total repair costs :-)

SOURCE: HP-T4254 samsung TV turns itself off and on

Try this step before purchasing power supply. I have serviced this tv before. Lay it flat plug it in and it should turn on,but once you sit it up straight it will turn off. I think there are faulty fairchild mosfet transistors or a firmware issue. I put a 1 inch thick book under the stand so it tilts up or down. I have not had a call from any customer since.

SOURCE: can't get my samsung hp-t4254 42" plasma tv to

make shure that the computer is set up to display on the screen. To check and see right click on your desktop, click on the option that says screen resolution, and then change your settings from their. The tv will not register that you have a computer plugged into it if the computer is not sending the tv a signal.

I have a hp t 4254. it randomly turns itself off


There can be several causes for this, few of which you can do anything about. However, a few things to try:

1) Replace the batteries on your remote control.
2) Try resetting the logic functions on your tv by unplugging it for a minute, then plugging it back in.
3) Try covering up the infra-red receptor on the front of your TV to see if you're getting unwanted signals from the receptor. taping a piece of foil over that area is perfect. If it doesn't stop after doing these two things you'll probably need to take it to a shop.
4) If this does stop it, then look for unexpected signal sources. Have you added a remote control extender? Added a new device to your audio-video system? Changed to a new remote?

I hope this helps. Joe
