Question about Philips 26MF231D 26 in. LCD Television

3 Answers

TV Powers off after 30-45 mins

I have this TV in the 32 inch model and after 30 - 45 minutes the TV screen will make a loud static noise then the screen will turn black with some white on it and turn off. The TV will then reset itself and then do it again with in 60 seconds. Is the TV over heating? I just replaced the power supply board less then 2 months ago. Any help would be great. Thank you - Jeff

I had the same problem with my 1 year old 26" TV. I called Magnavox customer service, and they had me upload a new software driver to the TV - which didn't solve the problem. Then they suggested that I call the local Authorized Service Center - and they estimated that it would cost $200+ to fix the problem. But then I found the "remove the back solution" listed here - and it worked!
Thanks, you saved me at least $200.

    Hi all i found the problem i have the same lcd model #26mf231/37 Mainboard #313815866861 6182.2 , 6281.3 ,6285.4 All apllies Im a technician since 1990 and here is what i discovered. I opened the back cover and removed the metal casing i cutoff a rectangular box from the metal casing to expose most of the power supply and i also cut the same square box from the cover backside. bought a metal mesh so that the power supply can breath. Next i wanted to make sure my main board was good so here is what i did. I pluged in my soldering iron 30 watts then located a crystal board location 1H00 and i applied heat to it while the tv was on and sure enought it turned off that's where the problem is. Remove the main board and add alittle bit of new solder and walla. Let me explain the problem: The 1H00 is a crystal safety feature when it gets hot the solder around it contract therefore it looses connection is common is lcd/plasma T.V's heat is Evil in any component. Anyway once you have acomplish all of the above you should be good to go. Please email me and let me know how you made out with the T.V.
    Remember cold solder is the killer for all electronics

All you need to do is remove the back cover, then remove the metal cover that covered the power supply. Watch tv w/o cover, it won't shut down again. Try it and post here if it works.
