Philips 32PF5321D/37B Powers off and on Intermitently

Recently our LCD Flat Panel started cycling the power on and off on its own. When the set is first turned on, it takes longer for this problem to occur... roughly 20-30 min. But once it turns itself off and then back on, it will continue in 2-3 min. intervals. Eventually it cycles off, the green ''power LED'' on the front still shows like the set is on, it recieves signals from the remote because it blinks every time you hit a button yet nothing happens. You have to unplug the TV from the AC Outlet and plug it back in to reset it. The twist is, if you listen to the digital music channels from the service provider, and there is no picture, the TV set performs like it should. I don't know if this is temp. related, and when the picture is being displayed its working harder and heating the components causing something to open. I've got about 6 years exp. with electronics but absolutely zero exp. with TV's. Has anyone seen this problem, or know anything about it. I've been told it is chronic with these Philips models. I thought I had escaped the disease until now. I'm sure other people have encountered this problem. I'd like to know what it was and approx. what it would cost to fix it. Thanks

It sounds like the horizontal (H stop) and vertical (V stop) has gone bad. Check Cap 515 and 516. IC1509, Q1505 and the jungle IC, IC206. You can also bring up these fault codes on-screen to see a list of the problem numbers with the abbreviation of the problem and the number of times this problem has occurred. This is slightly different than entering the service mode. To see the diagnostic screen, press the following buttons: Display, Channel, 5, volume Minus, ( not plus ) then Power. This brings up a screen with a list of the problems and number of times they have occurred. Each of the problems named, are abbreviated as, "OCP", "OVP", "V STOP", ETC.

How many times does the POWER led blink per sec? (dont worry about the OPC)

2x = power supply (not as expensive to fix)
3x = Main board (expensive to fix)

The tv keeps turning off by istself


You may want to try upgrading the firmware. My Philips plasma set did the same thing and a firmware upgrade fixed it. The procedure is simple enough, just copy some files onto a USB drive and let the TV update itself. The release notes give detailed instructions. I couldn't find your exact model number on the Philips site, you'll want to get the correct firmware for your set.

Philips 42PF7220A/37B won't turn on at all. No green or red lights come on. This happened after we had a storm and the electric just went out. Any ideas?


Most likely it's a power supply board related issue. It maybe something simple like a blown fuse on the board. The fuse replaceable. Radio Shack or Electronic supply place will carry replacement fuses.
The other possibility is the power supply board itself is damaged. It maybe a bad capacitor or a transformer on the board. Replacement boards can be found on the internet. A good place the start is Shopjimmy.com.
