I have a Philips 42pfl3704d f7 and get sound but no picture. In checking online, a few forums are saying in need to replace the inverter board(s), as when shining a flashlight on the screen, I can faintly see the Philips name. Any idea if there's a video out there that can guide me through this repair/replacement?
Model: 42pfl3704d f7
Researching similar problems online, and removing the rear cover. That's all I got. Help a girl out, please.
Hello WelcomeThanks for using JustAnswerIf you could just answer the below info requests please this will help me a lot thanks!If you press the menu button of the sets own remote control does this appea or not please?Anthony
Not sure. I was able to see the Philips name faintly on the screen when shining the flashlight on it, but I didn't check to see if the menu came up when using the remote.
I would try it now, but I removed the back and it's opened up on my bed.
HiI seeIts very likely the backlight is out and this is controlled by the invertors that is the two boards running down either side of the set, now it doesnt necessarily mean these are faulty check 1 is the voltage usually 27voltsdc is present from the powerboard, the invertors themselves are then examined and replaced, its a simple execise to do that if the invertors are not hidden under the chassis, if you take a photo of the set with the back off and upload it using the paper clip on your toolbar I will tell you what to do and if necessary advise where to obtain the invertors fromLet me knowAnthony

HiOK I can see the one invertor on the right with the black insulator, their may be another though hidden under the metal I Will check this out just reply with OK and give me 15 minsAnthony
HiThis set uses an invertor powerboard arrangement, I am just tracing the most likely suspect without getting involved with voltage measurements, so please call back in couple hoursAnthony
HiThis set has a powerinvertor and invertor itself so the problem could be either or you can get pulled boards for this here, the powerinvertor is on the left of the AV input circuit board (the one with the RCA sockets)and the invertor proper is on the right, you can get both boards herehttp://www.shopjimmy.com/catalogsearch/result/?q=42pfl3704d+f7If you need any info on getting the boards out let me know but it will mean unscrewing andtaking off some covers to get at the right invertor, the powerinvertor is easyAnthony
