I bout a non working Phillips LCD. At first it had no picture at all. I first replaced the 4 Caps recommended in other threads. After that when I turned the power on it would just click every half second. I then also replace the two Diode juts below one of the transformers. It now turns on but at random it will flicker. And it also appears to segment the screen in 1/4's starting from the top down. Then at times the picture is perfect. Any suggestions?

Re: Phillips 47PFL5422D Screen flicker
This may be a tab bond problem, but can you check from the rear of the set to see if the backlight is staying on or if it is going off? You should be able to see the backlight through the holes in the panel.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Phillips 47PFL5422D Screen flicker
I should clarify, When I say flicker it actually never goes dark. I also noticed if I tap the frame it does seem to affect the flickering. I also now notice on darker movies/show there appears to be a slightly darker area of the screen.Comment

Re: Phillips 47PFL5422D Screen flicker
You have a bad tab bond then.
It is repairable, but difficult.
This is a different fault, but the root cause is the same:

Re: Phillips 47PFL5422D Screen flicker
Did exactly as the video demonstrated and found when I would push on one of the tabs the screen would flicker. Used some rubber under the tab ribbon and now it seems to be working fine. Thank You!!Comment

Re: Phillips 47PFL5422D Screen flicker
Glad to hear it's fixed. It is often recommended to put shims under each side. If the right tab failed, then apply a shim to the left tab too.
Also, can you tell us who made the LCD panel in this TV? LG Display/LG Philips? Or another manufacturer?Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

It's written on the panel sticker. A picture of the chassis and I will highlight where it is.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Phillips 47PFL5422D Screen flicker
I wish people posting would finish the discussion before they disappear with out a word, but they get what they come for and go.
Anyways that video is awesome, I did NOT know you can do that and I have tossed maybe 10 of those Sanyo TVs. I still have a few I can test it on.
norcal715 sure does have some good YouTube videos.
I am working on a Philips 47PFL5422D/37 but my power board is bad so I will continue on the correct thread for this issue.Comment
