I have a DP46848 LCD HD TV, over a year old. The picture appears to be made up of several individual panels, maybe 12 or 16. Anyway, after it has been on for 5 or 10 minutes, parts of the picture get darker. No gone, can still see it, but very dark. Seems to be the bottem 2/3 or 3/4 of the screen and only the left 2/3 most of the time. This comes and goes for maybe 1 or 2 minutes, then it is OK from then on. It will occasionally do this again later, again for a minute or 2, but normally just the

When I turn on the set, the right half of the screen is distorted. It flickers, different colors move from center to far right of screen, double images that appear as negitives and sometimes that half of the screen is very dark. Sometimes it will clear up for a second or two then go back to the problem. When the problem first started, it only lasted for approx 10-15 minutes then the picture was great. Now it takes 1-2 hours for it to clear up. Once it clears, I get a great picture. The lef

I have a RCA L26WD26D Flat Screen TV. When you turn it on it will say "please wait". This lasts for 30 seconds or so. Then that goes off and the screen turns black with some sections turning white. It will vary the back and white and will stay like this for maybe 20 minutes. Then it will start showing vertical colored lines. They will change also and eventually turn back to black and white. After leaving the TV on for about 5 or 6 hours, the picture finally shows up and looks fine. So now I'm af

When first powered on the picture is very dark, returns to normal for 30-40 minutes and then has horizontal bars scrolling through the screen.
Your problem will be in the power supply of this TV. It will be the board that has the flyback transformer. You will have to pull this board out and find the vertical IC. I think it will be of the LA78XX series. You will have to resolder this IC, and ...

The pop you have heard from has come from the buffer boards. When one buffer boards goes back, the other goes out automatically. I suggest that you not turn on your tv as the sustain boards will be taken out as well if you do. Replacing the high and ...

I actually have a 42' vizio and my problem is when first turned on the screen is quite dark and in about 20-30 minutes it will finally resolve itself to a regular picture. very frustrating since this tv was not inexpensive and of course it is out of warranty. i have 3 other tvs in my home and no problems ever and they are quite a bit older. i would never buy vizio again.

Picture problems Upon startup, the right 1/3rd of the screen has a trailing rainbow effect. This sometimes clears up quickly but sometimes takes hours. When it does clear up the picture is perfect. Then if I shut it off the whole process starts again. sometimes when the rainbow effect subsides the right side of the screen gets very dark almost black and the picture cannot be seen on that part of the screen. Is this a simple component that can be replaced of is it something more? I love the pict

Hi, I purchased a Sony Bravia model #KDL-52S4100 two years ago. About 7 months ago when the TV was turned on there was no picture for 15 minutes or so, then when you turn it off and on again half a picture will show with larger images on the right hand side of the screen. Other times there is half a picture and then when you turn it off it will come on with a full screen picture. Once it warms up the picture is fine. Is there any inexpensive solutions here? Thanks for any help you can provide.
There's a good chance you have failing electrolytic capacitors either in the power section or the inverter section or both.Any caps in these sections that look bulged at the top, or bulged/leaking at the bottom need to be replaced.If you ...

When I turn on my WS65611 rear projector TV the picture comes on perfect but after a minute it starts going static then the picture will come back on then it goes stactic. This continues for as long as the TV is on. When I get the menu to appear on the screen, the picture will stay perfect,, however the menu screen is in front of the picture.
A few things you could and should try, try something on a different input if you are using the coax connection just to know if problem exists that way, could be a bad tuner but that can be got around, also if on all inputs the set does have a hard r ...

LCD television starts normal, but after 2-3 secs, the screen turns black and remains black, no picture, but sound is still there.
All cables have been checked - all possible input channels have also been tested to see if they produced any images onto the screen.
When i look in a dark room to the black screen (with a flashlight), you can see (but very hard to see) some grey images (tv pictures) moving over the screen.

I have a SANYO DP46848, 46 inch flat screen hdtv purchased about 2 - 3 years ago. The screen goes dark on the left side (top .25% is ok). It sometimes fixes itself after an hour or so. Sometimes you can fix it by placing your hand on the dark spot for 10-15 seconds. There is a thin horizontal line about 1/4th of the way down from the top with the top of line ok when the bottom of line area goes dark. LCD Controller? or Main Board? or Power Supply or the Panel itself? I have a picture if that
