Question about Philips 62PL9774 62 in. HDTV LCD Television

Picture darker around the edges

Lamp is relatively new. Over time, unit has developed a dark ring towards the outer edge of the picture, all the way around. Another TV repair man told me that there's a mirror inside that probably has dust that's built up on it. I took the lower back cover off and cleaned the lenses that I could see, but he says this mirror is in the upper back section. I've taken all the screws out of the upper back cover, but it's still seems attached by something. I cannot get it off and am afraid of breaking something if I force it. Do I need to take the front cover off to get the back cover off? If so, I'm not sure how. I don't see any screws accessible to take it off. Any help would be greatly appreciated.

    The dark spot suggestion doesn't make sense in my case because there isn't just a dark spot on the image, there's an even kind of ring around the edges, more into the corners. It's not completely dark, the brightness just fades towards the edges.

    I have the exact problem with my tv. It is the exact model.

    I know this is an old post but I fixed this on this same model. There is a lense next to the DLP chip that has a film glued to it. The glue on the film is turning brown so you will need to remove it and you picture will be bright again. You will need to refocus your tv when you are done.

It seems to me that with "general" dimming to the most distal areas of the screen, we are dealing with overall bulb failure/intensity, a failure or lack of light receiptivity at the distal areas of the screen due to age or use, or some sort of uniform film build-up somewhere that is mechanically restricting the bulb's intensity. does this sound reasonable?

This may also be a spot on the bulb itself. Projection TVs use a high powered bulb to project the image. If something got stuck to the bulb, it can cause a dark spot. I would have a qualified technician look at it,

IH252 inc monitor bottom half darker than top.


Thin screen LCD monitor brightness controls operate several fluorescent lamps called "backlights" that are positioned behind the LCD display. Typically, they're located around the edges of the screen - sometimes just at the top and bottom, and other times at the left and right edges and others still at all 4 edges.

Fluorescent "backlight" lamp, inverter & connection wiring.

The lamps are miniature versions of those sold in stores. They require a support circuitry called an inverter that convert & boosts the level of DC to AC voltage performing the functions of a ballast in a traditional fluorescent fixture.

The reason a part of your screen remains dark is because one or more of the components in the picture above has failed and will not allow the lamp to shine. Replacement lamps and inverters aren't expensive - but requires patience and the ability to disassemble / assemble the monitor (which is usually harder to do than it appears) and solder. They are available various lengths and color temperatures (you must get a lamp that is identical or it will be noticed). If this is a new monitor - you ought to return it for replacement. If used, consider the cost of purchasing a replacement (new or used) vs. repair.

I hope this helps & good luck!

HDLP61W151 has dark spot in screen


If it happened gradually I would suspect the lamp--a photo posted here might help.

The other possible cause in a Optical light engine which might be very expensive to replace in this brand.

Dark black spots around the edges of LCD TV


this issue is tape from the edge of the panel falling onto the screen.You will have to remove the cabinet and the panel from the bezel(front cabinet).remove the screws from the lcd outer edge. Take of the tape.Be very carfull of the ribbon cable that goes to the lcd controller and to the lcd screen itself. They break easy. If you do , its over. you will need a new panel. to much money and work. best to leave it alone.I have fixed it several times for people with warrentys. It is just anoying but will not hurt your tv.

Image reduced by dark edges


An adapter tube has to flare out at the end or it will cut the corners off at the wide angle setting. Telephoto should be ok though.

Color is not good around outer edges of picture


When the colors are off around the edges on a regular picture tube TV, it usually means that the degaussing thermistor's solder joints have cracked loose. Another possible cause is that a strong magnet, such as in a stereo speaker, was brought very close to the picture tube and has magnetized the tube. Resoldering the solder joints on the degaussing thermistor and demagnetizing the picture tube should put the color back to normal.
