Anyone else with this Toshiba 40G300U have lighting (like flashlights) shineing from all four corners? Is this typical for this tv or is mine defective?

I just bought this model after Christmas and it doesn't have any flashing corners. Sorry, sounds like you might need to return it. I believe there's 30 day return policy on TVs from amazon.

We had the same issue after we installed the TV in 2 months ago. The brightness of the TV cycles through the lamp opposite from the TV - if we turn the lamp on, the screen gets bright within 3-4 seconds, and if the lamp is off, the screen is back to darker and dimmer image within 3 seconds. We have tried other lamps to see if interferences the TV responds to, but this is the only lamp that works that magic. the two devices dont share the same electric source either.

When I had this TV there was glare from our lamp in the living room when we watched at night. The technical solution was to turn off the lamp. :)

White spots? Are they small? These could be bad mirrors in your processing board. My TV has 2 white and several black ones. Replacing the processing board with the mirrors is about 250... This is not related to the bulb it is a separate issue.

We have the same problem with our TV. The screen is normally very dim, then gets very bight. We've never had the screen go black. We have also noticed the same phenomenon that J. Wu mentioned about the lamp.Have either of you solved this problem? Were you able to exchange it?

This happens on my Panasonic Plasma on rare occasion (3 or 4 times a year.) It also happens with my Vizio LED. I believe its not a TV problem but a cable problem. I have Comcast and sometimes I need to unplug my cable box for a few minutes to re-boot it. Sometimes that works, but more often I'm just getting a bad signal from some unknown link in the chain from a live feed. It annoying but has never lasted. The other 99.9% of the time both TV work great.

I am going through my second 40XBR4. The first had what seemed like flashlights shining diagonally from the upper left and right corners in dark scenes. I exchanged it for a second one and it sucks as well. I think the second one is going to be returned pretty soon as well and no more Sony for me.

I just purchased a 750 and out of the box it already has a 1 inch long area on the red toc that looks like it is gone. It's a tiny sliver on the right, but from across the room you can see on the outside of the glass that it reflects light differently and looks less than perfect :o( ...Can anyone advise me on what I should do? I didn't purchase an extended warranty. Other than that, this tv is AMAZING!!!!!! seriously... AMAZING!!!! Words cannot describe. Literally, OMG, OMG, OMG as I watch a Blue-Ray disc.

That usually means the DLP lamp is defective. Try unplugging the TV from the wall to reset it and if it still does the same thing I would say you need a new DLP chip.

No I have not seen that issue even up close. I have although done some messing around with the picture settings and by no means am I an expert. I would try some different settings or return it for a new one because of the price we have all had to pay for it. It could have even been damaged during shipping or not have set long enough before it was turned on the first time. I have the exact tv and the blacks are deep blacks and the whites are true as well as grey and all other colors. I let mine sit for eight hours after it was mounted on the tv stand before I turned it on for the first time.

I've had this TV for ~9 months and have not noticed this ... There is a light sensor in the TV; perhaps sunshine or ambient light is causing this?

If your picture is dim then a new lamp should make it like new again. It is doubtful anything other than a degraded lamp would cause a dim picture. I wouldn't expect to get a refund if the lamp works. I bought one but really couldn't tell a difference. I don't know if the TV just didn't need a new lamp or that the off brand lamp isn't as bright as an OEM lamp. Personally, I'd stick with OEM Sony parts. They cost more though.

Never had a problem with brightness. Make sure you check your settings, some will make the picture dimmer. Also make sure the mirror inside the set is clean.

Actually online aficionado......The new Samsung LED's are WORSE. It is mentioned in cnets reviews and some have left comments here on amazon. One guy mentioned how he can see streaks running through his new LED tv in a dark room. So yeah... LCD's only look good when the lights are on.My friend has a panasonic plasma that he games on a lot. NO BURN IT. There is temporary image retention but that goes away fast.

Its really bright if you put it in the vivid preset. To tell you the truth when i watch tv i cant tell if its a plasma or an led...the only thing that gives it away is at night time when its really quiet, i can hear a faint humming coming from the tv. Other than that, i believe this is one of the best tvs on the market today!

Although this is an old question, my answer may help new buyers. I've owned this TV since 2010 and the "ghosting" effect on darker images in games has annoyed the H out of me for the last 4 years. Now that my warranty is about to run out I don't feel guilty about buying another tv. Apparently this is a common complaint on Samsung LED's.

S.C.Thank for the help! I think the swelling in my head has gone down a little...I went ahead and purchased the Toshiba. From what I can gather if I get an HDMI cable, if I calibrate the tv correctly, and if I watch each program in the correct aspect ratio, then I shouldn't have a problem.Thanks again,Matt
