    same problem, replaced bulb, worked great for a while. recently picture quality is very poor. no depth in picture. poor contrast, glowing faces. it's also fuzzy. could it be the bulb again? last one went dark and blew out very quickly.

    I have a Toshiba 52HM95 DLP and I am having the same fuzzy picture on dark scenes. Peoples faces look shiny and the colors are not good. Had the TV for about two years now and have been through two bulbs. Also my picture is flickering pretty consistently now - it seems to be getting worse. It doesn't matter what input the TV is on. Is this a bulb issue? I don't want to pay to replace the bulb to find out it was really something else.

    Please Help!!

    same problems across the board, the only time it doesn't seem as bad is if i'm watching the program in hd, but then the flickering is worst....

Well I finally had the TV picked up by a Toshiba recommended repair place and they are saying that it is a bad Optical Block, also known as the Light Engine. Total for pick up, parts and repairs is $827.00. This seems ridiculous to me when brand new TVs are so much cheaper now. I don't think I will pay that much to have this one fixed.

    KBANDJOC - I could use your or your husband's help. Where is the color wheel and how did he get to it? Please be specific as possible. I opened up the back of the TV that covers the lamp area and the inputs area. I was then able to remove a flat metal bar and a slanted plastic piece to get to and clean the top of the lens. Did your husband take the whole front screen off of the TV as well? I tried but it seemed stuck on the front bottom part of the screen. I don't know where the color wheel is or how I would get to it. Where is the light engine? Is this the section held in metal between the lamp and the lens? Help Please!!

The problem is the color wheel. Poor design by Toshiba. Rear cooling fan brings in the dust and it sticks to the color wheel like a magnet. The housing is not air tight and dust collects on the wheel. Not an easy fix, but if your a little handy with electronics it's not hard. Unplug the power and remove the lamp. Shine a flashlight in the lens inside the TV. You will see the the color wheel. It should look faint in color but very clean and clear. If your set is a couple of years old it will have dust around the outer edge of the wheel. It's worth the time it takes to clean it. Takes about 2 hours. Remove the back panel, not the front. Remove the engine, remove cover and very carefully clean wheel with soft cloth. Your set will be like new again.

Hey all...just to let you know, I had noticed a post that said the individual prior to getting or ordering new parts, he took the tv apart from the back, and cleaned.

My husband spent the better part of the day, vacuuming out and blow drying on cool all the dust and such. after doing this the picture was worse, HOWEVER, we noticed the flashing was gone. SO, he took it apart again, and this time, very carefully took apart the compartment holding the color wheel. He took out the lens, cleaned it with a lens cleaner cloth. Took out the color wheel, very carefully cleaned the wheel, cleaned out the whole inside of that compartment, put it back together, and VOILA!!!!!!

BRAND NEW PICTURE EVEN BETTER THEN WHEN WE GOT IT.... no lies, no problems, it was extremely time consuming, but I ccan't describe the difference.....UNBELIEVEABLE and no spending a grand on a part.

Don't hold me responsible for any problems, but this just worked for us, and my tv is NO LONGER FLICKERING,, NO MORE LAVA LOOKING COLORS, NO SHADOWS.

JUST CRISP! WOO HOO, I DONT HAVE TO BUY A NEW TV... yet.

    Take the lamp out. after you take the flat metal bar out, and then take out the 2 screws at the bottom, and a metal tray will slide out. The color wheel, lens and all are on the metal tray. carefully take the top of the little thing off and you can get to all of it to CAREFULLY clean it with an extremely soft cloth. then put it back together....:)

Dark, fuzzy picture


The fluid in the CRT bulbs is most likely cloudy. Check the blue to see if fluid is clear. If fluid is clear, then likely your flyback transformer is failing. I assume you already check the brightness and contrast settings on the tv.

Can bulbs go in cameraz as evritime i use my flash the picture is dark and fuzzy


The capacitor that charges up can weaken, in time, but usually the zenon bulb will either work or it won't. You may be having a timing problem with the flash and the shutter. Also, some cameras have trouble focusing in dark scenes, also, and that may be happening in your case, in addition to the problem you're having. You can try other scene settings, to see if the camera operates better in those modes. Otherwise, you will have to have a repair shop check it out. Make sure you get an estimate before you do, since repair can be expensive. Wish there was an easy answer and fix to this problem, but there just isn't.

My flash bulb doesn't work, picture are dark


Do you have it turned off? Is there a picture of a lightning bolt with a line through it? If so, press the button with the lightning bolt until the screen shows a lightning bolt and an "a". Also, do you have the camera set on a scene mode such as night? The flash won't go off in some scene modes.

Picture getting dark


My jvc 27" tv was so dark I could hardly see any night scenes, even with the bright all the way on. If you push the sleep button, let go, then hold down the video and display (together), the service menu will come on. Scroll down to #7 (too dark) and adjust the brightness there. Works immediately. Good luck.

Darkening tv picture


The Picture tubes(not bulbs) do and probably are weak. There replace should only be done by a trained service person. One reason would be the hI Voltage issues related to the crt's, as these tubes store alot of HI voltage even after its unplugged for a while, and another reason would be that these tube can very easy implode then explode and that wouldnt be a pretty sight. Third would be the alighnment involved after all three tubes are replace. There ba cross hatch generator and alot of time involved with the alighnment. Please seek a pro to assit you when your ready to spend at least 900 TO 1000 bucks. Good Luck
