Question about Mitsubishi CS-40507 40" TV

1 Answer

Picture faded to black, came back, faded again and had stayed black.

I've had this TV for ten years with no problems what so ever. A few months ago I noticed that the picture was blurry when I first turned on the set. It would clear up after being on for a few minutes. Then the picture began to overshadow black with a red haze. No adjustments would correct the redness. Then while watching a movie, the picture began to dim and slowly faded to black. The sound was still playing so I knew the movie was still on. After a few minutes, the picture slowly came back. It never got all the way back to normal brightness before it started to fade again to black. And it's been black ever since. I don't know where to begin. Any ideas? Is this TV worth fixing? Or should I turn it into a boat anchor? Any assistance would be greatly appreciated.

    Any ball park estimate of what the the cost to have the set checked out for 'loose connections' should run?

  • John DeJong Oct 12, 2006

    Thanks so much for the information. I lef the TV on all day today (forgot to turn it off) and noticed that the picture came back again, gradually and stayed for about 5 minutes, then slowly faded to black again. It cycled like that 3 or 4 times over a 6 hour period(that I saw) so I figure it shouldn't be that outrageous to fix. But what do I know, I'm certainly no expert.

It seems your set has a loose conection in the high voltage circuits,in fact by now it should have many loose conections in different areas like the power supply and the horizontal deflection circuits,if you are familiar with tv service you can use the information as the first step to take,some of the loose conections are hard to see even for the trained technician but the one giving you this problem should not be hard to see,if you are not too familiar with tv service be safe and call for assistance from a servicer a least for an estimate.

    It depends were you are but it should not be expensive.You need to consider there will be a trip charge and then an estimate charge.

Tv is on with no picture or sound, only 4 months old!!


Hello
The power supply regulator board to your set has the fault. If you try to open the set, or try to repair it by yourself, the warranty will void. The set must have warranty as it is new. Why do you spend for it? Just contact the nearest authorised service center for Sceptre. the components in this set will be very hard to get from open electronic spare part market, and will costly too.

Hi. i have sony w120. its not new, i bought it cca 3 years ago. I didnt use is for a quite a while (but my family did), so few days ago, i realized when i take pictures, pictures are somehow blurry,...


Please go to Setup menu and select Initialize option to reset camera to default settings that might solve blurry picture problem, if that does not help then its technician job to adjust focus of camera.
Thanks.

Blurry Picture


I too had the same problem where my HT30744 TV would lose its color or picture would get blurry. My mom's HT32744 would have the same problem too. They both are refurbished models bought at Value City Dept store. If I gave the cabinet a good hit it would mostly fix the color, but it could also make the picture go fuzzy too, a clear sign of just a loose connection somewhere.

So after my wife telling me she was sick of this almost 2 year problem and she was going to buy a new TV on the weekend, I figured I had nothing to lose. So I took the rear cabinet off, unseated the card mounted on the picture tube, applied a little dielectric grease on the connector on the card and reseated the card, removed, re-greased and reattached the card. I have had no problem with either my or mom's which I did the same to since! This is an easy fix that anyone can do. The hardest part is moving the TV and reassembling the rear cabinet. Do not pull the cabinet back out more than you have to, to ease the reassembly of it.

Blurry edges


I own the same model of tv and have owned it for over 1.5 years. I moved with it twice. I had this problem about a month ago. On both vertical sides the screen became very fuzzy, yet the center remained clear. When turning the tv off and on I also noticed very wierd red, green, and blue lines streaming across the screen before the picture comes up or after it fades. I found no solution or cause to the problem. But I had two "long-boy" speakers from my panisonic 5.1 surround sound system setup right next the tv on either side. I set the center channel on top of the tv with the receiver on the shelf below. I thought well maybe some how the speakers were cause some sort problem in the tv. I moved the side "long-boy" speakers from directly next to the tv to about 6" away and removed the center speaker from the top of the tv. After several days of normal use of this configuration, the tv turned like normal and the fuzzy edges were gone. The symptoms lasted for around two weeks, and the several days after I moved my speakers. My only guess is that without a deguassing feature, it took several days for the magnitism to return to normal after repositioning my speakers.

Blurry/Hazy picture on Philips Tv


as your problem is the picture has become blurry/hazy 1 it sounds me that there is a little sparking near high voltage section that is near flyback transformer.please get it check. 2 if it is ok then focusing anode wire going to crt base from flyback transformer is not making proper contact due to some foreign material deposited on it. please call tech person if you ae not aware of it as tv is a very high voltage device.

Dark picture (HELP)


Open up the back of the set but be very carefull. Notice a large black block with a large red wire that runs up to the picture tube. on one side of that large block where the thick red wire is comming out of are two controls, one should be marked focus or F and one should be marked screen or S. With the set operating normally and not touching anything else, slowly turn the control marked screen or S clockwish till the picture gets bright enough. If you go too bright the set will shut down or you see small thin white lines so back down on the control. then touch up the focus and your good to go. good Luck.
