Mitsu CS-35805 - vertical distortion issue

We have just brought our set home from being repaired - the picture would constantly fade to black after staying on for a few minutes - the repair was relatively cheap and only replacement was a new circuit board, but recently the picture has gotten worse. It ranges from the picture constantly distorting vertically by bowing at the corners and other times simply compressing the image vertically all together. Also if the screen were to brighten, or there happens to be a white background the image would just warp randomly and then return to normal. Sometimes you won't notice any problem with the picture, but there is always some issue happening 80 % of the time. It happens on every input and there will always be a very low hum coming from the back of the set when this occurs. If it is a connect issue with the previous problem we had, then that can be covered under the warranty of the repair, although it is a heavy set and a pain to transport. Thanks for any help.

    Sorry I forgot, he told us that the original plan was to replace the circuit board, but when we got it back he said he just replaced five capacitors and charged us less. Even if it is covered under the repair warranty, I am wondering if this can become a reoccurring issue, if this is the case, it won't be worth the effort of hauling it back to the shop.
    Thanks for the input

I highly doubt the circuit board was replaced, you had a simple 2 minute repair I'm sorry to say. They only re soldered the CRT board or the fly back connections, very common on this TV set. You now have a power supply issue, or a vertical drive or output problem. If you just brought the set home, I would contact the repair shop and see what they have to say and ask them the part number for the board they replaced. bet they say they forgot or don't remember. Good Luck

My picture is distorted ,sound is good but i also have vertical waves on sides also picture runs out of both sides like aspect ratio is out ,it is set at 4.3 is this still a convergence issue or something...


Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded overs. To get fixed either call in a local TV repair company or goto sites such as Tv Repair Kits to get a repair kit with instructions. Here is there link.

Green Convergence vertical line appears to be distorted and not streight


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*Screen Looks 3-D
*Colors wont align

Picture is distorted


Not knowing the model or brand that you have, I would suspect you have a vertical deflection issue. Have a repair shop check it out. Should be cost effective if the set is not too old.

One thing you should not do with electronic devices which have a start up proceedure is to turn the power off, and then on again without a wait of about five minutes. Some equipment manuals warn you about this, and specify a longer period. The start-up has to have time to reset. It will be more likely to reset if you do not leave it on standby, and even unplug it. In your TVs case you need to describe the distorted picture as it may give a clue to a fault, or incorrect start-up. The horizontal line indicates the frame timebase had stopped working. No picture could be a fuse blown inside the set, or a timed cutout which may reset after a time. Try after several hours to see if it comes on. If it is just the frame timebase (vertical) it is worth repairing.

Sorry to be the one to inform you Sheri, but this set is known to have several bad capacitors in the sweep as well as the power supply. Unless you have an ESR type capacitor checker, your going to have to take it in for service, by a pro. Hope yopu did'nt pay to much for it. Good Luck
