Sanyo DS20930 I was watching TV today when all of a sudden I lost the picture. I see only red/blue/black snow. The sound is perfect, I can change channels and get the different sounds. What do you think is wrong, and should I get it fixed or throw it away???

The problem with saying my TV is acting up, is you did not mention the model #, type of TV, tube type, projection, plasma, LCD. They all have different faults that can cause this. The first thing you do is to hook up signal to your video inputs if you have any and see if the signal works that way, if so then you probly have a bad tuner, or you cable box is bad.

I am trying to help my neighbor. She has a Sanyo flat screen tv Model DS20930. The picture she gets is a thin line across the center of the screen.


Hello
Set the brightness, contrast and colour control of that TV to minimum. Watch it in a dark room whether ther are thin white lines across the screen, at about an inch apart, from bottom to top of the screen. If there are lines, that TV needs screen control adjustments. That is, now the screen voltage given to the picture tube went high to some reasons. If you have confidence that you can adjust it, I will guide you.
Open the back cover of that TV. Locate the LOT [Line output Transformer], usually one red thick wire is connected to the top of the picture tube with the help of a rubber ****** and clip. In most TVs it can be located and can be seen as the back cover opened. There are two variable control, fitted, integrated to LOT. Normally the upper one is marked as focus, and the lower one is marked as screen. You shoud adjust this control to avoid these lines.
It is a live service, that is the TV must be switched on during this time, and take causion in every respect not hurt by yoursef and the TV. Keep the children away from you, and an other adult person beside you is better. A liitle turn counterclockwise will remove this problem.

Does your screen light up or picture comes before it turns off? This could be from your X-ray protection feature, you will have to check the power supply output voltages.

Sanyo makes a fine TV. You have a problem in the vertical circuit causing the line. You should not play the set in that condition because you can dammage the picture tube. Call a few local shops to get an idea of what they charge to fix a vertical problem on a 20" TV. If the cost of repair exceeds about 65% of replacement, toss it. In my opinion the newer sets are lacking in quality compared to older ones. In short , they break more often. If you choose to buy a new TV stay with a known Japanese brand.

Sanyo ds31590 picture's very dark and red


sounds to me that your picture tube needs rejuvenated.
You will need to get it done by a tech.
mechanical doesn't mean a thing when it comes to electronics.
Mechanics when working on electronics, end up costing more damage when you end up taking it to a tech.

Sanyo HT32744 Picture mostly green and blue


On mine 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.

Did you change the resistor by yourself? I am not sure if your TV has manual adjust on the back of the TV that you can adjust. Some times turning the TV Off and unplug it from the wall helps because it resets the TV. Check your Back ground color and see what is the dominating color. Blue, Green or Red. If this doesn't work please call a professional to look at it.
