Vertical sweep failure.
It will be an I.C. with a part number that probably starts with an LA_ _ _ _ and be on a heat sink in the vicinity of the connector going up to the yoke. Try replacing that. But first, check all the electrolytic caps around it for testing dry (sorry - takes a special meter to do it in circuit) or just replace them. May have lost power to the I.C. as well. Look the I.C. up in the free NTE crossreference at nteinc.com get a diagram of its pinout to find what pins the power and outputs are on.
Hope ya fix it!

Is this a HD ready tv if not what would help?


Based on the specs for the TV, the DS31520 is not an HD-ready display. It is at best an SD display with an NTSC (analog tuner). (Picture resolution: 330 lines, video input 660 lines) OTA ATSC signals are 480i (SD), 720p or 1080i (HD) where those are the number of horizontal lines of pixels. The manual is available here: http://www.sanyotv.com/DS31520%20%28ESF%29%203178--.pdf .

This is a fine TV for analog cable or OTA TV with a standard digital to analog converter box (which only give SD output). The TV has composite video and S-video inputs (again limited to SD).

For HD, you will need a new TV screen that can display more rows of data.

I wish that I had better news for you.

I had comcast before but now i don't ,don't use a converter box and somehow I was getting cinemax and other channes on the tv,now i am not I auto programmmed the tv again and mess the the channels...


> I had comcast before but now i don't, don't use a converter box and somehow I was getting cinemax and other channels on the tv
Comcast was providing Cinemax and many other channels as part of your paid services and you will not receive these unless you are a subscriber. There is a good selection of free broadcast channels unless you live outside city areas. If you do, you will then need an external antenna and probably an amplifier to get more distant signals. Auto programming will not find the channels you were receiving from Comcast so there will be only accidental channel duplication; for example, if your former channel 10 was NBC, it may be channel 7 when receiving signal from an antenna.
There are essentially no more 'Analog' stations still broadcasting, they are now all 'Digital.' The abbreviations 'Std' refers to the aspect ratio (H/W) of the picture area and 'Hrc' and 'Irc' the available resolution or how many pixels and lines on the screen.

I cant stop the tv monitor screen from jumping it has something with the dvr


Hello What type of TV do you have, analog or digital? If you have an analog TV and the screen is rolling it is the vertical hold. Because the vertical hold operate on 60 cycle which the same as AC line cycle. The 60 cycle in the vertical hold is as a oscillator or timing circuit. When the TV pick up the image for the NV devise, they just don't mix. Why, because image intensifier tube in the NV devise is operation at 25 to 50K Hz or cycles. The vertical hold circuit pick up on the 50K Hz signal which mixes with 60 cycle timing circuit causing the screen to rolling with lines across the screen @ 60 cycles. Digital camera and digital camcorder with digital TV will help, or a image inverter that takes this 50k Hz signal and covert it to some that analog TVs can use. GB...stewbison

31'sanyo tv analog has a white horizonal line thru it


There is a failure in the vertical amp section. This can be the main output IC, or any of the support components in this area.

An experienced tech can troubleshoot the set, and determine and service the fault.
