Re: Analog TV, We don t get a picture, just a very narrow...

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 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: .

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.

We have a 27" MTS Stereo color TV. There are white horizontal lines at the top of the screen. We do have a DVR with Direct TV. How do we fix?

U can't.Only horizontal lines on the top parts of the tv screen or the lower parts of the picture screen.Or very light horizontal lines mix in with the tv screen pictures.The "CRT" the picture tube is slowly dying of old age.Quicker than they supose to.The late 90" these problems case show up alot more in standard tvs using CRT tube.Because the CRT and analog design about to be faze out of the market place.The glass molding and those radiation matrials,they used to make those "CRT" picture tube materials,not as good as before.

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.
