Re: Sanyo tv tuner identification

I have the sanyo part # 6450526084 . There is another number but could not find it online. There is a place called that might sell you the tuner outright as they mostly rebuild them . The are the cheapest place i know of . You want to use the contact link and tell them the part # and see if they can cross it for you as i gave you part number. The ID # you refer to is on the tuner shield that you say is missing . Or you can google the part # to see what you can find should start with 1AV4FBAM???? . Good luck

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.

Will my TV receive digital signals without an external digital converter?

Hi, John.
No your tv is an older standard definition tv with an NTSC tuner..that was the old type tuner for analog stations.
You will need to get an ATSC digital tuner in order to tune in digital broadcasts.

Luckily, you don't have to spend hundreds to get one.
WalMart and several other stores carry inexpensive digital tuner converters that are in the $30-$40 range.

I hope this helps you out on getting stations picked up, as without the converter, your tv would only be good for hooking up a dvd player to it, or for video games.

Good luck tio you, and have a good day.

I received a free second-hand Sanyo television (model #DS24425). When I got it home, however, and attempted to attach the cable to it, I realized the part where I'd make the connection was missing. ...

You are discussing about the antenna socket of your Sanyo TV. Sanyo has two types of fittings to this. The first type is the socket is screwed to the back cover of the set and a shield wire will go to the tuner of the set from it. The second type is, the in socket of the tuner itself [look like a steel metal box inside] will be projected out through a hole at the bac cover.
If your TVs connection is the first type, you can purchase a ne antenna socket and can be fitted on the same place and rewire it as it was. If it is the second type, tuner as a unit should be replaced. You have to desolder the present tuner out from the set and buy a new one and solder it to the same place. The number of the tuner is very important when buying it, and it will be printed on its cover itsef. OK>

Several things can cause a no-start condition. The EEPROM is my first concern. But before you even try to replace it you will have to resolder the Tuner on board. If you can pull the board out of this TV safely, do so. Where the RF connection is, this is the tuner. The tuner is built into the board, you cannot remove the tuner.Unsolder the bottom shield of the tuner. You will take the cover off and find about fifteen area to resolder. You must inspect very close to find these. The grounds that grasp the tuner cover will need resoldered, you can see where the solder is cracked. There will also be center pins in this area that will need resoldering as well. It will require lots of patience and skill to do this soldering. You do not want to burn the the PC traces as you will destroy this TV. After you rsolder and replace the tuner shield, then you may attempt to replace the EEPROM. The EEPROM location is U3201V. You will have to give me a Chassis number to find the correct EEPROM part. Other problems in the start up may be that the switch mode regulator will need resoldered. Location is U4101V.There are eleven pins to inspect. Also any radial capacitors in this are may be weak and may need replace. Please check these. I cannot remember for sure the values or location of these capacitors. I think one was 63 volt 10MF, this is known as the startup cap. Another cap was a 200 volt at about 2.2Mf. These are radial electrolytic capacitors. They are near the regulator I mentioned. Well these are very good leads for repair. I could go on and on.Seems complicated and, is if you have not worked on this model. You must have patience and skill to do this. My first concern would be to resolder the tuner. See what happens. Thanks for asking and show all hands of support.

Sanyo tv model it an HD tv?

You can view the specifications here:
Sanyo DS31520
I found no mention of the needed ATSC digital tuner so you need to acquire a converter box to receive broadcast signals after the changeover. Cable and satellite reception are not affected.
I reviewed the available converters and chose the Zinwell ZAT-970.

Digital capable

You will only need the converter box if you use an antenna. If you have a cable tv service, they will do the conversion on their end.

make sure your got the right cable mode selected through the remote or autual switch on back of tv. if not it youll only see cable channels up to channel 13 that means in is standard tv mode or air. once you selected cable autoprogram and it find all the channels for you. these newer sets, dont bother with looking for a cable switch, its all done automaticly when you hit that autoprogram button but it would be in the menu under setup.

Need an antenna block for a Sanyo DS25390

Was the block a cube about 1" ? You should be able to salvage one from an old tv. This block is used to isolate the antenna/cable from the "hot" chassis inside your tv. If you should find a used block ,make sure it does this. If you get one that gives you a direct connection to the chassis, your antenna/cable connector would give you a shock and probably burn out something in your tv when the cable is connected. Some of the Sanyo's have this connector made on to the tuner. If this is the case you'd have to either put a new coax connector in the tuner OR replace the tuner. Stargazer
