Finding schematics anywhere has become a real chore; even Sams doesn't bother to try to keep up with the flood of new stuff coming out all the time.
You state that you can fix it; well maybe. If you have a multimeter you can at least check a few things:
Locate the flyback, it's a largish clump of plastic normally found near a corner and with a large diameter cable sprouting from the top and attached to the CRT. Right close to that, you will find a heatsink with one (sometimes two) larger epoxyed components.  The one with three leads is the flyback or horizontal output transistor. If there is a second component, it will be the damper diode with only two leads although these are normally inside the transistor now.
If you have a diode symbol on your meter, use that, if not, choose the the 2K resistance range. On the transistor, check between the outer leads, swapping the meter leads (and their polarity). If you measure something low that isn't quite a short, it's probably OK. Check between the center lead (collector) and each outer lead (base and emitter). The terminology changes for a FET but bipolars are still more common in this position. Regardless of lead orientation, none of the measurements should be as low as the first between the outer leads. If you seem to be measuring a piece of wire, that part is bad.
Now, replacing that part may just waste money since it is fairly common for the transistor and the flyback to fail together and you aren't likely to find a flyback anymore for that set.
The transistor PN will start with an SD or SK; you need to add a '2' in front for a complete part number; i.e. if it says 'SD1142' the full number is 2SD1142.
You are not likely to find the part you need and most suppliers have minimums you must meet. That part probably isn't more than $10 US if you can find it. If you can't, try NTE:

Considering all the problems folks are having with their flat panel TVs, saving your CRT version isn't a bad idea.

I have the remote for my sanyo mts tv but i cant find out how to get it to switch to video mode so i can play games on it there is no button


There is button on your remote labeled TV/AV . Press the button to get a blank screen with AV written on the screen. If your game device is connected at the back to this AV socket ( Yellow / Red / White ) you will see the game menu display.
On some of the TV remotes it might not be written TV/AV but INPUT SOURCE or just a picture of a TV screen with an arrow pointing inwards ( that LOGO is the universal symbol for INPUT )

I have a sanyo mts TV, it is stuck on video 1


Yes.  Power down the tv and unplug it for at least 2 minutes. Then plug it back in, and power it back up. That should give it a clean restart. 
Let me know if this works for you.

Sanyo DS31590 and converter box


I just checked the owners manual online. Looks like this model only has an NTSC analog tuner. No ATSC digital tuner built in.

If you use cable or satellite TV services, the digital converters won't help you. The coupon-eligible ones are strictly for use with a traditional antenna. If this is your situation, ignore the remainder of this message.

If you use a regular TV antenna with this TV, then, yes, you will need a converter box. FYI, the Insignia model at Best Buy and the Zenith at Circuit City, and elsewhere (radio shack) have gotten good reviews from early purchasers. More converter box models will be available in a few months time.

If your current reception with your antenna is poor (snowy), you may have problems receiving the new DTV signals. If not, you should be pleasantly surprised with the quality of the DTV signals - and the extra "virtual" channels. Try the converter box using the RCA video and audio inputs, for a slightly better picture than with the coaxial cable inputs.

Good Luck

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.
