My Sanyo TV Model number DS20425 will not stay on. It comes on for about 2 sec then turns back off. You can do this for about three times then it will not even try to come on.

The best option is to try a different component cable and inspect both ports for any wear.

Alternatively, try the same cable on another TV if you have one near by.

If you don't have the code, you could do a code search and when you hit the code search button on the remote, continually hit the power button until your tv turns off. Then save it, but it may take awhile. You may have to hit the power off a 100 times or more if you don't have the code.

Try these found soultion on Fixya!

1. Manually turn on your component.
2. Press and hold the component key you wish to program, in your case the TV key.
3. While holding down the component key press the four-digit code using the number keys (0-9) to enter it.
4. After the fourth number is entered, the illuminated ON-OFF key turns on. At this time, release the comonent key. If the illuminated ON-OFF key turns off, you have entered a valid code.
NOTE: For Sanyo TV it could be any of the 8 next codes:
1004, 1048, 1049, 1073, 1080, 1162, 1169, 1180
Good Luck !

If that fails try the manual search as follows:

For a manual code search and entry:

1. Turn on the component
2. Press and hold the component key (TV, DVD, VCR-AUX, SAT-CBL)
The illuminated on-off key turns on and stays on
3. While holding the component key down, press and hold the ON-OFF key. The illuminated ON-OFF key turns off.
4. After holding down both keys for three seconds, the illuminated ON-OFF key turns back on.
5. Release both keys. The illuminated ON-OFF key remains on
6. Press and release the ON-OFF key repeatedly until your component turns off. Wait four seconds between each keypress. Each time you press the ON-OFF key, the illuminated ON-OFF key blinks, and the next code in the list is sent. This process continues until all of the codes in the code lists have been searched. If your component turns off, you have found the correct code. (If it cycles through and the illuminated ON-OFF key blinks four times and turns off, all codes have been search. The manual code search method is exited.)
7. Once you have found the correct code, you must save the new code by pressing and releasing the STOP key. The illuminated ON-OFF key turns off. You must press the STOP key to save the code or the correct code will not be saved.
8. To confirm that the component is programmed with the correct code for max functionality, test the component. Attempt to control a variety of the component's functions with the remote. If some of the features of your component do not work try programming the remote with a different programming method. Be sure to retrieve the code your remote programmed.

Please let me know if this works for you.

Thanks and good luck!

If there is problem with an inverter or a back light, the lights will come on for about 2 seconds and then shut off.
The Sanyo DP42484 television has a problem with poor quality back lights. I had one that had three bad back lights. I replaced them and it fixed the problem. The TV now comes on and stays on.
Replacing the back lights is a very tricky problem. You have to completely disassemble the entire TV to expose the back lights. The hardest part is removing the LCD glass without damaging the very delicate ribbon cables that connect it to the rest of the TV or cracking the glass.
You then have to reassemble the television, except without the LCD glass. You can then power up the TV and see which back light are not illuminating.
The back lights are 950 mm long and 3.3 mm wide. There are 12 of them. The ends are coated in a silver paint for conductivity. They are held by metal U-shaped sockets at either end. In the middle of the length of the fluorescent tube is a C-shaped plastic support to hold up the center of the long tubes. This plastic is very brittle and breaks easily. Try to slide the tube to the side thru the plastic support. If you try to spread the support wider and pull the tube foreward, the C-shaped plastic support will break.
I searched for an exact replacement, but I was not successful. The closed I could get was 950 mm long and 3.0 mm wide with wire ends. I purchased these from http://www.ccflwarehouse.com for $25 each. Part number CC30950. I bent the wire ends back and soldered them to the metal sockets. When the 3 bad lights were replaced the Television came on and stayed on.

i think the convergence amps are weak, or the akb circut has caused the tubes to go bad, google your model number to see if it is in the tube problem. sony made some projos w/ bad tubes in them. tv lasts only three or four years,no cause i had one

CHECK THE INFRARED LIGHT ON THE REMOTE AT THE TOP.. WIGGLE IT TO SEE IF ITS LOOSE, IF SO, SIMPLY OPEN IT UP AND RESOLDER THE LIGHT... SOLDER GETS OLD AND BECOMES LOOSE SOMETIMES

need a code for neon 32"tv model no 3298

Just ask at http://manualfox.com/remote.htm
- they find you every remote code. Send them model #s of TV and remote!

BE VERY CAREFUL!! This area is part of the output transformer which produces the HIGH voltage to the screen. The one to adjust is the SCREEN control. I would be surpised if just moving the TV would have caused this to have altered.

The Sanyo part number is: 6450656934
It used to cost about $25, but is no longer available from the distributor I use. Hopefully the part number will help. Realize that most universal remotes should work just fine. Just be sure to get one that has a menu button.
