Question about Sanyo DP26648 LCD TV

Open Question

My Sanyo DP26648 is completely dead. If I turn it on, the power LED comes on for about 5 seconds then goes out. I can repeat this twice, and then the power LED won't even come on. Unplugging and then replugging the TV will once again allow the Power LED to come on for 3 cycles in attempting to turn on the TV. I guess replugging in the TV allows a capacitor to recharge and power the LED? Is this TV repairable or is it time to replace it?

It can be the 24vdc power supply problem which supplies the power for the backlights inverter board, or the backlights inverter board is bad, or T-CON board is bad, you need to do this when the screen goes black:
First, look at the screen in darkened room to see if you can see any slight glow from the screen, if it does, then the problem can be the T-CON (not getting the 12vdc) or the main logic board not feeding the signals to the T-CON board.
if not, next place to check will be the power supply module, make sure it has 24vdc which is required by the backlight inverter to work, the reason for not having 24vdc can be from bad DC filter caps (leaking/bulging top, high ESR) or short circuits in the inverter board which will cause the 24vdc supply to go into shutdown mode, so you may have to disconnect the power cable that feed the inverter board to see if the 24vdc will work without the inverter board hookup, you will need to apply about 3~4 amp of load to the 24vdc to make sure it can handle that. There are fuses on the backlight inverter boards also. So there is some troubleshooting you will have to do to find out the causes of the problem you are having.

It has knocked out your power supply board...It can be changed very easily just by taking the back off the set and tracing it from where the AC cord plugs in. Then unplug and unscrew the board. The part number should be 1AV4U20C17201. Match this number from your board and do a search with the number on Ebay or shopjimmy.com or google to get availibility and price. You can even do a search with the model number as well. Just be sure the board numbers match completely. But first replace the fuse as this could be your sole problem since you had a power surge.

Had a power outage and my sanyo DP26648 will not come on, it was on a surge bar, the green light comes on for about 4-5 sec and then goes off is there anything I can do to fix it


Fault with the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.
http://electronicshelponline.blogspot.com/
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time.

Unit turns off after 3 to 5 seconds


This does not sound like a capacitor problem.



Bad capacitors usually cause the TV to have a SLOW startup, not so much to shut off after they are once started. Of course both are possible, but the former is a whole lot more common (based on my experience).



Also, bad capacitors are usually easy to spot even with a naked eye. Just look at your power supply board and see if there are any that are bulging.



Not seeing any is not a guarantee, but more often than not is sufficient to rule that out as a possibility.



Finally, here are some repair and replacement alternatives for DP26648 power supply issues:

What could cause a 27" Sanyo flat panel dp26648 to lose picture, but keep sound?


There are two reasons why your Sanyo DP26648 would has sound but no image and both are equally likely in our experience.

First, you may have a problem in the section of the power board that supplies the backlight module (called inverter) with 24V.

We've seen that several times and the problem is usually minimal - only electrolytic capacitors gone bad - and other times not so minimal.

We have a repair service for that power board and we may have some boards available too...check out at

I have the radion shack hdtv remote. Cat no


Download the manual and codes from here

http://www.remotecentral.com/cgi-bin/files/dl.cgi?file=others/radio_shack/15135-manual.zip&area=other

Here is how to set the code...

1. Turn TV on
2. Press TV button on remote
3. Hold P button on remote until LED blinks twice
4. Enter the first 5 digit code for Magnavox TV's
5. Press Power button - TV should turn off. If TV doesn't turn off repeat steps 2-5 with the next 5 digit code, until either TV goes off or run out of codes.
6. If out of codes use searching for code method below...

TV codes for Magnavox

10047, 11454, 10054, 10154, 10000, 10250, 10051, 10180, 10060, 10030, 10171, 10092, 10706, 11913, 11904, 11755, 10019, 11365, 11254, 10802, 10386, 10282, 10020, 10187, 10186, 10024, 10179, 10096

Searching for code

1. Turn on TV.
2. Press TV button on remote
3. Press and hold P button until LED blinks twice
4. Enter code 991 on remote - LED blinks twice
5. Press 1 - Device key blinks twice
6. Press Power button once
7. Press and release CH+ key until TV turns off.

At this point in the manual, the manual is only correct depending on what type of TV you have.

In the manual if you press the Power on button the TV should turn itself back on, the fail to state that not all TV's turn on by the power button, the majority now are triggered to turn on, on channel change, however you can't use channel change here to check it as you'll go to the next code... here is my solution...

8. Turn TV back on either using original TV remote, or buttons on front (most TV's if you change channels they come back out of standby mode, very few now turn on by pressing the power button).

9. Press Power button on remote - TV should turn itself off again.
10. Press P button on remote to lock in that code.

If the device does not turn off press CH- to go back through the codes, press and release P button when TV turns off.

Finding code

If you used the search function you might want to know what code it's using. To do this follow these instructions...

1. Press TV button
2. Press and hold P until LED blinks twice
3. Enter 990 and LED blinks twice
4. Press 1 and count number of times LED blinks this is the first digit of your code (e.g. 1 blink = 1, 2 blinks = 2, etc).
5. Repeat step 4 pressing buttons 2 - 5 for the other digits (e.g. for the second digit press 2 count number of blinks.. etc)

At this point the manual doesn't tell you how to get out of this mode, I presume pressing any other button on the remote other than 1-5 will take you out of this mode, either that or leaving the remote alone for 5 minutes.

Programing to a tv


http://www.hifi-remote.com/ofa/codes-tv.shtml#tv

If none of the codes work then we have two other solutions:

1. Searching For Your Code

If you have tried all of the set-up codes for your brand of equipment ,or yourbrand is not listed, and you are still not able to get the unit to respond, trythe following procedure to search for your code.
If you don't find a code that works, the remote will flash four times when youreach the end of all the codes for this device type.
  1. PRESS the button for the device you want to program, (TV, VCR, CABLE, etc.), then RELEASE.
  2. PRESS and HOLD the SETUP button until the red LED flashes twice, then RELEASE.
  3. ENTER 9-9-1 (two blinks on the remote)
  4. ALTERNATE slowly between the POWER key and the DEVICE (TV, VCR, CABLE, etc.) button until your device turns off. (On VCR, LD, and CD players use PLAY instead of POWER)
    Make sure that the remote is pointed at your device during the search, You may have to press this sequences of buttons up to 100 times to search the entire library of codes.
  5. When your device turns OFF, PRESS the SETUP button and RELEASE it to lock in the code for your device.

2. Learn the buttons from the original

Line up your original remote and the head-to-head before completing thefollowing steps.
  1. PRESS and HOLD the SETUP button until the red LED flashes twice.
  2. PRESS 9 - 7 - 5, the red LED will flash twice.
  3. PRESS the DEVICE key where you wish to learn the function. The next 3 steps must be completed within 10 seconds.
  4. PRESS the button that will receive the learned function, the LED will flash rapidly.
  5. PRESS the button on the original remote to be learned.

Now you can repeat steps 3 through 5 to learn other functions onto other keysor press and hold SETUP until the Cinema's red light flashes twice to lock inyour new feature. (If the red light does not blink twice, stop and repeat stepsthrough 6).
To test the new feature, press and release the device key in which the newfeature was learned followed by the key on which the feature was learned
