Either a reflection or you are getting some light (blue?)

If total dead it needs to be opened to look for a fuse or bad caps in power supply---see attached photos of what bad caps look like.

SOURCE: how do i replace the

You are actually referring to the buffers, the circuits that actually command the pixels - in this tv they cannot be replaced, they are glued on the side of the LCD screen and cannot be moved. If for some reason one of the buffers has failed then the LCD screen is defective for good, no way to fix it.
You could replace the entire screen but, when the entire tv costs less than $350, paying at least $200 for another new one is not worth the effort. You could try to find out a tv that is sold for parts and has an good screen - on Ebay you could pay for it less than $150.

SOURCE: Sanyo DP 42647 has no power it won't turn on at

Hi,

The issue you describe is consistent with a power supply board issue. This is the board where the AC goes to. This problem may have occurred as a result of irregular power supply, or excess power supply or power surge.

The TV is receiving current but cannot circulate or transfer the current to other necessary part of the TV because of the defective power supply board. You might be lucky it's just a blow fuse. Also a defective transformer can cause your TV not to power on.

All these can be checked on the power supply board.

But more often bad capacitors causes problem on the power supply board. I do not think the power board needs replacement, rather those defective capacitors is causing this issue. Open unit up and take a look at the power supply board.You will probably see one or more electrolytic filter capacitors that are bulged up in the top-not perfectly flat like the others.

The value of these capacitors will be different, most likely they will be somewhere around-820 to 2200uF/25 V( or /10V sometimes)

You can replace them with same values but I would recommend the voltage rating to be higher(like 35V for an original 25V) for reliability purposes.

What happens is,these bulged top capacitors will cause a low and unfiltered DC voltage=main board will malfunction(the relay will keep clicking until the caps are holding enough charge to bring the voltage up over a threshold point).

You can buy these capacitors at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors). After replacing these capacitor(capacitors) most likely the normal operation will be restored. Or you can by a refurbished complete power board to save you some stress from www.shopjimmy.com

Note: There may be also some other causes for this symptom ,like a defective T con board ,or main board,but the bulged top capacitors are the most common cause for this issue.

If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you. Also, note that TV stores a lot of current, so wait a while before opening the TV back cover.

I hope this helps.

Regards.

My sanyo dp 55441 wont come on
Try unplugging the TV, an hour later, now reset the TV back to Factory Settings. Now, the TV should be working properly now. Try a website like Ebay.com to buy a whole refurbish power supply board for the replacement.

Sanyo DP46861 won't turn on


With Sanyo DP series that is almost certainly a bad main board.

As of February 2013 I am not sure we have worked on this particular model yet, though, so I do not rule out a regular problem with capacitors in the power board.

We have extensive experience with other Sanyo main boards as can be witnessed at our site and if you have no other option you can send the main board for examination through our site.

I can't guarantee how fast we'll be able to deal with it unless we already have announved that we repair those boards...every new one is always slower than the ones on which we already have accumulated know-how and experience.

(follow the link for Sanyo DP series at the front page and search for your model; contact us if it's not listed there)

Sanyo DP 42849 42'' lcd tv no audio no video


Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

3 YEAR OLD SANYO DP 32746. SHUT ITSELF OFF, CAN NOT TURN BACK ON


If you leave the tv unplugged for 2 days (atleast) then plug it back in and try to turn it on and if it comes on its the power supply board. If it comes back on it will probably shut off between 30min to 4hrs and you would have to unplug it for 2 days again. All the power needs to drain out of the tv. If thats the case take the back pannel off and check the part number out on the internet. Not hard to do becarefull touching things the power supply does store a little bit or shock in it. Good Luck.
