Question about Sanyo Televison & Video

1 Answer

Sanyo tv won't turn on after a lightning strike.

I have a Sanyo DP52440 television that won't turn on after a lightning strike. I've tried other outlets, the capacitors on the power supply appear fine, and nothing seems particularly damaged (just by looking at it). When I hit the power button, the green light comes on for a few seconds, then turns off and remains off. After hitting the power button, I can hear a very faint, high-pitched sound I believe coming from the power supply. Is this something that replacing the power supply could fix? Or is it better to replace the tv? This tv belonged to a friend of mine, so I'm not sure the exact situation when the lightning struck (though it may have been plugged into a surge protector). Sorry for the lack of details, but I appreciate any insight.

Ask friend if broken when given to you. If not I would suspect the power supply is fubar..

    If separate part yes. On some sets the PS is part of another board and it is an all in one deal.

Your main boards are bad. They are no longer available, You have to have the chasis rebuilt. Mitsubishi is rebuilding these chasis. You have to pull it without any cut wires & ship to Georgia.

SOURCE: tv will not come on,

First off what is the exact model of the tv? Secondly do any lights come on at all? Do you have homeowners or renters insurance? then the surge would be covered under that and depending on size of the tv an equivalent size tv it would be worth it to put in a claim. Once I have more information I can assist you further.
Thank you,

If cable box converter has damaged, there is no question about the main board of your TV. It has been damaged. Before replacing it, you have to check the power supply board also. If the TV has been pluged to power supply, surely there will be fault to it also. We can't predict the exact fault occurs during a lightning, because Trillions of volts are passes nearby. You have connected the TV with cable connection and to the home power supply too.
Just replace the main board first. If it does not hel you, replace the power board too. I hereby send picture of both boards.

Where can I get a replacement screen for a sanyo dp52440 tv

The screen itself will cost just a little under what the TV costs. And finding a LCD is almost impossible. I suggest selling the parts inside to reclaim some cash for another TV.

Replace or have the powrer supply tested and eventually serviced.
Lightning strikes affect two types of boards in televisions - the power supply by means of entering through the AC line and main boards by means of entering from the external signal sources. External antennas are worst and can totally toast the main board whereas a signal entering through HDMI cable from another device is less likely to be affected by a power surge.
So naturally you start your quest with the power board , which is the usual suspect.

As of right now I do not believe we have an announced service for the power supply board of Sanyo LCD-24K50, but if you do not have any other options you can always try and send the power board for examination/repair through

Good luck!

Sanyo dp32648 possible lighting strike, whats needed to fix and a possible cost an can i repair myself?

It wont turn on? Well if it is damaged by lightning the only thing damaged would be the varactors on the power supply. They are there to absorb tremendous surge of electricity. The same way a surge protector works. A worse case scenario is the power supply board is fried up. Then being a non electronic technician you can purchase the whole board or order on line and install them yourself. If you brought it to a shop they will charged you for the labor and the board. Don't buy used boards on the internet because a lot of them are no good in my own experience. Get a new one for about a little over a hundred buck or so.
