Question about Denon DVD-757 DVD Player
I hate to say it, but if the unit won't power on at all, regardless of the wall socket it is plugged into, that it is a general failure of the switchmode power supply, which, unless you are 'tech. savvy' or have relevant electronics experience with PSUs, will require repair by an authorised service technician in a fully equipped workshop - one which specialises in Denon product sales and service.
However, you say you have 'the lid off' (I love that description) and plugged into different outlets. While you have the top cover off, and unit unplugged from the wall, you can examine (at least visually) all the electrolytic capacitors in the power supply; look for any bulging, crooked or leaky ones. These may be the primary cause of the failure in the PSU and since these are inexpensive components they can easily be replaced (they are not surface-mounted on the copper side of the board), either by yourself or by a workshop if you have no electronics experience.
This unit may be repairable, but at a cost. Get a quote from a service centre on the likely cost(s) to fix this unit so that you can make a firm decision on that basis. If you do go this route, insist on a technician's report from the workshop after repair and a written guarantee on the work done. This is up to you.
Denon is a quality brand and they have made many great audio/visual products over the last 20 years or so. Worth pursuing if you really want it repaired properly, irrespective of the age of the appliance.
