The issues that you will have when DOWNGRADING is the availibility of drivers that can run the newer hardware. Hardware capability has exceeded the ability of XP. Sometimes the boys at HP can direct you to drivers that will work. I strongly recommend against downgrading. If you have Vista, you will like Windows 7 much better, it quits asking for authorization on everything.

i'm not sure if this will work at switch on press and hold F11

I don't know which Keychain Digital frame you have but they all only hold Jpg files, some will hold a bmp file as well. How large is the file you are trying to download? They can hold 4 to 8 Megabytes of memory. The picture size needs to be 128x128 or less. I wish I could help you more!

you can reload the adapter driver or go to dell support

Unless you're a laptop tech it's not advised for you to do.
The motherboard must be removed the old jack unsoldered and the new one soldered in it's place
Not for the faint of heart

Check the power supply board for defective capacitors. Visually inspect the top for any signs of bulging. Replace them with the same rating - voltage and capacitance.

You can update the graphics card's drive. If it's no use, need to check the graphics card is bad

Video Cable

You have external speakers plugged in and it still doesn't work? This means the sound board on your TV has failed... it is repairable but expensive. Not worth it in my opinion on this size of TV.

IF you are looking for a local repair guy, please get me your zipcode so that I can look up the directory and get you the list of techs in your area.

Model? see some of my Dell TV albums.
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. If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on: Please see my basic troubleshooting guide here: http://www.fixya.com/support/r5093881-lcd_flat_panel_tv_troubleshooting_guide Failed TV and Monitors: http://s807.photobucket.com/home/budm/allalbums http://en.wikipedia.org/wiki/Capacitor_plague Parts: www.shopjimmy.com Capacitors kit: http://lcdalternatives.auctivacommerce.com/Default.aspx he can make you a set of caps. Please post back what you find.

You may have a bad inverter.

The tv overheats and a connection inside the tv breaks. You will have to open the back of the tv, clean very gently but thoroughly everything in sight and reseat every single connector.
