I got an RCA RD2826A it came with a universal charger (and it was on a higher voltage when I accidently plugged it in, everything went black and hasn't turned on since. I am hoping there'is a chip or something besides the hard drive that burns up. Can anyone help me? It's brand new . Can it be fixed?

Re: On the fritz
Everthing can be fixed, the issue is that if it can be fixed at a reasonable price.
You are right, when the wrong voltage is applied to this family of Lyra mp3 players, there are a couple of integrated circuits in the battery charging circuitry that are burned out. They do need to be replaced.
You can look for local qualified repair centers for a quote to repair it.
If you want a diagnostics/repair service for it, at lower fee, you can contact the Ebay seller with ID Great_items_2004
a 6ya expert can help you resolve that issue over the phone in a minute or two.
best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).
click here to download the app (for users in the US for now) and get all the help you need. goodluck!

An incompatible charger could be doing this, as could a failed battery charging circuit in the notebook. It is also possible that the battery is no longer capable of accepting a charge. The universal charger must be able to provide the same voltage as the original charger and have an equal or higher rating for wattage or current.
Polarity - If the plug fits, this is PROBABLY ok, but the negative/positive must be the same as the original
Voltage - The voltage output should be the same as the original, which will be a few volts higher than the battery. If the voltage output is the same or less than the battery, it won't work. If the voltage is too much higher than the original, it might fry the battery and the charger.
Current rating - If the current rating of the replacement charger is less than the original, it might fry the charger. If it is much higher than the original, it MIGHT fry the battery. You can probably go +/- 20%
Please check the technical specifications of your computer charger and see that your universal charger fulfills the same. Generally it is found that the universal charge may supply the required voltage but may not provide the required amperage. That is the reason most of the electronic companies insist on their chargers. If your charger is not working please get one from the company rather than using the universal charger and the spoiling your computer.
Universal chargers are OK for some of the electronic devices which do not require higher currents.
You do not have to be worried about the wattage. Wattage (in the case of chargers) is the capacity a charger can provide. So higer the wattage better it is. However, higher the wattage higher the price usually. Voltage has to match. But the most important thing to look for when you buy a universal adapter is the polarity. Take care to match the polarity. Polarity will be represented by a small line encircled by a circle with + AND - . If you look at it carefully you will understand that it is trying to tell you what polarity is the inner lead and the outer lead. You will see this marking on the charger and also on your laptop close to the DC in. (Usually the inside lead is positive and the outside lead is negative) However some manufacturers reverse this. (I have no idea why they do it though I think some kind of regulatory body should make a standard to avoid unsuspecting users from frying their devices). If your voltage and polarity is matching you are good to go with 65 watts or above. If this holds good, don't worry about any listings.
- Your laptop should have an indicator that tells you that its battery is being charged (when plug-in to charger) or discharged (when running of battery). - The universal adapter will have several voltage settings: make sure you have selected the correct voltage (DO NOT USE VOLTAGE SETTING HIGHER THAN REQUIRED OR YOU WILL DESTROY YOUR BATTERY REGULATOR!)
Assuming you didn't get the PC board mounted inside the top of the tiller assembly wet, or the power controller located under the shroud, then you likely either have one or two of the batteries that are bad, or a bad charger. You will need a voltage tester that you can pick up cheap for about $6.00. Set to the DV voltage setting in the 50-100 volt scale. Remove the seat and the shroud and test the voltage at each battery. If good, they should read about 12.25 volts or more, not higher than 14. If one is normal and the other lower, say 10 Volts, that low one is bad, but you should probably replace both with fresh gel batteries, fully charge before using. If both batteries are about 12 VDC, then plug in the charger to the chair as usual, and take another voltage test on each battery. The voltage should read higher now that the charger is on. If they aren't, then your charger has no output. Some chargers you can test output voltage on without them plugged in by testing across the two horizontal pins on the 3-pin connector that you plug into the chair. The output voltage should be about 26 volts. If it is 24 or less, you need a new charger. Good luck.
You can use any adaptor that supply 12V or more. If you have at least 800ma of current, and 12V or higher it will do the job. Higher voltage rating will charged it much quicker but you have to watch it.
next to the jack on the camcorder it should have a diagram that shows polarity (a + and - sign) for the plug, the tip should be one sign and barrel or outside of the plug should show the other polarity. you have to have your plug with the correct polarity, and you have to have the correct voltage( it should say 9v or 12v or something like that) and the supply you use should be as high or higher of a current rateing as recommended in your users manual or printed on the supple that came with it.
