Changed battery now radio doesn't display song or artists name. How do I fix this?

Once you disconnect the battery everything that is in your memories goes "poof" it will take a little time for all of your stations to come back. If I'm not mistaken you still have to set those manually. Radio is mostly satellite that's why you get song names etc. So drive let the computers collect data and before to long you'll get to see this names come up again. Hope this helps.

    • check that the program card is correctly installed.

Samsung TV LN40B500P3f - No Picture ; just audio Hello, Our Samsung LN40B500P3f TV audio display is black; audio works fine. If I turn TV off and then back on the picture does display for a few secon

The set will need to be properly diagnosed to narrow down the problem. You could be looking at a bad inverter, bad CCFL lamp, fault in power supply or main board.

I rebooted my PC and now screen is darker and my colors are off

Check the contrast (darkness/lightness) on your Samsung LCD. There's a menu button on the monitor, press that and select contrast setting from the Menu.

My Samsung YP-T9 MP3 Player wont turn on!!

I think holding down menu and the record button at the same time should fix it. I read the best solution and it just turned on. I was having the same problem, mine would not turn on either but just try pressing and holding down the record and menu button for about 5 seconds.

When I turn my camera on, the lcd doesn't display. I can review an image though in the play mode. any ideas??

Rebel XT doesn’t have live view function. You cannot have picture on LCD when taking picture. If you can review the pictures and operate menu on LCD, your camera just fine.

Fault on my Transceiver


You posted your concern as generic with no specific brand or model. Flashing displays can mean a variety of things to different makes. Some of which are:
1. Low battery. Low memory battery;
2. Error in programming;
3. Error in firmware;
4. Fatal error in self-test/diagnosis;
5. Major component defect detected; and/or
6. Out of range/band.

In the same token, corrective measures can likewise be anything:
a. Recharge/replace battery;
b. Reprogram/reload program;
c. Update firmware/clone;
d. Run diagnostics using an external device (often a PC);
e. Determine which is at fault (finals, VCO, PLL, voltage regulator, replace);
f. Tune back to standard freq.

Most often (but not always), it can be also be corrected by doing a reset of the radio which can be:
i. Pressing FUNC (or some other button) while powering up;
ii. Pressing a recessed/hidden reset button;
iii. Placing a temporary jumper/shorting two (2) points (internally on the logic board);
iv. Remove battery/power (including internal if any);
v. Pressing a sequence of buttons to enter MENU/SETUP mode.

Hope that this be of some help/idea. Pls post back how things turned up or should you need additional information. Would appreciate also if you can specify brand/model/region.

Good luck and kind regards.

I had a problem with a Samsung 46 inch LCD and it had audio and dim light but no picture and found out that the logic board toward the top (inside tv) was bad and was no longer available and the only way to fix it was to get the entire display panel (the logic board came with it) It was not costwise to repair. Hope this helps.
