Troubleshooting samsung tv

I wouldn't replace a power board before measuring to see if the voltages are there and correct....

try clearing your cache partition, you can get to the android recovery with your buttons.
1. Turn tablet off. You may need to use two hands in this process to press and hold buttons properly.


2. Turn on the tablet with power button, wait a full 2 seconds from the time the tablet starts showing the red Motorola logo, then press and hold the down Volume key. (you should not hold down the power button after it turns on and logo appears)


3. "Android Recovery" will appear on top of screen if timing is done correctly. Release volume button. (if you continue to press volume down at that message, the message will cycle through "RSD, Fastboot, and back to Android Recovery. Make sure message states Android Recovery before you go to next step). If stuck at a RSD protocol or Fast boot screen, reboot the tablet by holding power button then pressing the volume up).


4. While screen states "Android Recovery", Press volume up button, the screen will say "Entering Android recovery mode" and a few seconds later an Android robot graphic will appear alone on the screen. Release buttons.


5. Hold down power button and then press the volume up key together to see the Android Recovery screen menu selections.


6. Use the volume buttons to move up and down through selection in this menu.


7. Using the volume down button, scroll down to "Wipe data/factory reset"


8. Tap Power hard key to select option.


9. Scroll down to select "Yes, delete all user data".


10. Tap the power button to select. Wiping and formatting data will take a few minutes.


11. You will return back to the Android recovery screen menu.


12. Tap the Power button to "Reboot system now" which will power-cycle tablet and eventually power back on to the Initial Set-up / Welcome screen present when you first turned on your tablet.

Check the buttons on the tv itself and make sure the volume up button is not stuck. Samsung.com is not showing a tv with that model number. There may be a software update for that tv so check the model number again and check their site.

The fault is with its main board itself. Troubleshooting to this board is not an easy work to a user can do. It will be best to contact any service technician. google.com/+GopakumarGopalan

Hello
If volume of the TV doesn't rise up as its volume is increased with remote control handset, and the volume indication bar runs full, the fault is with the TV itself. Either its speaker may be damaged or its audio output section has some trouble with it. Check its speaker first for damage. Connect an other good speaker in place, and you can check it by yourself. If the speaker is good, the audio output ciruit should be traced for fault.
Here you haven't given any details about your TV. Its Model number Brand Name etc: Eventhough you have given all these details to me, you must have a sound knoledge in electronics, and must have all tools with you to go forward with its inside circuit. OK.

Yes you can, but be sure to put down a thick blanket and put the face down so the screen will not be scratched. Lying one down will not affect the picture whatsoever when you set it back up

damaged lcd screen are not repaireable but are replacable. mostly expensive depending on its size. handling, shipping or transporting units with lcd such as plasma tvs should be given extra care.

Good Day;

The TV's front panel may be bad, manual buttons. TEMPT FIX; remove speaker, cloth covered, cover, disconnect cables. TV will work but only with remote.

Good Luck!

hope this link should help

Sounds like you have a jammed / shorted out button on the control panel... Try un-plugging the tv, and then unplug the "button panel" on the front of the tv...see if you can turn the tv on with the remote. Sometimes if one of the buttons gets shorted, it will "lock" the processor from doing ANYTHING else, as it thinks you are holding down the defective button. If this works, simply have the defective switch or control panel replaced, or just leave it unplugged and use the remote only! Hope this helps!
