    The same thing happened to mine - one hour it was working and I was watching a movie, and when I went back to turn it on and finish the movie, it wouldn't do anything.

    The TV was working just fine, we were watching a show and I went to turn the volume down and the remote didn't work, I got up to lower the volume manually and it still didn't do anything. Kinda annoyed! Now we unplugged it and plugged it back in and nothing works, won't turn on at all!

I have the same problem with my MWC20T6A (from Walmart), and I keep blowing fuses. I read somewhere that it's in the motherboard which is about $150 to fix. I'll never by a combo again.

check one by one :
1. power in outlet by plugging an other equipment in the outlet used for your TV,
if ok try #2
#2: carefully open the back and check the power cable with ohmmeter
if ok , try #3
#3. check for the fuse ,
if ok , call a technician because there is some fault which you can't do by yourself

My Samsung LCD has no picture (screen is black) and the power repeatedly turns on and off. The red light on the power button continues to turn on and off. Can you help? The TV is only 3 years old.


open back cover check 5v filter capacitor on powersupply board that is either 1000uf or 2000uf
do you see any bulging capacitor? replace with top quality capacitor.

Green light blinks.. wont turn on.... standby pwer appears normal.. ihvt and hor output check fine


*This was posted in another thread as a solution to your problem, it would seem that this procedure is for the TV savvy, and I would not recommend that you do this procedure, and that you bring it to a TV repair shop. Or if the TV is still under warranty that you turn it in. But if you are planning on following these instructions I wish you luck, and make sure you follow them to the word so you don't mess up your TV even more.

Found that the thermistor/temp measuring device is suspect, noresistance across legs. There is a label there that says F701 seeservice manual
http://www.goodmans.net/get_item_th-tf117c_thermal-fuse-117-degrees-celsius.htm
I went here for a tech manual for the Panasonic
tv.
http://www.ManualsParadise.com
then ordered
Manufacturer: Panasonic
Part Description: FUSE
Part Number: LSJA0411-1
from
PartStore.com
it was mounted to the case that holds the lamp. had to remove the backpanel, etc. Also think I had to splice in the fuse or something. was awhile ago.

i purchased a NTE8115 from my electronics supplier, closest I could find.
Radio shack also has them.

remove the back cover and measure for continuity across the thermal fuse
above the lamp housing.
if open jump it wth a 5 amp fuse, be sure to close the safety switch with
the small blue lever then try to power on.
If comes on ok you will need to replace the entire ballast assembly to get
that fuse.
Panasonic does not have a part number for just the fuse on the PT40LC
series.
It is possible to cut off the fuse and replace with another but dont solder

MY SCREEN IS DARK OR BLANK EVERYTHING ELSE WORKS GOOD JUST NO PIC


Hello fixedopsmike,

There is a fuse in the TV set, if you would like to check and see if it has blown, here is a way you can do it:

1) Unplug the TV's power cord from the wall

2) Take the back off of the TV by removing the screws and slowly removing the back panel.

3) Look for a component that looks like a glass tube with metallic caps on each of the ends, this will be the fuse.

4) Visually inspect the fuse to see if it shows signs of being open (Blown) These signs are burn marks inside of the glass tube, an open conductor (wire) inside of the glass tube, or no visible wire inside of the tube.

5) using a multimeter set to resistance (R x 1) test the fuse for continuity (remove and change the fuse if found to be defective)

6) If the fuse is not bad, reinstall the fuse if removed, put the rear cover back on.

Now at this point we have determined if the problem is a fuse being blown or not, if you replace the fuse and the TV works great the problem is solved, if you replace the fuse and it blows again, or if the fuse was ok to begin with, then you have a problem that will require some knowledge of electronics pass the basics to continue on. At this point I would suggest that you call a qualified TV repair technician to troubleshoot and repair the TV in question.

I hope this helps,

Thank you,

Wont turn on


OK, it looks like a power supply problem. The click you are hearing might be the shutdown relay connected to the overcurrent circuit. This might be indicating a problem in the Hv section of the TV. To get the tape out you can restore the power supply or what you could do is to try to access the drive motor and find the load and unload gear and try to turn it to take the tape out, this has worked in the past at my shop. If you have no experience in electronics I would suggest you not trying to repair this set because of the danger involved. Take it to a qualified repair shop.

My Television won't turn on


The dust had to be wayyyy excessive to any damage to the tv,it does not help but it wont hurt onless there was also water involved,if you have no indication of power (no lights ,no clicks)it might only be a fuse,if a drill or something similar was plugged in the same outlet as the tv that might have created the problem,if you are familiar with tv service or someone you know can safely remove the back and check the fuse is might be worth the effort.Just to make sure plug a lamp in the same outlet as the tv just to see if you have power coming out of it,the people working might have killed the circuit.Let Us know how it goes or if you need more information.
