Check the fans, when the set is ON. All of it should work. If not, contact the authorized service centre for Samsung. Do not use the TV; with non Woking cooling fans. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" will make surf easy. Surf the site with patience. Pull up older posts there.

Need to program my Samsung universal remote to my Panasonic TH-42PX20 tv but dont have instructions or codes. Help please

Your Samsung universal remote probably has a code search feature you can use to find a code for your Panasonic TV. If you search through all codes stored in the remote without success, you may have to use another universal remote to get results.

Overheating of Partition in a side-by-side

pull off the bottom front kick panel and check the condenser coil to see if it's filled with dust,also pull out the machine and remove the back bottom panel and make sure the condenser fan motor is running and clean out any dust back there,if the coil is clogged with dust or the condenser fan motor isn't working is what could make that strip hot.

No picture power button blinks

We cleaned the dust off the fans and TV now works fine. Hardest part was getting the TV down and the back off to get to them. Thanks.

Shut off blinks 11 times

I have recently solved the same problem with my panasonic that was just 2years 2months old. I took off the back of the tv and brush off the dust as there was too much dust clogging the vents and fans at the back. The tv is now as good as new. Hope your luck is as good as mine. by the way i was having 11 blinks as well.
