Check the speaker/s first. If found OK; check and replace the damaged component/s at its audio output section circuit board. If needy, replace this board as card basis.

Hi Chance, FYI. https://www.google.lk/url?sa=t&rct=j&q=&esrc=s&source=web&cd=8&cad=rja&ved=0CGoQFjAH&url=http%3A%2F%2Fwww.helpowl.com%2Fp%2FSharp%2FLC-32SB28UT%2FResearch%2F76033%3Fsearch%3Dsharp%252032%2520lc32sb28ut&ei=ZpLPUtC4LOn6iQe51YEo&usg=AFQjCNFrAqFZXE71Qr5FVcnpEbhCTD4igA&sig2=zJU5OMykglEmwPFDvi89ng&bvm=bv.59026428,d.aGc

I see so many here with no sound/nopicture issues:ISSUES: 1. IF sound main fuse/s are good.2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.4. Be safe and if you do not know what you are doing don't open the set.Answers to issues:1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.3. Trouble shooting consists of the above and then at some point you have to buyand try a board to see if it fixes it or not.4. Safety first--no TV set is worth getting injured or even killed over.If set is opened at least look for puffed up and bad caps like in thisphoto.

PAL-M is 525 line 29.97 frames per sec, PAL-N is 625 line 50 frames per sec. Most countries (e.g. UK) use PAL B/G/D/K/I which is 625 line 25 frames per sec. PAl-M is used in Brazil, PAL-N is used in Uraguay and Paraguay. Most modern TVs will handle both PAL and NTSC as long as the RGB input is used (via scart or HDMI).

Hello If your Roku 3 player is not connecting to WiFi, it is possible that the WiFi signal from the router is out of range. In order to strengthen the signal, move the router and Roku 3 so that there are fewer objects and walls between them. For any help or support just visit us: www Roku Com Link

When you say WD box, do you mean a Western Digital Hard Disk Drive? If so, get a Solid State Drive (SSD), and connect it via USB3. The HDD or the USB connection is not fast enough to keep up with the required speed of the video. If you mean something else, please add details.

Check the high voltage circuit on the board that has the 120 volts input. The high voltage should be close to 400 volts - nothing less than 390 volts. The capacitor is failing to hold the voltage and needs to be replaced.

un plug tv and try to force on by pressing vol_ and input button from tv then plug back in see if tv comes on .

Look for it at its bottom side [stand]
