basically it is input issue Brent, you may want to turn off and on your tv after 4-5 minutes, if same thing press on your tv remote INPUT, SOURCE or TV/VIDEO and you should have input lists on your tv screen. Choose one by one until you got a picture. You can also check this out.

is it the picture or the back light ? does the screen go white or darken. ?

most shops and store will have them. even ebay.

are you getting a stand by light ? dose it flash when you try to turn on tv. count how meany flases it make before it goes to soled red again.

there is a dtv board inside. you may need to change the board or it may just not be connecting properly clean the connector and see if it works then they can come lose when tv is move about.

have you checked the capacitors check them on the power board look for a none flat top if any look like the tops have lifted up and gone rounded change them. also check the sound board for the same.

if you turn off at wall. leave for 3 min put power on and hold down volume up and down wile pressing the power button see if that works.

sounds like it is over heating. in side the tv there is 2 square box cannot remember the colour but they are yellow or blue near to a heat sink chip. if you change them it may just be that fault. Bush tv's suffer from this problem.

try the board number its self there are a lot of tv's with the same power board.. use the board number.

take it to a service center

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.

it will take a bit of time to explain my solution but if go to tesco tech support you can find a video of the same solution on youtube if that does not work you my have to replace the sensor on the TV

it sounds like some of the capacitors have blown TV repair company will charge you a lot for this but its a cheep fix if you like to have a go. Go to youtubb and in the search type, how to replace capacitors

Or www.digikey.com, just make sure to use caps with low ESR, 105c, high ripple current and long life rating such as PANASONIC FM or FC series.

Sounds like maybe power supply, but I would check with flashlight 2 in from screen when the green light comes on to see if you have a picture, if so then you have a bad inverter board, if not then power supply problems. You can look for bad or bulged caps in PS
