My ultra hdtv 40-500 works for 5 mins then dish logo flashes and no visual


Hello, if the "Dish logo" flashes then no picture, it sounds like a Dish receiver problem not a tv set issue. Try hooking up a dvd player to it and see if it works. If it does, try resetting your Dish receiver. Thanks....Terry

My Samsung LNT3253H LCD TV has suddenly started changing its own settings (e.g. picture mode keeps switching to ''dynamic'' and the ''light effect'' keeps setting itself to ''always on''). Any thoughts on...


Hi,

Its in "Shop Mode".

Change your source to TV (analogue), now press menu>find "Plug and Play" and select it and runs through the setup and selct "Home" prompted and not "Shop".

That should sort its out, when its in shop mode its doesn't matter how many times you make changes, when you power it off it will go back to the original shop settings, this feature was built in to allow shops the have all show TV's to run at optimal settings and if a customer played about with the settings it would matter as they are reset again when the TV is switched off and the store staff don't have to go around resetting all the TV's at the end of the day.

Thanks

Audiosonic KMCTH68 Keeps turning itself off after 2 mins


CHEAP TV VIDEO REPAIRS
Can't be 100% sure but the most likely cause of the problem is bad solder connections in the switch mode power supply or on the vertical output IC, or anywhere on the main or picture tube circuit boards, due to age and switching on and off TV's develop bad solder connections when cold the connection is made and when it warms up due to heat expansion the connection breaks, you will need to be handy with a soldering iron, and discharge all power supplies with something like a 100 Watt globe before soldering or you may blow things up and do really serious damage, and be warned TV 's have very high voltages 360 volts DC in the SMPS primary and over 20,000 volts to the picture tube, so be careful.

My Epson R1800 keeps resetting itself


You have done all the usuall checks, but you may have a usb power problem, try the printer without any other usb peripheral in and see if it stays connected. If not, then the usb connection or workings in the printer may be faulty and keeps disconecting, hence the bing bong as it re connects to windows. You may have faulty hardware, leave the printer disconnected from usb and mains for 15 mins or so then try again.
