Question about Sanyo DS27800 27" TV

1 Answer

TV won't turn on

Yes, it is plugged in. :-) I try to turn on the tv and it makes a staticy sound for approx 10 secs then shuts off. No picture is visible and no other sound is audible during this time. I'm just trying to find out if this is a simple repair or if it time move on. I was recently "downsized" at work and am trying to save money. Thank you in advance.

After tv is on for approx 20-30 mins it starts to make a loud high pitched squeal or whine. once turned off for approx 10-15 mins can turn it back on for another 20-30 mins before squeal will return....

Sounds like a problem I had with a Polaroid t.v. Take the cover off the back and look for capactors that are buldging on the top. The top should be slightly concave. If they are convex at all, you can buy new one at Radio Shack and replace them for under $5.00

Turn power on, approx. 30 sec later it the power

It varies as to what is actually making the TV shut down. Shorting the connectors on the A.C. plug have nothing to do with it turning back on. Its just the fact you are unpugging it for a few moments.

TV turns itself off after a few seconds, no picture at all

As far as fixing goes, you might as well get a new TV... Unless its a LARGE EXPENSIVE HOLY $%^# TV, It will cost more to fix, than to just buy a new one, unless its under warranty, which being an older model as that (or so im reading) It may not be covered.

Try unplugging the TV, and while unplugged, hold down the power button for a full minute (yes, with the plug NOT in the wall) after a minute, plug it back in, and try. Its a hard reset. If it still does not work, and you've tried different outlets, It's probably a repair issue, and you'll need to get someone to fix it, or just junk it :-/
