I have an RCA truflat TV - model # 27F650T - about 7 years old. We are suddenly getting the message "unusable signal". We can hear sound but no picture - We put in a DVD to make sure it wasn't the TV and we were able to watch a DVD. The cable is hooked up correctly and the TV is on the correct channel. This happened once about a month ago and after searching for answers on line, it said to uplug the TV and the cable box for 24 hours to reset the TV, which we did and it did work. However, this happened again and we tried the same thing but this time it did not work. We get sound, no picture and we are still able to watch DVD's. Any help would be greatly appreciated.

The problem sounds like a problem with a power supply or a power chip. These can be a cheap fix if you can find a cheap TV repair man, but expect to pay hundreds at a TV repair shop.

I can;t keep my DISH satillite to turn on. when I turn the tv on and hook up the cales i get unusable signal and blue screen

eeprom memory corrupted change it

we spoke to someone who has the same model, all better

Either get a priest to do an exorcism..... or it sounds like an internal issue.... likely a bad capacitor. if you are able to do some basic troubleshooting ... remove the back and look for any capacitors with rounded tops.

be sure to cycle thru the input selections-- either w/Remote (input button), or channel +/- on the panel. my truflat 26" hd set has side/front/video1 video2 inputs, yours may have more or less. also, be sure you've plugged into an INPUT set, not an OUTPUT set. Does sound work otherwise on this set? If not, maybe interal speakers (menu setting) is set to off/not checked.

And on your PS3--goto the settings menu, sound outputs, make sure you select A/V connector and analog sound. The ps3 cable can become sloppy too, wiggle/check/reseat or try another cabe (usually video is touchy more than the sound though)

If you KNOW you've got the right input selected and the PS3 is setup properly, do you have another device with audio output to test on the TV? a notebook computer, walkman, cd player--anything that has rca outputs for sound--quick swap the cables to the new 'test' device-- if sound is OK with test device, either PS3 setting or cable is bad/wrong. if no sound from test device on TV either the tv is not using proper inputs, or is damaged, or the test device is not properly configured. If you have another input receiving device to test the ps3 output sound, like the LINE INPUT on a notebook computer, or a boombox with Aux inputs, test the PS3 sound output too.

Yea I had that problem one day as well.. all you got to do is go into the menu settings and check the box for the Int speakers... that should do it

Read the suggestion of unplugging the TV for at least 4 hours to re-set to factory specs and that took care of it!

you can check only for the fuse if it is busted or not
locate the fuse. check if it open using a tester.......

if you have no experience yet on electronic servicing then you can fix it.

Sounds like you turner is shot
