SOURCE: PS3 been working fine over

TV Connectivity
The issue of connectivity between the PS3 and the display is very complex and depends on the type of TV (Analog, Digital or HD Ready), the maker of TV (until recently, only Toshiba TVs have component AV connections as standard in Europe, most other Euro TV sets use SCART which can not carry an HD signal) and specification of TV (the very latest HD Ready TV sets have wider connectivity options than earlier HD "capable" TVs from the same manufacturer which may have lacked HDMI), and finally the configuration of the PS3 model purchased.

SOURCE: I have DMTECH TV/DVD LT20X-1U23DMI ....

Assuming that by "working outlet" you mean something else like a lamp will work, then, the first thing is to make sure its the TV and not the remote control. If the power switch on the TV will power the unit, the the remote probably has dead batteries.

Assuming it wont respond to either the power swtich on the TV, or the remote, then look on the back of the set for a reset button and push it. Some units have a sort of circut breaker. It may be best to do this with the unit unplugged.

If none of this works, then try moving the cord around. If the TV will power up depending on the cord position, then you have a bad power cord, which is a pretty easy repair.

If none of this works, then the chances are that you don't have a Do it yourself kind of problem

SOURCE: Westinghouse SK26H240S - Sound works but no picture?

There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

The sound on my symphonic 19" personal television can not be heard but the picture is fine. How do I get sound back on my tv without a remote control?

The earphone jack may be damaged. This takes the audio from the set and provides either a path to the speaker or when plugged in to the earphones. Try the earphones - if they work, the jack may be at fault. If the remote has muted the sound, turning the TV off then back on should reset the mute.

When turn on tv with remote and without remote it

I have the same tv. Something to remember is that the picture is lamp powered. It takes about 30 seconds to power on and takes about a minute to fully power off. I had issues when trying to turn on the TV, accidentally double tapping the button, which would turn it back off. I'd do the same when trying to turn off the tv.

If you are sure this isn't the issue and the lamp light is still on once the tv turns off, most likely your bulb is burnig out. You can find replacement bulbs on the internet. They are fairly easy to install yourself, so you shouldn't have to have the tv serviced.

If the bulb seems fine, your tv could possibly be overheating. In that case, make sure the vents are cleared as the tv gets pretty hot.

Sony FD Trinition WEGA KV-32fs120 32" (no picture)

If the standby light is blinking 5 times then repeating, it is likely a problem in your picture tube or related circuitry. Other possibilities include the "Jungle" IC which takes care of the video, chroma and deflection processes and is a bear to replace. Either way, it could be an expensive repair.
