Check for blown fuse inside if thats no then you need to trouble shoot the power supply

Hello
The possibilities for this fault are many. The first one is the damaged speaker. Just place your ears very close to the speaker side of the TV and switch it ON by its main power ON/OFF switch, and listen whether there is any "thumb" sound can be heard from the speaker. If there is; the speaker is OK and audio output section circuits in your TV has the trouble. The output IC and it surround components should be checked. As the set was working with an other audio system, before you buy it, the audio filter section inside the TV is alright. If 'Mute" function is ON, there will be no sound. In your TV, this function may be ON, becuse the party whom you bought this set was using its audio out to feed his amplifier. Normally, thsy will activate the MUTE of the TV, to make it silent. Ask them whether they ahve done it. If so, you have to set the MUTE of OFF. In most Sylvania sets, this can't be done without a remote. OK.

You probably have a shorted horizontal out put transistor and your TV is going into high voltage shutdown mode. The horizontal is located by the fly back on a metal heat sink.

Either you got lucky and just the few blew inside. Or worst case is the power inverter blew and will have to be replaced. You can test the inverter with a voltmeter. You can look at the glass bus fuse itself to see if it is bad or not.

just go to a technician to fix your tv. maybe the button defective

You should try Funai codes ( and possibly Symphonic) as these are probably the manufacturer of that set.

If you look carefully at teh line it should be red, green, and blue close together to appear like a white line. If this is the case, then the vertical circuit has failed. This is often poor solder connections at the vertical IC or a defective IC. Expect a parts cost in the $20 range for this repair.

Hello Princess mom, go to this link, select the type of remote you are trying to program and review the steps. http://www.google.com/search?q=how+to+program+a+tv+remote&hl=en&sourceid=gd&rlz=1D1DLUS_enUS358US358

Have you tryed Disc Cleaner and does it do it with all Disc tryed?

could be that either the dvd or the vcr are malfunctioning, usually it is the vcr that creates the problem. If you turn tv on and set vol to low see if you can hear the noise of the motor loading or trying to load,with out a tape inside. It may be a good idea to have a qualified tech repair it, these units are difficult to work on and further problems may come up if you are not familiar with the tv.

The VCR is not turning the TV power off. The tape is not playing. I'd guess maybe it needs a cleaning or a replacment.

If your vcr has a tape stuck ( or mechanism out of timing ) the set will turn itself off. Same for the DVD mechanism. It's usually the vcr. good luck

Problem solved. It was the video tapes themselves..they turned out to be from a special section for the visually impaired. I got used to it and watched them anyway. :-)

You can buy a cheap remote control anywhere. This TV uses the same codea as FUNAI tv's

On most models, there is a small hole on the side of the tray. If you straighten out a paper clip and stick one end into this hole and push, it should manually open the tray.

the vertical output ic is no good

run a head cleaner through it, a wet one is best. they normally come with the cleaning fluid and step by step instructions.
