When you switch the TV on with the remote or on the TV. The TV comes on for a few seconds or minutes then switches itself off. The red light on the front of the TV flashes. Please HELP. Thanks Mary.

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.
Blinking codes details to many popular brand TVs are given. Surf the site with patience.
If blinks continue without any pause, the main board is faulty.

Rca tv is on it has sound but da screen is blank

You have posted your problem in standard televisions; haven't any model number at all, and posted a picture of a flat panel TV. Actually, what type of TV you have? Fault with flat panel TVs and standard picture tube type TVs are entirely different. Please provide exact model number or type of television. If you can give me some more details about the problem you faces with your TV, will be more helpful.

How do I switch to video input for a dvd player on the sanyo ds25390?

Look for buttons like input, or SOURCE, those typically can be found on the tv, and the remote. Be sure to have the DVD on, or many TVs time out and go to sleep. Some TVs take a LOOOONG time to connect.

The TV turn off on stand by by itself often when it is cold, later the periodicity is getting longer. The colors little bit changed to worm color

During switch on your TV for the first time, when it is cold, you just listen for any 'ishhh' sound comes from the back side of your TV. You can check this by keep your ears close to the top back side of your TV. If it is there, there will be a fouling smell also. It will smell like Ozone, actually it is. If so, your TVs picture tube conecting socket, or EHT boot may be faulty.
Normally Sony TVs will not be to this fault, but a rare of them have. That is on cold climate,, especially when humidity in the atmosphere is high, this fault will be more. If you hear the above said sound, and feels the smell as I described above, you just open the TVs back cover. Keep the mains wire out of wall socket and do this. After opening the TV, just switch it on. Check out from where the sound comes from, whether it is from the picture tube base board or from the EHT cap fitted on the top side of your TVs picture tube.
If the sound comes from the above said anode cap, there will occur an arcing too, which you can see it in dark. If so the anode cap must be replaced. It is an expert job to do. Because before removing the anode cap along with its clip, the electical charge accumulated there must be discharged to a stromg negative point on the chasis, otherwise you will get a high voltage shock from it. Even though the TV is switched off, and after removing the mains chord from wall socket, the charge said above will retain there for hours, and it is dangerous to touch. That is why I said that it is an expert job to do.
If the sound comes from the picture tube base card, it will be due to the fault of CRT base socket, which is diretly soldered on it. It can be desoldered out from it, and can be replaced with a similar one, and can be bought from electronic spare part shops.
98% of Sony TVs are equiped with special circuits inside it, which detect any fault, whether it is minor or major, and keep the TV shut down as a precauion against further damage to other components inside. In your case your TVs protection circuit, detects some short or some fault, and shuts your TV as soon as you switch it on, and allows only to work after the fault it detected has over.
If this is not the fault, your TVs front panel standby light will give you indications about the fault inside your TV through chims. You just count keenly and patiently for three or more times, that how many blinks you see before it shut down, and report it to me through Fixya. The count must be exact. it will help me to come over to which section in your TV the fault occurs. Ok

Remote doesn't switch to game mode

It won't let you switch to video/game mode?
If it's a universal remote, it may just be that the button is actually called TV/VCR instead of AV or input.
If it's the actual remote for the TV, then perhaps the button itself is no longer working (usually from repeated pressing or excessive pressure/twisting). Either that, or the digital circuit that controls the switch between inputs is no longer working.
Try accessing your TV's menu with the controls along the front or on the remote. Most TVs will let you switch through those menus.

How to replace fuse on sanyo tv DS 24424

Actually, when a fuse blows, most of the time there is something that went bad and is causing the fuse to blow. Some TVs don't use the typical glass fuses. Instead the might use a surface mount soldered component. These components are usually labeled with the letter F for fuse. Example would be F1 or F2. They are usually found near the power cord or near the power supply. Hope this helps...

Tvs are wired differently these days. Your old Zenith for example probably had a selector switch that allowed you to change from internal or external speakers, bandpassing the audio from the internal amplifier to the audio out connectors. Your Sharp on the other hand may be controlled by customer menu to perform the same function as the external switch. Go into the menu and sub-menu of the audio and see if it gives you any choices for selecting internal or external speakers... If it doesn't it probably will not bandpass the already amplified signal, which means if you want to listen to your Tv on those external speakers you'll first have to pass the audio sample through an amplifier.
Hope this helps.

Need help trying to figure out what's wrong.

Apologies up-front, because I know this isn't the kind of advice you were asking for. I'm a great fan of people having a go at fixing things for themselves, and wouldn't normally push the safety whinge much further than "don't forget to turn it off before you start poking around inside". BUT TVs ARE DIFFERENT. There's bits of a TV that can give you a fatal shock long, long after you've switched them off. If you're really as TV illiterate as you say you are, my advice would be to leave the thing alone, and live to mend something else another day. Sorry to be such a pain - I'm a professional Electrical Engineer and have worked with all manner of dangerous machinery in my time - but opening up TVs still gives me the creeps. A.
