What seems be the problem of my aiwa 14 inch tv, thus it has something to do with tv system ic?

Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" or "Magazine" will make surf easy. Surf the site with patience. Pull up older posts.
Do a search by type in the brand name of your device at its search box.

I usually play video games on the rca 14 inch true flat tv but my remote broke that they gave me so i cant go to input to play video games. Do i need a new remote for that or can you do it a diffrent way...

Unless the set has front panel menu buttons and the on-screen menu allows you to select the source, the answer is "no, you can't switch without the remote". If the original remote is really broken, you may be able to use an RCA-brand universal replacement that has an "input" or "source" button. Unless the original is physically damaged, before you toss it check the battery contacts inside. They sometimes get loose from handling the remote a lot and don't make good connections. Also make sure the new batteries are fresh and facing the right way.

My tv cycles off and on ,by itself.

Try a power drain to see if can keep the TV on consistently:
1. Unplug the product's power cable so the device is not grounded to the house. 2. Press and HOLD the product's own power button for 1 minute to drain the capacitors. 3. Plug the product back into a wall outlet and try to turn it on.
Note: This procedure works with battery operated devices as well so remove the batteries and hold down it's power button.  Electricity can remain in capacitors and on circuit boards enough to prevent normal functionality. By clearing the residue electricity, your product will have a fresh start and many times this will resolve a buggy or non-responsive device that appears to be dead.
If the TV continues to turn off and on after this, it would appear that there is an issue with the TV's power supply as it may be on it's last legs.

TV turns off

Sounds like it could be overheating. Verify that the vents are not covered and there is plenty of space around the TV. Make sure there is nothing sitting on top of it.

Go into your menu. Sounds like your Parental lock might be "on". You should be able to solve your problem in the menu. Keever

Zenith A32B43W color problem

Classic symptoms! Most of the last TV's made by the old, original Zenith company (Rauland division) had bad picture tubes even when new. This probably had something to do with their going out of business and being taken over by a much better Korean company (LG Electronics AKA Goldstar). Another lovely thing they did before biting the big one was to only sell a complete chassis as a repair part. If your TV is older and has a small white paper tag inside somewhere on the picture tube (usually near the larger brand and type number label) with the code "EIA 1101" on it, discard it. I have NEVER seen one of these work correctly! If the CRT is made by someone else, there may be slight hope. Even if the TV is not very old, if it was really made by Zenith, and not LG, the possibility of repair is slim simply because of the change of ownership. I was sad to see Zenith die such a horrible death. They used to be fairly good, but somehow never made the transition to color TV. After 1954 they were essentially moribund.
