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.

My aiwa tv has no power


what you can do is trouble shooting of the tv unit. first place to be check will be the powers supply section check weather the primary fuse get blown. if ok check the regulator and the bridge type diode which shorted. if all good, next will be the horizontal output transistor or an open resistance going to the b+ of the flyback transformer.

Here is where the manual can be downloaded and since you have a NEW LG TV you should have the manual for it. Read them both and follow the instructions contained therein. If you still have trouble. Post a new question.

Dead, led flashing red/green at first, then going to red standby
Replace C604 (1000uF, 16v) elec. cap. It is in the decoupling circuit for the 5 volt supply
Red led blinks on / off, TV does not turn via power button and/or remote but after 20 minutes or so it turns on and works fine
Replace R902, R901, R905, R903, R900A, Q902, and possibly the two (one small and one large) capacitors in the section labeled as the power supply. The board will be black under the components that are bad. Q902 is an NPN transistor and is hard to find.
