Sansui HDLCD4050C 40" TV -Horizontal Lines bottom half issues. What is wrong?

I bought my Sansui HDLCD4050C 40" tv last Feb 2012 at BJs Warehouse. It is in perfect condition and has had regular daily use. never bumped or dropped and regularly dusted. Today suddenly I have a horizontal line thru the middle and the bottom half is either a different color, flickering, or a lighter contrast depending on what is showing on the tv. What is wrong?

It sounds that the vertical output section has the fault. Contact any service technician. Products powered by electricity should be serviced or repaired only by experienced professional technicians. Any attempt to service or repair the product by anyone else could result in serious injury or death. If you are not familiar with electronics, do not attempt to repair. Whether you suffer fatal electrical shock. Instead, contact the nearest service centre.

That model of tv has problems with the bulb overheating. Just try to keep it from getting to hot, and let it cool down if it happens.

SOURCE: Sir, My Sansui TV has switch

I suspect a power supply fault. Check for dry joints around any heavy component, transformers, heatsinks with transistors on etc, as they are most likely to suffer from dry joints.
Hope this helps.

Firstly, the extended warranty is a very cheap insurance, because the labor could be as high as $168/hr. Instead of putting $200+ in this unit, I would purchase another with 3-5 yr warranty.

Ten years is two lifetimes for a Plasma, it most likely is either the display panel itself or a main board, in either case not cost effective to repair or smart but the real problem would be parts, I bet almost zero is available for this.

Take it back to the place you bought it from they will most likely fix it if you have a warranty. Thats your only choice if you want it fixed unless if you wanna pay a hundred bucks to get a 3rd party lcd put in it haha.

This is a sign of your LCD panel beginning to die. Sometime soon those lines won't fade away and will become permanent parts of your TV screen.

Considering the fact that your TV is approx 3-4 years old, this is normally the expected lifespan of a TV. Once the TV becomes unwatchable, your best bet would be to begin shopping for a new one.
