Need instruction manual for hyundai hpt 4240 42inch plasma screen- not the users manual as it is too basic

Check the speaker/s first. If found OK; check and replace the damaged component/s at its audio output section circuit board. If needy, replace this board as card basis. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" will make surf easy. Surf the site with patience. Pull up older posts.

Try a computer/electronics store. Ask for a power cable for an lcd monitor. It should be the cable you need.

went on to currys web site www.thetechguys.com were my mate bought tv from and down load manual from there very good site if any ones lost manuals

probably the x-main or y-main boards

x37sv-naga.lcd remote control

Try www.hyundai-world.com That is the manufacturers website. Good luck. Ask them if that set can played in the USA without a special power supply.

Try the Hyundai web site, or call their service rep.
