in dire need of service manual for apex tv GB4308

[cherrydlight]

If anyone has this please let me know! We bought this t.v. out of the paper and have had it for 3 months. It is said to have been bought around Christmas of last year. Our problem is that it won't turn on. It has worked great up till now. I turned it off to leave and when I returned 2 hours later it won't turn on! The LED light is supposed to be green when it is powered on, but it is yellow and flashes to red. HELP!!!
