My Coby TF-TV1500 15" flat screen panel tv suddely started having problems. My daughter watches this in her room. The picture & sound will shut off and come back on while your watching anything. It just blanks out and comes back on every so often. The picture color is also off now since this all started and sometimes the picture looks wavy. Sometimes the picture will go dark. Don't know if its worth fixing. Any help would be appreciated.
