Hi I have a 2003 zenith projection tv model no. R49W36 and just recently the tv started acting up. When it first started the pictured showed up completely red. Then it began to fade and power off by it self. Eventually the picture completely went out an there is only sound. I was told to take the back off and check the boards to see if any of them were burnt out. From what I could see none of the boards were burnt. I really need help figuring this out and if anyone could be of assistance it would be greatly appreciated. THANK YOU !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
