Tv wont come on
Most times when you hear this kind of sound on a TV it is because the flyback transformer is bad (from what I can remember anyway!). Its been a while since I repaired TV's, so hopefully someone can verify my info. The flyback transformer steps up the voltage very high which powers the color tubes. If that is bad, you will get the thunk sound. Also, if memory serves me well, there is a high power output chip that could be bad as well. Please, anyone who knows TV's, please verify for me. It has been years for me!
Why all my cables channels not working
if you are using coax cable to conn cable box to tv, be sure to use the analog ant conn on back of tv, and there is a switch on the back of the tv for selecting channel 3 or 4, for cable box use. be sure to turn tv to the same channel the switch is selected to, and always use the cable box to change channels/ programs, not the tv channel selector.
I replaced the screen on my 62 inch projection TV for about $50 and the the picture quality is good! Have a sheet of plexiglass cut to the EXACT size needed. BEFORE installation it MUST be frosted on both sides by either a fine particle sandblaster or by sanding it VERTICALLY on BOTH sides with a power sander and a fine grade paper.
If this is only an OUTER protective screen and the image is projected on the inner screen then DO NOT frost the replacement screen, just install it.
I have a 52" RCA
Check your DMD board fan. Make sure it is spinning. This fan is the #1 problem for this model not turning on. This fan keeps the DMD board cool while working and if the fan does not spin your TV will not turn on. You might need to replace it if it is not spinning. If the fan is spinning, then check the color wheel. If it is not spinning your DMD board is not working and should be replaced.
