Question about RCA F36665 36" TV
TV will turn on fine, works through all menus fine, sound works fine, problem is that on any station you have no picture. You can hear the channel that you are on but no picture. I have removed rear cover and blew the dust off (not very dusty), checked all connections for tightness ect, TV was working fine and then just quit showing picture. I am not very familiar with TV problems and my experience level with them ends with with watching one. I however am capable of fixing a PC including basic electrical trouble shooting so fixing it including changing out components isn't beyond my knowledge. Any Suggestions on where I should start??
This might be a simple problem or a more involved one and for that you will need the service manual to check different voltages,is good you are somehow familiar with electronic servicing,first you need to remove the back cover and reconect just the cable signal and the power cord,make sure the chassis is seated properly in whats left of the front cabinet then turn the set on and scan for channels if you still see no picture tap lightly with handle (not Metal)of a screwdriver in the chassis to see if the set reacts to your tapping if it does you will be looking for a loose conection and should be easier but if the set does not react you will need to order the service manual from http://www.servicemanuals.net/ ,in there you go to service manuals and put the model number,they will give you a price. Once you get the service manual you need to check the voltages to the signal processor IC to see if they are there specially the B+ supply to this IC.Let Us know if you have any more questions.
