WE WERE WATCHING A SHOW AND THE PICTURE GOT SHAKY AND SMALLER AND SMALLER, THEN WENT COMPLETELY OUT. NO ELECTRICITY. WE SMELL SMOKE. IT IS A 27 INCH RCA, 15 YEARS OLD. I THINK THE PICTURE TUBE WENT OUT, WHAT DO YOU THINK. SHOULD WE REPAIR OR REPLACE. THANK YOU
Picture tube failure is rare problem. Your problem is powersupply failure and short circuit in deflection area. This is quite common problem. My sugestion is before you got this problem picture clarity and color clarity is better perfomance in your satisfaction means repair is better. Otherwise replace it.

If you have cable then put the cable wire directly in the TV, bypassing the cable box. If the pix is Ok it proves that the problem is the cable box. If the problem is still there then it proves the the TV needs parts inside.
Hey Jim, The high voltage protection circuit has gone out on the D-board and will need to be replaced. The fuse to the power supply is probably fine. A good repair tech shouldn't charge over $125 for this and it only takes a couple of hours. Let me know if I can be of further assistance.
video card went out in the tv. You are saying you need a schematic. Be real careful getting into tvs. They have very large capacitating capacitators in them that can electrocute you. You need to take it to a repair specialist and have them run a check on it. Sounds like the video card to me though.
