SOURCE: when you turn the tv
Do you mean the screen turns on briefly or the stand by light just keeps blinking. If the tv turns off after switching on then it probably means a protection circuit fault. Also please provide me the number of times it blinks before it pauses. Awaiting your resposnse.

By blinking 5 times I will assume that you mean the standby light blinks 5 times approximately 1 second apart, then pauses for 3 seconds and repeats. If this is true then you have a fairly complicated problem which could be anyone of three different areas. If you are not trained in electronics you will probably need a technician to solve the problem.
The problem is on the A or C board or it may need the screen drive turned up. One the C board check Q705, 732, 761 and all associated components. Look for bulging capacitors and replace as necessary. On the A board check Q218, 219, 220 and any associated components. Also look for bad electrolytic capacitors as above.
This is only a small part of what the problem could be and without actually looking at the set and doing testing it is difficult to recommend any further action.
I have a tip at http://www.fixya.com/support/r4425498-basic_standard_tv_troubleshooting which might help track the problem down.
