5 blinks is error code for short on 140 volt line inside the set; it usually means the Horz output transistor is shorted. If you have a ohm meter (used for checking fuses etc) there is a simple test to see if this is the problem. Also associated with this is a bad capacitor near it (Location for the Transistor is C509 and the transistor should be location Q551 How do i test them?What should the readings be?

Resistors are usually cylindrical, depressed in the middle and have three coloured rings (sometimes 4) around it to show the resistance value (but they do come in other shapes as well). The leads are generally on the base, one on each end. They are usually placed length-wise on the board. Here is a sample pic:

Capacitors, on the other had, are usually cylindrical all the way through and are encircled by a plastic sheath. Sometimes they look like small rectangualr compressed boxes.The leads are usually both at the base end on one end only. The top or cap is usually visible and point upwards from the board. They have their values usually printed on the plastic sheathing.
Here's a sample pic or two:

Hope that helps, and dont forget a Fixya rating!

As you look from the back of the set (with the cover off) it is on the far right large board, C509 is the location number--it will be printed on top of the board under the cap.

It is about 2 o'clock near a large plug--on right side of right board--the one with the large gray transformer with a large red wire--part is forward of that transformer and red looking in color--two leads---it will have the C509 printed on top of the board under it.


This is a common failure part is this set--some will have a physical crack in the red part and others will look perfect-----value with a cap checker is .47 UF----200v is the working voltage --as long as you replace it with a cap of at least 200 volts of the same value--it will be fine--

There are two ways to get at it--pull the large board it is on OUT--I do not recommend this----or pull the whole light box out---very easy and safe---if you locate the cap and want to know how to pull the light box out let me know--

If this has helped you rate this solution as I do this here for free.
