It ended up being a combo of 3 boards that needed replacing. No one knows why and I have a $200 monster surge bar but it seems as though the tv just had failures all over the place.

WARNING...The ballast can output 3000volts when it initially fires the lamp. Without the proper test equipment you could injure or even kill yourself. You've verified that the lamp is good and now suspect the ballast?

Orange blinking light under a small picture of a light bulb? Then turns to a red light?
Sounds like the same problem I had when I picked up my LG 52SZ8R. After replacing the lamp the TV ran fine.

Easiest way to see if the lamp is the problem is to take it out, and look at the peice of wire in the globe as you would an old light globe.

If you need help, download the following manual, and look at page 9.

If it does come down to you needing to replace the ballast contact: http://www.statewideapp.com.au/index.php?selectedContent=1188381775
They should be able to give you a quote and part number, if you don't like their quote you can always use the part number to search for one thats cheaper.

Lg 52sx4d problem


If the red light scrolls through, you need to replace the bulb. I replaced the my own bulb, and when I tried to turn on the tv the light kept scrolling. What was wrong? I DIDNT FULLY REASSEMBLE THE TV AFTER REPLACING THE BULB.

Make sure that all the screws are put back in and it will probably work if you have replaced the bulb.

The lamp is fine but....


The Lamp Ballast p/n 6316000009B could be bad if you already swapped out the lamp with a known good one as you can't tell by looking at them if they're bad. It may be worthwhile to have a technican look at this set as it would be an expensive mistake if the ballast is not bad.
