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.

I can hear the sound but i can only see the picture in Video mode and PIP mode..... LG model # 52sx4d-ub


dcooper1288,

You have a bad mainboard.

They are available at http://www.encompass.com and are not that difficult to replace. This is a common problem with the LG units and don't be surprised if it takes a while to get a board.

Thanks for using FixYa and for the generous rating.

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.

LG DLP 52SX4D/Will not power up


Ours did the same, it was the colour wheel in the tv, it was stuck [from dust and smoke] and the tv wouldn't go past that problem.
