Question about LG 52SX4D 52" HDTV

6 Answers

LG DLP not turning on

I have an LG DLP 5SX4D-UB...when turning it on the white light on the front panel flashes from bottom to top for several minutes. Then the top light goes to a solid red and the second light flashes red. The TV never turns on. The second light that is flashing has the picture of a light bulb on it. Does this mean that if I replace the bulb that the TV will work again. I've been reading several internet sites that have folks saying that they replaced the light and their TV still doesn't work. Any idea what the true problem would be? The TV is 3 years old.

Well i know what the problem is... if your getting the white scroll and then the red light flashes but the fans are comming on and you got a new bulb the broblem is the ballast. i know cuz i had the same problem and a good friend of mine has a tv shop and i had him look at it but the good news is that its not that hard to change. if you try to go through LG thay wont be able to sell you the ballast if your just a coust. good news is that you can fined the ballast on ebay from LG DLP not turning on - s.gifeasywaylamps its about $130.00 bucks shiped. bad news about is that thay are from china(it is where i got mine) but it works great and hasent gave me a broblem yet. if any one eles has the same problem and it was something eles.... PLEASE POST IT. i hope my info has been helpful to someone.... thanks Brad Ross of East Moline Illinois... you can email me at plopit40@yahoo.com

I have the same problem but the thing is that I take out my bulb, put it back in and the TV will work fine for the next couple of times I turn it off and on. Then it iwill stop working and I have to do it over again. LG told me it was my bulb. But the thing is my bulb works fine for hours at a time until I turn off the TV.

Blinking green power light on WD65737 for a minute or so then shut down, Will also go to welcome screen and then shut down


Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.

My LG turns off in the middle of a prgram then i hear 3 clicks intervals until i turn off at power point as remote wont do it. Only started doing it this week . TV not old & never had problem before .


The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

LG LED TV has sound but no picture. Went out all of a sudden. Image shows with flashlight. Flashes for split second on power up and power down.


Your screens back light has most likely failed and or the voltage controller for the back light, both should be replaced.

I have sound but no picture on my tv


This is a popular question. Most of the time you either need to make sure all connections are not loose or just need to turn off your tv and receiver and unplug. Wait for 1 minute then reboot.
I recommend this short video as it walks you through some diagnostics for other possible problems.
