Question about Televison & Video

1 Answer

I have a LG RU60SZ30. I had a technician come out a couple years ago but can't remember what diagnostics were. Want to try to fix it now. The problem is that the operating light (left light) is red then I turn the tv on and the same light flashes for a while an amber light then clicks back off to red. All on the left light. Just purchased a new bulb and hoped it would fix it but still same result. Any ideas ? Help me please.

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.
Search the site by type in the "brand name" to your device, [Exclude the model number] in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

SOURCE: TV doesn't turn on

You really should give make & model number when posting, it helps us immensely, your lamp and possibly the ballast is bad, start with a new lamp first, odds are very good that it will fix your problem, can`t help more without manufacturer and model number, good luck, ps, order the original lamp, generics are junk and a waste of your money.

Please put back lamp (bulb) cover properly and check as lamp cover is open/ not fixed or improper fix is also cause of LED flashing.

SOURCE: power light flashed red 4 times then repeats no pic,new bulb/fan!

Check the fan that cools the bulb. It is directly behing the bulb. It should turn on when the power comes on. It apparently has a safety to protect your tv(and home). mine is in the process of going out. looking for online solutions as we speak.

You may have to have a tech look at these voltages and get the correct Main PCB or Freezer Fan Motor for this unit. Awhile back, LG had a problem with "icing-up" in the freezer around the fan blade. They came up with a different Main PCB which lengthened the defrost cycle and adjusted the freezer fan cycling times.
