Question about Televison & Video

1 Answer

I have a Sharp LC-30 HV2U. When power is turned on, the R-1 relay clicks on and the power light momentarily goes green, then relay immediately cycles off and power light goes red and blinks 3 times repeatedly. Acts the same whether the AVC is connected or not. Got this used and the owner had the power board replaced, but same trouble persists.

These 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, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

Sharp model lc-20sh1u won't turn on, just makes a clicking sound and indicator light flashes red.


The clicking sound may be a power relay coming on and then off--problem indicates a trouble in the main power supply.

6 yr old 30 sharp equos. When I turn on red light flashs green and turns back to red immediately and no picture.


I have the exact same problem. Check to make sure the AC power box isn't making a ticking noise. It could indicate a faulty box. I'm getting mine checked out asap. I'll let you know how it goes!

Sharp lc-22sv6u won,t power on. no green light.


Sound like the TV is in protection mode. This happens when a part goes bad inside. the TV turns OFF to protect the other parts from being damaged.
Most commonly it's a power supply related issue. A bad capacitor or transformer on the power supply board is to blame.
For a do-it-yourself fixer with electronic experience, a Service Manual is the best for trouble shooting the problem down to the bad part. Normally, you can find it over the internet for less than $20.
