Older Sharp LC-37DB5U. Power and OPC lights blink 3x and then repeat, over and over. Is this worth repairing?

    The problem is that the set will not turn on at all, not from the set's power button and not from the remote. I tried unplugging the set and plugging it in again and nothing. The set is probably 20 yrs old so I was just questioning whether it was even worthwhile to fix it. The last time it was used, maybe a couple of weeks ago, it worked fine.

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

How many times per second does the POWER led blink? (dont worry about the OPC).

1x per second (constant, steady blink) = bad inverter/lamps
2x per second = bad power supply
3x per second = bad main board

There isnt really anything you can do to fix it yourself, youd have to call Sharp to locate a local service center.

No POWER


How many times does the POWER led flash per second? (Dont worry about the OPC).

1x (steady constant blink) = Lamps or inverters
2x = Power Supply
3x = Main Unit

If i am reading it correctly, looks like the POWER led is flashing 2x, which means it is a power supply failure. Either way, your TV needs to have a board replaced, there isn't anything you can do to fix it yourself. Try locating your local sharp authorized service center to repair your TV (1-800-237-4277)

How many times does the POWER led blink per sec? (dont worry about the OPC)
