Question about Televison & Video

3 Answers

My Westinghouse SK-19H210S LCD TV will not power up. I have checked the initial power and it is providing 80 VDC. The standby LED is not lit. The power switch has ~2.7 V on it that goes to 0V when depressed. I need information on how the power supply switched on.

RE: Westinghouse SK-19H210S LCD TV Power Problem

I know another who had a similar power problem and when they looked at the capacitors on the power supply board they found one of the capacitor cans had a bulged top indicating damage! It turned out the 2200uf capacitor was indeed bad and so they had it replaced and the TV was fixed!

The high voltage power supply has failed, this is around $600 to repair, I recommend you buy a new LCD, they are very cheap now and have vastly superior pictre quality to your projection system.

Hi!
Please check for the connections near the transformer, also check the filter circuits and diodes on the power board.

    Also, check for the blown fuse

    And, if you find components other diodes/filter circuit faulty then its probably the issue with SMPS Regulator/Controller and these parts are not available easily.


    And, if you want to buy a replacement power supply board for your westinghouse you can buy it from---

    Please ask for further clarifications


    Thanks

HAVE AN BLINKING CODE OF 2 SHORT 3 LONG UNIT ITSELF MAKES A (POWER) CLICKING NOISE WHEN I TURN ON IS THIS SYMPTOMS OF A T-CON BOARD REPLACEMENT OR PERHAPS A POWER DIST. PROBLEM


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.
http://electro-medical.blogspot.com/
If blinks continue without any pause, the main board is faulty.

TV comes on to standby, but with record led flashing. pressing power on , power light turns green for 1 second, click from within unit, back to standby with record led flashing


Hi,

Initially, have you tried a full hard reset? If not, pls unplug from the mains. Most current devices would reset and revert back to factory default settings (assuming no internal hardware fault) when unplugged for a considerable period of time (a couple of hours).

Pls post back for any development(s) or even the lack of it.

Hope this be of initial help/idea. Good luck and kind regards.

Thank you for using FixYa.
