Vizio 55 inch TV "Vizio E550I-B2" is Darker on the left viewing side, replaced the Power Supply board. And the Screen is still dark on the left side. Any suggestions?


It is a common problem for this TV, it uses a Sharp LED display panel. The problem is the data buffer IC inside the panel ether shorted, or burned open.
Vizio offers a extended exchange warranty if you have the original sale slip.

For more information, you may contact Vizio directly.

LG 42' plasma tv


Hi,
Based on the symptom it seems like you have a problem either with capacitors or mosfet ic's burned on power supply. I will open up the tv and closely inspect for any burned/damaged component. (google burned capacitors for you to have an idea on how they might look like). If you find any you can either replace the component or you could also replace the whole circuit board. The specific part number must be print out on the board itself. You need this number to order it from any part distributor.
Good Luck!

Lg tv


How many times this standby/power light blinks at one time switch ON? Count it carefully. These blinks are fault indication, and known as blinking codes. From the number of blinks occur at one time switch ON; you can get an idea about the faulty circuit stage inside the TV. This will make repair easy. For more information, check the link http://electronicshelponline.blogspot.com/. If the blinks continues, and non-stop, the fault should be with its main system control IC, and with the memory IC.

The 37 " lg tv


Hello,

It's the problem of overheating in the power supply board of the TV.on the power supply board of the TV there are few capacitors and IC.any of this IC is got short or may be weak.so due to this when you start the TV the current passes from electric outlet to the power supply board of TV.but when the current passes from that weak/faulty part at that time current gets stopped or slow and the board overheats and TV shuts off. this is a common problem faced by many other users too.the possible option to solve this issue is to check the power supply board by a meter and continuity tester and replace the faulty component on the board which is short due to which power supply board is getting overheated.its bit technical job but yes its not at all a costly repair to do or get it done by the technician. for required parts it can be easily available from local electronic hardware shop.

Hope this will helpout....

LG TV RT29FC85VW 29" woofer not working


Check the Woofer for continuity and also with an external amplifier.
if there is no issues then the sub-woofer power amp IC can be faulty.
Check the main voltage to the IC, if not present the power section must be traced for a line break, fusible link.
If there is power , then test for input signal to the IC. If so the IC can be the supect.
