The antenna port is broke off on my lg flat screen tv how do i fix it


It's possible to resolder the port back on but the tv will have to be pulled down to gain access to the tuner and tuner cover will need to be removed to resolder the signal wire where it's broken off the tuner board. In some cases the tuner needs to be desoldered and removed to get access to the tuner board. If your soldering skills are not great an alternative solution would be to use an external set top box. This can be a pest because you then need a second remote to change channels.

24inch Bush smart TV/DVD not working.


The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Sony Bravia flat screen TV when turned on has black screen. Green light on the bottom is lite up, electric plug is plugged into house socket, no picture only black screen.


If audio is OK, the fault is with its backlight section. If audio too is absent, the fault is with its digital main board. If you wish to get more details visit the site linked here. Pull up older posts.
