Ok
I had brought a faulty TV for very cheap , knowing it was faulty , in hope that I could repair it .
Symptoms:
Upon initial inspection , I noticed there is impact damage to the top corner casing , though the screen seems intact and clean. The TV once plugged in shows a standby red light , I can press the power button and the TV then makes a short humming along with a short buzz which lasts for 5-7 seconds . The TV LCD backlight appears to then come on , though the screeen remains plain black for approximately 1 minuite .
after a minute or so various thin cloured lines start slowly appearing , until It finally settles like this :http://img268.*************/img268/9902/dsc1042zm.jpg
I then dismantled everything , and Visually checked all the Caps , connectors and soldering Everything looked fine . I double checked and re-plugged the ribbon connectors on the T-Con board . I tried to turn on TV after checking over , though it is still the same
On a plus note , apart from the LCD panel and housing all replacement parts are available on Ebay . I am currently watching a replacement inverter board and T-con board on Ebay . Seems like this TV uses a TCON board that is also used in Sony models
Judging by the damage on the TV housing , I have a slight hunch it may be a faulty panel , though I hope not
I have searched the internet and people with simmilar problems have mentioned the T-COn board and Cap replacements as possible solutions . What do you thing could be the fault with this TV, how shall I rectify it? I would like to be certain
Look foreward to hear from you all
Peace
