Hi All,
Today my mother's 2.5 year old Samsung P2270HD has developed a screen issue. As there is little to lose, I thought I would have a go at fixing it (despite having no experience in TV repair ... although I do repair PCs, Laptops and Phones on a regular basis!)
When turned on the screen is a very light grey colour, with a brighter area on the top few lines of the screen. Pressing the Menu button causes these top lines to change colour/brightness. When plugged into a source, after the set has warmed up it shows a very dim and slightly corrupt image.
From my initial research it sounds like a t-con issue, although I am an absolute beginner at TV diagnostics (having just spent an hour doing some research, and that is it!). I have done a short check of the boards, and the capacitors all look ok & nothing is obviously fried.
Inside the unit are two boards:
BN-41-01245C - This is the main logic board, which has all the inputs and an output to the panel.
IP-54135B - This is a combined Power and Inverter board.
My questions are:
1. Do you think my thought that it is a t-con issue are correct & what other possibilities are there?
2. Is the t-con on the Logic board or the Power board?
3. Could you make suggestions on where I could purchase a replacement from in the UK?
Thanks very much in advance for any help given on this issue!
Mike
