First , i would doubt very much that the remote is sending power on signals to the tv evven if it was left pointed towards the tv but you could still try to take it out of the room for a test.At this time only the main board can turn the tv on by itself but i also doubt it is the culprit .What i can see as the first suspect would be a poor filtering of the supply voltage that causes false triggers at the main board .This poor filtering would be caused by weak / vented 8 years old capacitors on the power board .Of course without being there with tools and meters i cannot be 100% sure but i give this a 90% chance on the power board and the other 10% for the main board .This means that you either would have to refurbish the power board or replace it .This power board part # ***** cost around $60 and by the look of it so far may be difficult to findThe main board itself cost around $80 , the parts are surprisingly expensive for this 8 years old 19 " tv .

I probably can find that power board but again if i may be frank , considering the age of the tv at 8 years old and the fact that you can get a new 32" tv with all the bells and whistles for around or less than $200 ,I would think twice before investing that kind of money into this one.

Repair shop would be out of the question as you could be looking at $150 .If you need to find repair shops near you then look at the link below and enter your zip code ;www.tvrepairpros.comThis will give you a list of NESDA member repair shops in your area.This list may be limited though and you may find more by simply using the yellow pages or simply google "tv repairs" and the name of your town .You could give a call to different shops in your area to get an idea of their rates , it pays to shop around.

To get back to your tv , let me take a look and see if I can find that board
Ask Your Own TV Question
TV Technician: Jack, Technician replied 1 year ago
As I thought this board is nowhere to be found and the only link that has some potential would be this one but you need to contact them for a quote , that is direct from china ;http://www.buyqual.com/715t2906-2-8942apr1-philips-996510011600-power-supply.html

The thing is that this tv is still working but it has a serious glitch and the easy solution is that switch indeed .After 8 years it may be on its last leg and again I would not recommend investing money into it , the new TV's of that size and larger are cheap and any money would be better invested in a new tv
