Two LCD issues

BohsCeltic

First one is a 42 inch philips and the power capacitor has blown, would this be worthwhile getting fixed ? TV IS 4 years old

Second is a 32 inch walker(opened it up and its samsung components) and the screen has gone funny. I've tried both HDMI and scart but still the same. Any suggestions ?

This is what it looks like

What do you mean by "Power Capacitor" ? Have you seen the faulty component or is it pub theory ?

There will be several electrolytic capacitors in the PSU that can swell and cause intermittent issues at power on - may decide not to power on or come out of standby are common ones. Recently replaced 2 x 4,700uF 10V caps that were visibly swollen in a Hanspree LCD that had these symptoms. 3 euro for the components in Maplin and about 1 hour labour.

The components themselves are cheap, less than a few euro, though using higher temperature rated caps is to be recommended (105C rather than the common 85C components). If you're any way handy with a soldering iron you could do this yourself. Have a look here to see what a swollen cap might look like. They are usually higher capacitance ones that swell but not always.

As for the Walker TV, could be a faulty LCD panel but worth checking for bad caps in the PSU also.

Two repair shops told me this but were looking for just under €200 to repair. It seems a bit on the expensive side seeing as tv's are much cheaper now.

Just before the tv went it actually heated up the living room it was that hot.

I'll have a look at what you suggested, thanks for the reply
