Hi, i have a samsung 42" flat screen thats just over 3 years old. Last night we had a power cut and when power came back on the tv didnt. It has power going to it as light is on but all it does it click every 5 seconds as though its tryin to turn on. I left it unplugged all night but just tried it agin now but its still the same. Any ideas?

Capacitor(s) could have been the root cause of the problem but unfortunately modern electronic circuits tend to be like a line of dominoes so when one component fails, it rarely fails alone...

You have my sympathy. I enquired at a large local electrical retailer while I was looking around for a new fridge and the lastest huge and hugely expensive plasma screen tv caught my eye. I asked the sales chappie about how long they lasted, about repairs and suchlike. He told me they last about 3 years and no one ever has them repaired - as if I believed that.
Looking around though, few electronic or electrical items have a warranty that exceeds 3 years and many that have more than a one year warranty carry a price premium, though that same retailer would extend the warranty indefinitely for an annual charge. It is in fact nothing to do with the manufacturer or retailer standing behind the quality of their equipment but in reality it is similar to calculating odds and making a wager and in the matter of wagers there are winners and losers, though the casino never loses...

As Samsung have paid for their mistake and seem determined to pay no more, to make any exceptions would be like admitting liability all over again and reopening the floodgates. The only possible way forward would be to obtain an engineer's report and the serial numbers of the affected tv sets.

A modern tv is in fact more computer than tv and contains the same ultra-sensitive Cmos circuit chips as a computer which could have been damaged by a voltage surge a year ago and finally failed last night. Perhaps the problem isn't capacitor related...

Based on the information you described you may have a tuner
circuit problem or power intermitent faikure fron the power supply module.

Hi.
It appears that your are having a tube failure issue.

Either that, or you have a capacitor problem.

Both can act like that, but as a rule the tube acts more like that when it fails than the other parts of the tv.

The tubes are replaceable, and are available from Fry's and BestBuy.

If it winds up that it is the capacitors instead, then I would take the tv to either Fry's, BestBuy, or RadioShack.
These companies have specially trained techs for just that repair, as it takes special skills to deal with the voltage and power that capacitors can hold in them.

I hope that this helps you out some, and good luck!

IS HE SCREEN TOTALLY RED !! if yes check power supply all voltages if normal replace x board

It depands if you watch say 5 hours a night times 7 nights 35 hours a week times 52 weeks a year. you be suprise.

The x-sus or y-sus panel wil be the fault.Check the fuses on these panels ,if one of the fuses is open then that panel must be replaced.Not verry cheap to replace.

swollen capasitors, replaceing will cost $500, so best to get another one, 42'' samsung will sell for about $800. the pn42a450

once a plasma has a problem, fixing it or not, more problems will occure, trust me, i am the flat pannel guru.

you ip board is bad go t0 this site partstore.com typ in the modle of tv and buy it . works like brand new .trust mr it did and saved a lot

DLP --- need to exchange the thermostat.
LCD --- replace the Main Board.
PDP --- need to check Power Board or Y-Main
