Have a Sylvania 42" circa 2006. When I power it up, green ON light blinks and the screen displays "Digital television" and nothing more. The green light blinks a bit more and then shuts down to red light - stand by.
A Google search points to a bad power supply or capacitor. Any suggestions before I make the trip to Best Buy for a new unit?
Thanks :cry

Given the costs of a new tv now a days and the lack of tv repair guys may be less headaches to get a new one. That said if you have a repair shop nearby a phone call wouldn't hurt.
Good luck :aok

The capacitors of the power supply are often the culprit in such cases. Changing them is not rocket science, but there's a reason why opening the case is only allowed for qualified personnel. If you aren't one and you open it and either kill yourself or burn your house because of the lack of said expertise, you can only blame yourself. Our local repair shops change the caps for some €70 including VAT, don't know the pricing at your location. The caps cost about €20 bought one of each type needed. I guess very few repair shops have them in stock in such large quantities that the prices would be lower.

Max, as Bizman posted, most times it is a capacitor being popped or such..
I replaced 2 of them in my sister's Sony LCD 55 incher... It only cost me roughly $18.00 and about an hour or so from taking the back of and using my uei meter that has a capacitance checker on it...
Finding the bad components, reading the type/model # and ohms etc... So you can either go to radioshack or local electronics/electrical supply house or if needed, I've used Amazon before to get parts... You need to be very proficient in ability to solder in small confined areas...
As for possibly getting a new LCD tv... A new 2013 or 2014 model will most likely be leaps and bounds beyond that 2006 model... My Samsung smart tv and 3D BluRay system is 2 yrs old and makes my parents '05 LG LCD tv seem ancient.... Just saying...
Best of luck, which ever way you decide to go.... Also, don't junk or get rid of your old one if you decide to buy a new one... Try to fix it and keep it or sell it to recoup some of your money..

Also you can now find some very thorough YouTube tutorial/diy fix it videos on how to repair TVs, LCD monitors, etc...

With a TV that dates from circa 2006, could this be due to the dreaded Capacitor Plague?

I had an LCD monitor i replaced the capacitors on it and it worked just fine. I think there was four or five. Bought mine at Radio Shack. I have soldering skills so I knew what I was doing. Several videos on the capacitor problem with LCDs.

We've been referring to that from the very start but anyway, the picture shows what to look for. Good reference. :salute

Every monitor in my house has been through this. It's not hard to fix, but it does help to have a good solder iron. There are several electronic houses on the Internet you can order capacitors from. You can probably find the schematic online for your particular set. Probably you can even find videos on youtube by now.

There's not much inside one of these units,a power supply and a circuit board,either could be causing the issue.
I resently had the power supply replaced in a TV I own,under warranty,and it was service in my house so I got to see and ask a couple questions.
Seems either board is worth about 200 bucks so you could either replace some caps or you can replace the whole board for not alot more,your choice. That said a TV from 06 should be religated to the bedroom,the new tv's are cheap and much better!

In some countries advising a non authorized electrician to do repair work can be illegal, just as a note.
Everyones free to risk what they want but one should keep in mind that they're liable for anything that may result from a bothed up repair. Electric shock, fire etc. The insurance company will have a field day if they discover you've been DIY fixing electronics and something happens ;)

Given the age of the Sylvania, lack of tools, parts, know-how, etc., I did some shopping around yesterday and found a Samsung 46" 6350 at BJ's Wholesale... on sale for $799 ($1,099 originally) Compared to the other options, the Samsung picture was a hands down winner. It has many built in smart apps/features. I'm kinda glad the old Sylvania finally fizzled out :lol
Thanks for the replies :aok

Max, If it's a socalled smart TV do yourself a favour if you plan to use the net on it and get an airmouse type device! Oh and dont forget to plug in the wifi dongle,I did and was :headscratch: trying to figure out why I couldnt connect.... :o

I've got the tv wired to my cable modem via LAN. The only app I plan to use is Pandora. And yeah, using the tv keyboard is a major PITA :mad:
