Have TV Questions? Ask a TV Technician
Hi , I`m Jack Perhaps I can help you with this problem but first could you please send me a reply when you see this ?
From your description this is typical of weak/vented capacitors and i will guess that this tv is 5 years + old ?
could you please give me its model number ?
Sorry but that is not the TV's model number , that is a part number on the tv , Samsung puts those BN64 , BN44 on just about everything
Your TV's model may start with the letters PN50 for 50" model PN42 for a 42" model etc.
Let me see if I can find to which model this part number may belong to ?
Yes , that's more like it thank you
Fair bit younger than I first figured too !
You said that this problem gradually got worse over the last few days/weeks ?Once it is warmed up (1 hour or so) , can you turn it off and on right away normally ?
You mean that even after the tv has warmed up you have difficulty turning it back on ?
Even if it is off and right back on ?
O.k then and about the remotes that stopped operating it , not sure if this is related but once the tv has warmed up do the cable remote works the tv again ?
O.k then I`m a bit confused here , you said above it would turn it on ,and then what ?
It stopped turning it on but still turns it off ???
Never mind that last reply
What you have then is a defective main board part # ***** first and a distant second possibility would be the power board but again that's a long shot.
How do you want to proceed from here ?Look into this yourself or the repair shop ?
Let me know and i will help you along if you wish to look into repairing this yourself ,otherwise i will give you the details and costs you could expect.
O.k then I can tell you that this board if bought brand new from Samsung will cost $255 at the link below ;
Or it can be bought used from independent resellers for around $100 to $150
If repairing this yourself is not your cup of tea so to speak then to have this repaired at home could cost you around $175 +parts and perhaps $50 less if you take it to the shop yourself .
If you need to find repair shops near you then look at the links below and enter your zip code ;www.tvrepairpros.comOr this one;http://www.tvrepairman.com
This will give you a list of repair shops in your area.You could give a call to different shops in your area to get an idea of their rates , it pays to shop around.
