Have TV Questions? Ask a TV Technician
Hi, I'm Pete. Welcome to JustAnswer! I'm reviewing your question now, and will post back with your reply ASAP.
Jairo, approximately how old is the TV?
How many times does the LED light blink? Is it a steady blink, or is there a pattern of blinks?
Do you have any test equipment available to carry out some checks?
Can you test the voltage outputs from the power supply board and let me know what they are reading?
My name is***** am a different expert clearly you need to replace the main-board thos is a data board and is not checkable however those voltages indicate the power-board is working so replace the mainboard, you will need to retrieve the part-number from taht board and initially try www.shopjimmy.com or google the part-number for suppliers
If you need more help let me know.
A positive rating is appreciated thank you 3 to 5 stars with the rating bar of stars at the top of the page thanks again.
I understand make sure you order by part-number only for the main-board (one with all AV connectors on)
I can't answer that because I do not know your skill level practically?some people get frightened looking at a screwdriver so I just can't answer that question, what you will need to be able to do is get the board out and solder the devices onto the board, if you do not know how to solder you may need to get someone who can OR follow any youtube videos on soldering....
I don't understand why you want to know that you need to understand how a bridge rectifier works before wanting to know that but there should be in excess of 200vdc then this voltage is upped again by a reservoir capacitor and then smoothed by smoothing capacitors, it is strange how a bridge rectifier is still used today but there really is no other way fro the hard ac input
Let me know if you need more help
No please I do not use the phone facility myself and yes it will cost more
