The lcd tv light blinking problem.
\015\012in the lcd tv there are three main parts
\015\0121)the inverter board(pannel)
\015\0122)the main board .
\015\0123)the power supply board.
\015\012----------
\015\012if there is no power at all them main board is faulty.if no front led light is coming ON there is no power .so the main board is faulty.on the main board there is a fuse located you have to replace that and check first if still no power main board needs to be checked and replaced
\015\012---------------
\015\012if there is no sound / no picture and front led light is ON but its red then its inverter board panel problem.if this is your case replace inverter panel.its located in the lower side of the lcd in the inner area below the main board.
\015\012-----------
\015\012but if there is just front led light blinking , but no picture or sound then its power supply board problem.
\015\012------------
\015\012on power supply board there are some capacitors and ic located.if any of the component gets short or budged up then it short the power supply board.so you can check the components on power supply board with multimeter and get it replaced by using soldering iron.
\015\012----------
\015\012also you can get new replaCEment power supply board.this clears the problem completely. but as you have replaced the power supply board ignore the power supply board but check out the connections of power supply board .check the inverter board.
\015\012---------
\015\012you can get the required board and components at ----- www.partstore.com -------- or from ------ www.radioshack.com ----
\015\012---------
\015\012if you are not familiar with doing this you can get it done by local tv repair technician familiar with this model tv.
\015\012This will help. Thanks please keep updated.please do rate the solution positively .thank you for using fixya
