Our bedroom TV is a NS-LCD26A Insignia LCD TV. I've read all the posts and solutions on everything I could find for this TV and nothing has worked (Sounds like these are one of the junkiest TV's around from all of the unit failures). I currently have the back off of the TV so I can see all the parts (diodes, capacitors, etc.).
The TV worked fine for 14 months then when powering up it would not show the "Please Wait" message what was typical of the power up sequence and then nothing but a grey screen with colored streaks slowly morphing around the screen came on. Currently still does the same thing every time. I'm sure it's something that has gone wrong with one of the circuit boards but I'm no TV expert.
Thank you for your time.

Hi,I fixed my here's issues i had and the fix i did..
Every now and then i would get snow and a pink picture.
Then tv stop turning on .
To fix i seen on main board capacitor cp25 and cp28 near the heat sink was bad
They were both 470uf 35v...
on the power board i seen c531 47uf 50v was bad.
i also heated up the heat sink on the main board to resit the chip ,,
and tv now works
I didnt bother putting the huge shield back on main board i figure it was a issue to over heating the cpu instead take the hit to the brain from the fcc radio wave lol
First do the 3 caps and see if it works if not then do the blow dryer to the heat sink on main board
I would suggest trying to repair the board first before buying a new one (unless you get a great deal on a replacement one). Its possible it was something simple like a fuse or busted capacitors.
Open up the TV and take out the power board and check it for any busted capacitors. Also check the fuse(s) with a multimeter. Try replacing everything with a soldering iron (shouldn't cost more than $10 for a fuse and capacitors). Try and see if it makes a difference. ONLY DO THIS IF YOU ARE CONFIDENT and SAFE with that type of work.
