LNT4069F takes 30min to startup HELP!

post #1 of 12
Thread Starter 
Hi All,

Just received a call from my parents indicating that their Samsung LN-T4069F takes about 30 minutes before it will startup and play. During this 30min outage they hear a clicking sound, and noticed the blue light comes on and off, but the color isn't as strong or bright as normal.

They also noticed that it will take longer for the TV to startup, if they leave it off over night. During the day, after the TV has warmed up, they can cut it off, and back on with out an issue.

Any ideas what maybe causing this problem? They had this TV for about 2years now without any issues.

Thanks.

The power supply module in the TV is going bad, pretty soon the tv will no longer power up, happened to me on my 4671. Apparently a service tech posted an article stating this is a wide spread problem because Samsung is using crappy components.

Is this covered by warranty, or is it possible if I can order the part, and do the repair myself?

Thanks!

It is under warranty if the Tv was purchased within one year, and if you register online you can get another three months. If not you can certainly diy. You can either solder a few new capacitors onto the board for less than $10, or you just replace the whole board for $75.

Where can I get the part, and instruction on how to install?

$75
If you can put a video card into a PC, you can change the power supply board. Just handle the board by the edges so you don't get electric shocked from stored voltages (especially transformers and large capacitors).

Again, where can I purchase the board? The cheapest I find is for $179.00


Thanks.

Definitely power supply. Should be pretty easy fix.

Thanks all,

Having double images with this set now. Can anyone confirm if this is a blown capacitor?

Call Samsung. Here is a link to their program to fix long startup times and related problems:

edit: Oops, didn't see the original date. Well, maybe others seeing this thread can benefit from the Settlement notice.
