Samsung LCD TV 32" fullHD won't turn on

[jagabo]

Jagabo... I have a Samsung 32" LN32B360C5D... everything works but the video. When turning on the TV it flashes a picture about 4 times then goes black but the sound works. The power supply is working.. I know this because I already bought a power supply board that just came in today and its doing the same thing. I was thinking of replacing the main board which runs about $70.

My question is.. did your TV behave the same way with the sound working and picture goes black after turning on?

No, mine wouldn't turn on at all. When power was plugged in it would click once. When the power button was pushed (on the TV or on the remote control) the red front panel LED would blink a few times (four times, I think it was, probably a diagnostic indicator but I couldn't find any reference regarding it). No sound, no picture. But the board I replaced was the CPU board. But failure there could cause just about any symptom. Good luck...

Well I just bought me a main board for the TV which I really believe is the issue. Another forum with a tech answering customers problems has said it was the main board cuz the customer said that when he used the blow dryer on the main board video comes up and also if he turned it off it wouldn't come back on again til it warmed up and now nothing.

So I am getting mine from eBay that was listed for $75 free shipping but could put in BEST OFFER and was accepted for $60. Will keep yal posted if this resolved the problem.

Cheers

Well.. the main board came in today and replacing it was very easy... didn't work. TV still comes on with sound and flashing pix about 5 times then goes black as before. More research! LOL!!

Of course, we are having the same problem w/our 32" Samsung LED and I see a link to find capacitators.....from one that isn't very handy in the repair area, (and I haven't diasbled the TV yet, but know this IS the problem!) what capaciator should I be ordering?

Joellyk - Please note that not all Samsung TVs have bad capacitors. There's a list of models on the internet and manufacture dates. You should consult that before you make any decisions that this for sure is your problem.

I am a bit tired of saying this, but replacing capacitors is not something just anybody can do and I find it misleading for people to consistently suggest that it's a piece of cake when they've had years of on the job training in doing this kind of thing, something that your average, say, accountant would not have. Based on your own post comments, I feel that your chance of success in doing this yourself is probably 5% or less. If you botch it, you may permanently brick your TV.

bblondie5's post should serve as a warning that there is always some chance that even if you do you own repairs and do it right that you're still not going to fix your TV.

Gday, I have had a similar problem, namely that the standby light will come on, then when I attempted to power it on, all power would be cut.
I have read the posts, opened it up, checked the capacitors, but they are all looking flat and fine.
Any ideas? It is a pretty old tv (320PX from 2008) and I am not attached to it, but I was looking to use it as a second PC monitor in my study.
Thanks!
