My Samsung LCD #LN52A750R1FXZA will not turn on. It keeps clicking like it will come on but doesn't. I have read it could be the power capacitor. Has anyone had the same problem with this model? If so, how did you resolve?

SOURCE: samsung lcd tv keeps clicking but won't turn on

ur tv needs a new ip board u can remove the back panel and its the center main board it'll be obvious to plain site being its the only unprotected board in the tv. get the model number from the top left of the part then go to enter the part number order the part.this part is only about $130-$150 dollars and ur tv should be as good as new. the ip board is a simple fix just six screws around the board and seven wireharnesses just remove insert new part and and reconnect wire harnesses to correct slot that u removed them from screw back down and ur all set no big deal. dont ask samsung or a repair man they'll just screw u over and throw u around about ten differetn loops. not gettn a straight answer other then bring it n and charge u about $600 to fix. i see alot of people have this problem so there u go simple fix guaranteed. u r welcome.

Samsung model ln52a750r1fxza start to power up chimes and then clicks off then repeats itself - unpluged and pluged back in just repeats without me doing a thing.

Had a similar issue with my set LNT 4061FX/XAA. After doing some research on line I found that Samsung company had an issue with some capacitors. There is a group action law suit. I found that my set was included. Called Samsung and they were extremely nice and helpful. They called a local repair shop, gave them a invoice charge #, and the repair shop ordered parts needed for me. I took TV to them (althought I was offered home repair), and my TV was fixed for "FREE"!!! Got it back and working better than it had in years!!!!! Thank you Samsung!!!!

My LN52A750R1FXZA LCD TV will not come on, just clicking sound

I would suspect faulty power supply capacitors, check for any with bulging tops.

My Samsung TV LN52A750R1FXZA is Power cycle on its own

Sounds like a bad main board, but you will need to have the set diagnosed to make sure.

My LCD TV Series 530 keeps on blinking and would not turn on. why does it keep doing that?

I've experienced similar issues with a 42" Samsung LCD TV. From what I've read online, I believe it could be a problem in the circuitry of the power supply. Apparently, Samsung used under rated capacitors in the power supply and the result is a turn on delay or blinking on and off. If this is the case, then the capacitors would need to be replaced to fix the issue.

Hi - My Samsung LNT5271FX 52" LCD TV won't turn on. It just clicks over and over and over, but never turns on. What's up? A relay?

This is a capacitor problem. Several Samsung models have bad capacitors installed on the power supply boards. Samsung currently offers a recall fix for this and other models. Call Samsung direct to see if your TV qualifies for this one time fix. It is a free fix, so if the person on the other end doesn't have a clue, ask to speak to a supervisor or hang up and try again.

Samsung LCD LA40R81BX/XFA TV doesn' switchon/ keeps clicking

Nothing to do with connecting the TV to the stereo, more likely you are having power supply failing, the clicking sound is from power relay, the power supply may have unstable DC due to bad DC filter caps, bad solder joints or loose connections.
If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

My samsung lcd tv is clicking and wont turn on

Its a common problem with many Samsung LCD TVs. We had the same problem on our Samsung TV. Based on some info on the net we called Samsung Support department ( 1-800-SAMSUNG). After describing the problem and mentioning that I have read on the net that its a common problem, representative asked for the model number and serial number of the TV ( I read them to her from a sticker on the side of TV). The Samsung Rep acknowledged that it was a common problem for my model and few other LCD models and they were fixing the problem without any charge to customer eve though TVwas out of warranty. She took the required info and gave me the ticket/transaction number and forwarded it to a local technician. Technician called next day and setup the appointment with us. Technician came within the 4 hr window that he had promised and changed the faulty capacitor on the power board and was done within 10 mins. Samsung rep had indicated that the technician will determine if the issue was with capacitor or not. If the issue was something else then tecnician will charge the regular service charge to fix the issue.
