Samsung LNT3242H Television - Answered Questions & Fixed issues

what is the make and model?

Go to settings in menu and Reset to Factory settings...Hope this works

Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electro-medical.blogspot.com/ http://homenol.blogspot.com/ http://electronicshelponline.blogspot.com/ If blinks continue without any pause, the main board is faulty. Search the site by type in the "brand name" to your device, [Exclude the model number] in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

Hello Compgeek09, It appears that one of the CCFL lights might have broken behind the screen and that is why the TV would turn on for 1 second and goes off after. The noise you are hearing could peaces of shattered or broken light and you would have to remove the screen and to be able to fix it, if you are up for the challenge. Let me know if you required further assistance.

Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electronicshelponline.blogspot.com/ To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

Fault to the main power supply regulator section. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electro-medical.blogspot.com/ http://electronicshelponline.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size. Never think, that a TV works one only with some capacitors. Some people thinks so.

Ask them to replace the t-con board. It could be a defect one.Good Luck. Serge.

If this is related to no picture or sound, then the power supply in many of these Samsung's TV's have under rated capacitors installed causing them to bulge or fail. If you are out of warranty and cannot fix it yourself, get someone who understands electronics to verify the problem and fix it.

Just for added clarification, remember to use the "Air" connector at the back when using an antenna and the "Cable" connector for the cable box or wire. You can download the manuals from Global Download Center for final setup.

check all your input cables & sources.If that doesn't solve the issue you may need to replace MAIN PCB, several part numbers listed at this site (correct part # dependent on your complete model#) https://www.encompassparts.com/model/SMGLNT3242H/_/_/Samsung/LNT3242H/LCD_TV also check this site: http://www.shopjimmy.com/catalogsearch/result/index/?q=lnt3242h&tv_brands_select=Samsung&tv_models=Samsung+LNT3242HTX%2FXAA Again, you will need your complete model# for proper part# & pricing.

It is not predictable about which component/s might have damaged due to lightning. Contact the authorized service centre for Samsung. Gopakumar Gopalan Google

Main board fault. Contact any service technician. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" will make surf easy. http://electronicshelponline.blogspot.com/

Did you fix it? How? I Have the same problem,,,

THat is something you will have to take to a shop to have fixed unless there is someone near you that does in home service.

Check with Samsung, that unit should be covered under the class action lawsuit settlement regarding bad power supplies that were install in many Samsung TVs. You can get additional information and contact numbers herehttp://www.ccl-la.com/blog/index.php/samsung-has-reached-a-settlement-in-class-action-lawsuit-over-faulty-tv-power-supplies/

Whenever a television starts doing this the motherboard/main board and or power supply is usually at fault. The power supply can usually be rebuilt for around $150 depending upon the knowledge and skill of your local television repair shop. To replace the parts is usally more expensive then it would be to purchase another television ($300 and up). Are you sure this is the model number of your television because this model number is not for a CRT television. For troubleshooting you can unplug it overnight to try and power cycle it but it sounds like your problem is beyond doing any type of power cycle to get the television back going again. It would need the repair shop or to be discarded for another.

Dave, please note that the part number of the replacement T-con should match word for word with the part number of the board in your set or there will be problems. If you are sure that you have purchased the exact replacement but it still does not fix it, I am so sorry to tell you that its the LCD panel itself thats faulty. The Panel costs nearly as much a new set and the best thing you can do is to sell the working parts of the set on ebay to save on a replacement. The last thing I want to advice people is to throw away their sets, but here we do not have a choice. Sorry!

Hi, Check that the buttons on the remote and tv that they are not sticking. also replace the batteries in the remote. If it still keeps doing that bring it to a repair shop. Good luck.
Check the obvious that it could be.

Problems with these TVs not turning on are usually capacitor related. Take the back off then look on the power supply where the power chord goes look at the fuse next to the plug. See if it's physically dark if so, the fuse is most likely blown and you should just look up the board number on E-bay for a new power-supply for a more costly, but easier fix than a repair shop. While the back is off, look for capacitors that are puffed and see if they need to be replaced. There are usually 2 caps by a heat sink that look bulged.

This is the inverter board if this is the case. Try swapping one at a time because usually only one is bad.

go into your menu and click on sound options/volumn and change the output to tv speakers[or receiver if you are using one]. More than likely a button was accidentily pressed that changed this.

Please take a moment to rate :]
Hope this helped
