    tv stays on for seconds and turns-off ---- what is going on

  • Anonymous Aug 29, 2008

    Same problem - turns on for about 3 seconds and then shuts off. Took it to a tv repair shop - they told me the entire panel had to be replaced - $400. No thanks - the tv only cost $275. Should i try another shop? Spent $50 on the first one.

I had a similar problem and I believe the problem is with the high voltage circuit and ccfl transformers. If you know electronics you may be able to find the chips that provide the power input to the CCFL transformer (I had two transformers and 4 FET's). You will also need a micro soldering station and excellent soldering skills to replace the flat packs (SMT). Hope this helps.

My screen turns off and on... stays off for several seconds and thens turns back on... does this several times, then wont turn back on until I unplug the power cord and replug.??? Unit is about 1.5 yrs...


Before we start taking things apart, lets try your simple remove power plug routine and power system back up. Also, please try your unit on a few different channels to see if your problem continues on each channel. Your Main Board, Power Board, T-Control Board are suspected problems at this time. Press and hold the power button for about 15 seconds, the unit should power down by itself after you have powered it on. If it does not, then do not be concerned. Let me know if the problem continues. The first link below will bring you directly to the troubleshooting guide if you need to continue forward with the same error.

When I turn on my LN32A450 TV it flashes to black screen for a few seconds for the first 15 minutes or so. I have tried unplugging for 30 seconds as mentioned in the manual but no help. After it warms up...


This is probally a fix for a repairman. Probally a bad video card or power supply board. It is probally not going to be cost effective, You are probally best off buying a new one.

MONITOR ISSUES


There could be a problem on the monitor itself if it frequently turns itself off, try to unplug the VGA/ DVI cable and check if you can see the self test feature. If not, the monitor needs to be replaced. If you are still covered by the warranty, just call dell and they will replace it for you. Hope this helps

I have a samsung 15 inch LCD TV. When I turn the


kcs36dd, Lcd TV's also have, just like LCD monitors, an AC to DC voltage power supply. It is called a "switch-mode-power-supply" and generates the DC voltages required for all the other important electronic circuits inside the unit. 98% of all 14" to 22' lcd panels have backlighting provided by "cold-cathode-fluorescent-lamps" (CCFL) that produce WHITE LIGHT so you can see all the pretty colors that the glass LCD PANEL produces on the screen. The INVERTER circuit requires 12vdc to 20vdc from the SMPS to convert into 500 to 1000v ac to light-up the CCFL's. IF the SMPS detects a FAULT CONDITION with itself or the INVERTER it will go into what is known as FULL or PARTIAL SHUTDOWN MODE to try and save itself from a catastrophic, nonrecoverable failure. e.g. sparks, smoke, fire. lmistyrel on aim.com I could give you more assistance if you had provided following informatiom.
1. How old is the unit? 2, Approximate total "ON" hours unit has? 3.Has unit failed within the WARRANTY period? 4. Will SAMSUNG do a cash+old unit swapout because of PREMATURE FAILURE? 4. Do you know enough to do a unit TEARDOWN and inspection to possibly determine ROOT CAUSE of SMPS/INVERTER failure? 5. Can you handle a soldering iron and solder to make DIY repairs to unit. 6. Since your unit is just a little more complex than a LCD MONITOR, have toy viewed on YOUTUBE short video clips of "LCD monitor disassembly" or "LCD monitor repair" for the most common cause of BLACK screen complaints? If further assistance is required do additional post to original. 12fixlouie aka louie12fix on fixya

Screen goes black


This indicates the LCD inverter in the display is dead. If you have any experience with computer repair, replacing an LCD Inverter can be easy enough; However, it may not be worth it for a 15" LCD; replacement inverters can cost anywhere between $15 and $40 - a decent used 15" LCD only costs about 40 bucks these days...

Monitor show picture for a few seconds, then turns black


It sounds like the power supply board on your monitor is failing. If it's still under warranty you might be able to get a replacement from the manufacturer - if not, you might be able to have it repaired at a computer or TV repair shop.

My monitor turns itself off


If it's only a few months old then send it back under warranty.
The fault you have is the inverter circuit.

Hope that helps. =)

Sounds like your problem is hardware and lies with the port on your PC, this may be due to a bad driver, or bad port! Sounds like you have tried everything else!
