SOURCE: LG LCD TV Standby Light Flashing Red Continuously

I have had this same problem twice in the past 3 months. So far both times I've been able to get it back after a week or two. I'm not sure what works, but unplugging and detaching the antenna and cable and waiting a few days seems to be the key. In both instances, I unplugged it for a few days then plugged it in for a few days and repeated the processes until I eventually got the steady red led. Both times prior to the red led the led would flash red then green and make a clickiing noise for several hours before I was able to get it working again.

There is probably a bad capacitor on the power board, I had the same thing happen to my 42LB1DR after 2 years. T.V. would turn on and white power light would blink, no pictue and no sound. If your'e a diy'er, it is not that hard of a fix. Take all the covers off of the back of the tv(UNPLUGGED!!!), then look at all the capacitors on the power board. lcd_repair_4_bad_capacitors_lg.jpg
These are the capacitors, look to see if any of them appear to have a bump on the top of them. They are supposed to be flat, you can also tell if one of them has gone bad if there is an oily substance on the metal cover that was removed. If one of them is in question, carefully remove the board, and take it to an electronics store to have them sotter ?sp on a new capacitor. It ended up costing me around $40.00 to have this done. Good luck and if you are not comfortable trying this, than take it to a repair shop, but I was quoted around $450 to take the T.V. in. No Thanks

Whe you press the power button the TV led have to blink several times and the it have to change to blue, meaning Tv is on.
If you press the power button and the led start blinking and goes off, then you need to replace the mainboard because it is damaged.

Bye

The flashing light indicates a short circuit inside the power supply circuitry. This type of repair is not a DIY without a multimeter, desoldering iron and hand soldering skills. I repair these power supplies, if you need further info write to jah2mil@hotmail.com

SOURCE: samsung lcd tv le40r8. tv will not switch on.

The problem is the mainboard tried to turn on TV but failed due to internal circuit problem. Normally, the power supply board is malfuntioned.

You either have a problem with your power supply board or main board. I would start with having the power supply fuse checked as well as the power supply board!

TV won't turn on power light flashes 10 times


Switch off the TV from remote, then switch off the on/off button on the TV, remove the plug pin from the power outlet. Cool off for 48 hours and then retry. If nothing works, better refer it to a qualified service technician.

TV won't turn on


It sounds that, the memory IC to your TV has damaged. This IC can be located very near to main system control IC. A very small one, with 8 solder terminals. Even though it is very small, function of it while the TV works is great. The work is a semi-skilled one, and you must have some knowledge in electronics to proceed.

My LCD tv turned off and then flashed a red light and then I unplugged it and then tried to turn it back on and it didn't it just had a yellow flashing light. Then I left it unplugged for a little bit...


your power supply need to be check. Some of the capacitor needed to be change for there where worn out or blown on top. The voltage that he need couldn't be attain so the capacitor need to be charge longer. this occasionally happen to all switching power supply

Tv wont turn on


Hello Charliebigwh, hi technically your monitor's power supply has a problem, this is either your switching regulator does not work or there is a short in that section, If you want to do it your self, need to replace all large value, and or high voltage capacitors(especially the capacitors with its top is bubbly), need also to replace the switching IC, and power transistor.

Have it checked by a technician if you cannot do the work.

LG flat screen wont turn on. Ive tried unplugging from wall


The flashing light indicates the TV is in protection mode. Most likely logic board. Not sure what your model is but its usually the board that has your digital inputs in it ex HdmI etc. Post your model and you should get some one to post more info Ex ( LG XXX has a common problem with tuner board)
