    Power on/off light on front of TV goes from red to blue, red to blue. Screen flashes blue but does not turn on. I tried unplugging all night, pushed every button on the TV and remote trying to figure out what happened. All I know is that I was watching it with my daughter who turned the TV off with the button on the TV rather than the remote. A short time later it was noticed the red/blue lights were flashing. What happened and how can I fix this?

SOURCE: My Hisense lcd is lock.

This is how I got mine to work after weeks of struggling just trying to find a new remote (hisense is really hard to contact....).
1) Turn the TV ON. unplug the tv while still ON 2) hold down the "menu" button on the side of the TV and plug it back in. keep holding it down. the TV should turn on with the menu popping up. use the Vol <> keys and Channel <> keys to navigate the menu. go to the Vchip menu, and play around. I'm not sure what ultimately worked, but i changed the Vchip password to 1111, turned the reset menu to "on" and played around with the ratings settings (turning most of them to "u"s etc).
I went through this process several times and finally, the black background behind the menu turned to static. I played around with the channels, and the TV was unlocked. I turned the TV off, and then on again, and the channels showed up normally (no static). and it was no longer locked. I had to do the unplug thing several times, and was getting really frustrated looking for an "unlock code" in the manual (it just says press the button on the remote. so it was not really helpful).
But really, once you can just get to that menu you've made some progress, and just keep playing around with it until something works.
Best of luck!!

I, also, have the Hisense LCD 1504 and cannot turn it on with the original remote. I have to use the ON button on the side every morning. You have to hold this button in for a while then wait a while and presto, the blue button shows on the front and the picture comes on. If it fails to work the first try, just try try again. It does work for me this way. We had this same experience with the TV in our room at a Hotel where we were on vacation and the TV worked fine when we turned it on using the side ON button. It just takes a while for the picture to appear. Hope this clue will help someone.

Your problem involves 4 electrolytics on the power supply board. There are (3) 1000 mfd @25 volts and (1)220 mfd @16 volts. The power supply board is situated in the middle of the set slightly off to the right. It is held in with 4 screws and has 2 small harnesses on it. The 3 1000 mfd in the set that I was repairing were all swollen at the top and when I ran them on an esr meter sure enough they were opened. The 220 actually tested ok but was a little swollen at the bottem so I changed it anyway. After replacing all caps, normal operation was restored. Thanks, Jack from Staten Island

Lay unit flat on table, remove stand and rear cover. When you remove back, you will see a power supply board in the middle of the set.There are (3)1000mfd @25 volt electroltics and (1)220mfd @16 volt electrltyic that have to be replaced to return to normal operation. This is not something to try if you are a novice as you must observe polarity when installing these caps. But this repair WILL return set to normal operation.

Screen pulses white. off and on, lite on front goes from green to red. model is Hisense TL2020


that problem is usually cause of shorted fly-back transformer that give a very high voltage you can find that by hanging all secondary connection of fly-back then power it again then use your multimeter and range it to dc then ground the black prove to the body of your unit test the b-plus voltage if the supply is flickering it means your fly-back is shorted and if the supply is stable it means you have a shorted diode in secondary thank you

Hi, We have a 42" hslc10668phz


generally when you get a constant green light all is ok. these different lights indicate different problems within the tv. so the pattern of lights you mention suggests there is a fault of some kind (is there a troubleshooting section in your manual)? either way it needs to be looked at.

To unlock your Tl2020 with a universal remote just go into the menu and select V chip setting. The password from the factory is four zeros (0 0 0 0 ). Once you get in you will the letter "B" nect to everything. Set everything to the letter "U". Then, turn off the television. The set should be unlocked now. Good luck !
