Have a LG 55ls5700 tv that doesn't turn on but the red standby comes on and when i press the power button it starts to blink


Does the screen quickly blink on and then off? Does the standby light slowly blink twice and then go out?If these are the symptoms then it is probably a bad led backlight strip.This was the fault with my lg 47ln540v led lcd tv.I have written this up in a previous post more comprehensively.Hope this helps..

My Toshiba 55SL417U will not come on. The led light blinks, but screen remains black. It is no longer under warranty. Is there something I could do to fix it?


Hello
The main board of your TV should be troubleshooted. It is a very skilled work, and you must have sufficiant knoledge in electronics and expereince to work with digital printed circuit boards. In most cases, the repair to this board will be immpossible, and may replace it as card basis.
This is the picture of the main board to your tV.2_4_2012_6_28_32_am.jpg

Sound like the power supply board has gone out .Unplug the tv for 2 or 3 minutes and plug it in again and try to turn on. Some times they will come on .But It sounds like the PSB is going out .

Had continous red blinks on lamp led replaced lamp and ballast, now have 5 blinks on power led still no picture or sound



Try connecting the TV directly to a different wall outlet and check. If the issue persists, try power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. If the issue persists, then the TV requires service.

JVC LT-32P679 Blinking Power Light, Automatic Shutoff


1. Hold [menu] and [vol-] button on the side of the TV
2. while holding these, press the [power] button on the side of TV (NOT remote)
3. blue light comes ON and stays ON
4. wait 10 seconds then let go of [menu] and [vol-]
5. wait another 30 seconds and some type of picture should appear

I think this is right. I got it from the JVC call centers guys so sorry if I missed or messed up a step.

Sony KDF-E55A20 No picture or sound


The little flashing light down on front of your TV will tell you the problem by the color of the light or the blinking intervals, this is the reason you can not turn it off is telling you something. The manual should have a section dedicated to this part, most likely is the bulb, the bulb is easy to access generally hold by one or tow screws you can pull it out to verify the integrity of the bulb. Then again check the LED light before anything then you go from there.

Blinking Red Power Light


It sounds like the horizontal (H stop) and vertical (V stop) has gone bad. Check Cap 515 and 516. IC1509, Q1505 and the jungle IC, IC206. You can also bring up these fault codes on-screen to see a list of the problem numbers with the abbreviation of the problem and the number of times this problem has occurred. This is slightly different than entering the service mode. To see the diagnostic screen, press the following buttons: Display, Channel, 5, volume Minus, ( not plus ) then Power. This brings up a screen with a list of the problems and number of times they have occurred. Each of the problems named, are abbreviated as, "OCP", "OVP", "V STOP", ETC.
