SOURCE: LCD TV won't turn on, Screen and Standby light blink

I had a similar problem which I have partially solved. The power light flashing could be due to a shorted electrolytic on the power supply board but in my case it was a shorted IC on the main board, the one with the input connectors. The IC marked 7001 shorted and got hot enough to melt the plastic. Replaced it with a new one from Mouser. The supply measured on the end of inductor 5001 farthest from the IC reads 12V now. This is a surface mount part and has a pad on the bottom that may be soldered to a pad under it. I had to cut the IC apart carefully with a Dremel cutoff wheel to remove it. That fixed the problem with the light and the remote now turns the TV on and off so the logic is working.

I now have the problem of the backlight not turning on. The driver board, the ones with the transformers, are made by Intechwave, the only info I can find is here: http://www.peopleworks.co.kr/kor/product/product_list.php?intDivision=4&intClass1=16&intClass2=41

This a 45kHz RF driver and it is not starting. If I can figure out why I'll post it for all the people who reported slow or no turn on of the backlight. These boards should have 24V between the red wires on the connectors and ground, as mine do.

Hi I am Vortash .. usually the problem is aerial the digital aerial is diffrent to the old UHF aerial and you will need to change it should you still be using it .. from what you say the set is working fine and you didnt do anything wrong .. it is just like unlike the old annalouge signal where you would get a picture even if it was poor .. digital systems are less forgiving of low signal and just blank the low signal channels out .. to check for sure if your not already , use a set top aerial.. and move it about to find the best signal if you get more channels problem found so update your aerial ( Or stand the kids in the corner holding the aerial ?LOL ) I hope this helps and that you will be on freeview soon .. oh and check with the ITA that your area has full Freeview transmissions .. there is a 24 hour call line .. on 0800-40 85 902 and they will give you all the information you will require hope this helps Regards Vortash

SOURCE: 20" lg LCD backlight turns off after about 5 seconds of use.

First, check the power supply for the backlight. It's usually a 24 volt supply. Look for swollen caps. If that is ok, go to the inverter board and inspect for damage, ohm out the inverter transformers. Last is to test out the lamps seperately with an external inverter. If a lamp goes out this way, it is bad and causing the whole backlight to go out.

Why does my TCL tv stay dimmed and very dark screen? I've reset it and everything?


Back - light problem. 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.

Technika tv


If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

We recently got a new LG 42" 1080p HDTV and occasionally the screen goes dim/gets slightly darker while we are watching shows. It is not the show as I have tested the same spot the dimness occurs...


It can be the auto-contrast is doing its jobs so LG can claim that the TV has really high contrast ratio, also try turning off auto brightness feature off. It gets real bad when the scene has dark back ground such as the dark sky with stars, the TV will really dim down to give real black sky but at the same time you can barely see the stars on the screen, LG is not the only one with this design problem, VIZIO and other has the same problem as well. If you Google your model and search for review you may see that you are not the only one with this problem.
What is the exact model of this TV.
Please let me know what you find.

Toshiba 22LV505 TV-DVD:


Check the DC filter caps in the power supply first. Check the 24vdc (or 18vdc for this 22" model) to see if it goes away when the screen goes black.
There are main AC fuse, backlight inverter fuses, T-CON fuses.

The screen comes on fine but then dims????


Hi there, I have the same monitor, but mine has a broken screen. It's probably the inverter chip, that makes your contrast bright.

LCD TV Acer is fading out


If what you are saying is the screen shows up and then goes dim or starts dim, and you can see a dark image (maybe reddish in tint)...

Your problem is a bad CCFL (Cold Cathode Fluorescent Lamp) at the top of the LCD panel.

You can find many websites that sell these parts, but make sure you have the right model.

If you feel comfortable with working on components, you can replace this part yourself. Otherwise, you may want to pay a technician to do it. Make sure to get a fixed price quote before authorizing the work.

Here is a website on LCD repair for laptops, but it the same principal for most LCD displays (TVs).
