    Grandson dropped a key in back of TV (LTdvd20 DYNEX}. Suspect it hit something on the power supply cca. I measured the voltages at the 2 connectors and all appear ok except I do not know what B-adj and B on are suppose to be. Only getting 5vdc on 3 outputs and 4vdc on the other. Should it be higher?

    When power up the tv it flashes dvd mode on the lcd and then goes black. Sound is ok. I can get the mode to change some times when pushing source at turn on. DVD player runs and only get sound from it. No video. Green power light comes on and the mode displays briefly,does not look that dim.

My LG 42LH30 gets red power light but wont turn green?


Fault with main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Daytek 46" LCD TV.. When


Hi,

Your power supply board is dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

Good luck in solving the problem....

My power light on hitachi lcd is flashing red and wont turn green using the remote ,,,turned of to standby now wont come back on,,just flashes red light on tv...


Sadly to the end I can now explain the "problem" of my question by myself ...
Because I'm was not sure if I can handle the "problem" by myself I gave the Screen to a technican at our City with all the Information I found until this point (By the way my suspicion was the defect of something at the power supply unit). Two days later he gave me a call with the information about the error: An error at the power supply unit - spare parts => 50€, Work => 200€).
Unhappily im not yet got at soldering on screens, but for 250€ i would have made a good course for this (and if I can establish i will learn it).

So now again a bit more objectively:
Error / Problem:
TV - Step 1: Power Off
TV - Step 2: Stand-By
TV - Step 3: Power-On
TV - Step 4: Short flashing picture
TV - Step 5: Reverse to Step 1

Solution:
1. Find the defect Fuse/Safe/...
2. Buy the Spare part at eshop2.euras.com
3. Change the parts -> et voilá

Hopefully I could have been a little help for someone.
With kind regards,

The power supply most likely failed on your LCD.
