Sounds like The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electro-medical.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
Search the site by type in the "brand name" to your device; in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

My tv screen went completely black


If its worth fixing depends on age of set and what it cost.

The place to begin is someone needs to open the set and check a few things------the click is a mechanical relay coming on and likely going right back off.

The problem could be minor or major.

You might want to begin by calling local shops and see what they charge for an estimate of repairing----should tell you if you want to proceed or move on and replace this set.

2001 Honda Civic Key Green light keep flashing in the dashboard


Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.


To confirm the problem, the basic troubleshooting is required.

My 6 to 7 yr old television suddenly went dead


There is a board that manages the power going into your tv I would check around with local mom and pop tv reapir shops. The board is not expensive its the labor I am not sure where you live but I am sure there are local techs that work on flat panel tv's. They are pretty affordable these days. Most flat panel tv's are rated for 60,000 hrs as there life span. Hope that helps

My 52' vizio will not turn on


It's due for surgery to repair the power supply and or main board. One way or another it is defective but let's try the following couple steps as a work around (works for me)
Try this:
1- press power ON
2- wait 20 seconds
3- press power OFF
4- wait 20 seconds
5- press power ON.
Does it start the *second time* with the timings indicated above or never?

Tv not powering on


as per your statement there is a loose contact in power supply section of your tv. it is 1oo% sure that allthe parts are ok as tv runs ok when it comes on. but you will have to call tech. as without knowing technology it is dangerous to open tv due to high voltage.
