JVC LT40A320 turns on but no picture. Replaced Power Supply & Backlight Inverter (TV was hit by a lightning surge, would not do anything at first) now the green light comes on but no picture or sound.


Since your TV was struck by lighting, the power supply is the first board that gets affected by the sudden change in AC power.. The main board is the next board due to the fragile components and the excess of voltage that is supplied to it when the lighting happened. Since you have replaced the power supply already.. I would suggest to replace the main board and that should restore the functionality on your TV.

I have a Sanyo dp42740 plasma TV , the green light on front comes on for about 2 seconds and goes off. what is it?


Hi Gray,
Please try giving 13V from external source. When we exhaust all the options of changing boards we try such things to get the set working. I hope it helps.
Good luck

In morning to turn tv on hit button wait 5 min. lght starts flashing then you can turn tv on


Fault in the main power supply regulator 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. Surf the site with patience. Pull up older posts.

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.

Flashing timer light on a mitsubishi wd-57733


Good day!!!!


That problem is usually cause of faulty capacitors on the power supply board..

Just follow this instruction to fix your TV..

1. Open the back cover of your TV.
2. Look at the power supply board..Its normally connected to the power cord..
3. After that,,try to look at the actual image of capacitors if it is bulged on the top so that you can easily determine the bad capacitors..
4. After that,,try to replaced the bad capacitors using soldering iron and soldering lead..replaced the capacitors only with the same type ratings and value..
5. Some of the capacitors not bulged so its better if have a capacitance meter

Red light flashing, no picture/sound!!!!


HI, this unit has 3 main fuse links on the main board that may be blown. the fuse links should be check before you move further into the diagnosis stage. once you have checked the fuses and they are still in a working state, this will confirm a power supply board failure. this board provides and regulates the current flow and distribution of it throughout the entire unit. If the fuses are fine and the power supply board is damaged, the green light will come on briefly then, the main control will notice that the power supply is not functioning properly. Once the main control board senses an abnormal current, it will shut down the TV rendering the red light warning. The list of fuses to check are below. Remember, if they are fine and working, the issue will be the power supply board itself and, it will need to be replaced.

FUSE CHECK LIST--

3A 12v- fuse----(242208600623)
SM 3A 125v-fuse----(242208600657)
500 MA-fuse-----(242208611092)

The green light comes on then turns to yellow.


if you look at the capacitors on the boards you will find several of them that are domed or blown, these are the most likely cause of the problem. you can find replacements for any capacitor online at electronics supply stores, like radio shack but don't try them they don't supply enough different types. you can also find examples of blown capacitors by doing a search for "blown capacitor image" on any web search. unsoldering these bad caps and replacing them with identical values like 220uf (microfarradys) and say 25 v(volts). these caps have a + side and a - side the caps are marked and so is the board. hope this helps.

Won't power on


my d52w19 chassis itc222 as posted most of the time wont turn on and the green light flashes three times every time it makes a small noise. sometimes it does turn on and you hear a little pop and the tv fires up.  latley there is a really high pitch noise that will slightly change pitch if you move the tv or put slight pressure on the top or botttom rear part of the chassis. thanks for the help as I have seen that this has been posted before without mention of the high pitch noise.

Pover up trouble


sounds like something is drawing down on your 12 volt supply drives or on board regulators. Try it without the drives connectged, and see if you can get the system to boot up(you'll just get a notice that your drives are unavailable, but you'll already know that, right?

got backup for your Dell?
