First of all did the set get wet? If so, It needs the boards washed Immediately! Spray boards with windex soak em up. Need to remove all salt deposits and minerals or the boards traces will rot.Then rinse with distilled water let dry Then you could save this set. check this site They rebuild assorted stuff cheap. www.irionstvshop.com

Sony kdl52nx800. hit by lightning. Replaced main fuse. all outputs of power supply are solid.only red led.. replaced main pcb. tv will start to come on . screen flashes one second. green and yellow lamps...


You might wish to unplug the TV for an hour or more. If this power reset does not allow the TV to turn on component failure is indicated. These sets are assembled using the wave soldering process they are known for having cold solder connections.

The safety circuitry shuts the TV set down or will keep it from turning on when it detects a problem. This model of TV has over 2,000 parts, which includes millions of transistors inside the integrated circuits. The capacitors will change value, leak and become defective. Resistors will change value and burn. Diodes and IC can go bad.

This may have a domino effect and cause other parts to fail. Replacing one defective part may make the TV operate for a short time but the part will fail again if the parts that caused the failure to begin with are not replaced.

The only way to know for sure which parts that are no longer within factory specs and for a proper repair all the electronics must be diagnosed by someone with the correct electronic test equipment specifically designed for TV service and the skills to use the test equipment. I wish I could tell you there was a quick fix or button to push that would fix the TV but that is not the case or the solution needed to get the TV operating correctly.

Hi,

check power and y sustain board is a relative large board on the left or right side of the TV display..

the problem of overheating in the power supply board of the TV.on the power supply board of the TV there are few capacitors and IC.any of this ic is got short or may be weak.so due to this when you start the TV the current passes from electric outlet to the power supply board of TV.but when the current passes from that weak/faulty part at that time current gets stopped or slow and the board overheats and TV shuts off.

This is a common problem faced by many other users too.the possible option to solve this issue is to check the power supply board by a meter and continuity tester and replace the faulty component on the board which is short due to which power supply board is getting overheated.its bit technical job but yes its not at all a costly repair to do or get it done by the technician. for required parts it can be easily available from local electronic hardware shop.

I hope this will help in solving the problem.....

The picture goes blank after I turn on the power. stays on for about less then a minute but the sound is fine. this a small 19 0r 20 inch screen lcd tv by memorex


Hello,

Problem is in either power supply or the Y-Sustain board.

The Y-Sustain is a relatively large board out of which go connections to the side of the display; it's therefore closer to either the left or the right side of the display, has at least one rather large heat sink on it and fat power cables connecting it to the main power supply.

Often there are fuses on that board - one or more. Check those.

if they are blown you can try to replace them, but expect them to blow again - usually the whole board needs to be replaced.

I hope this will hear to solve the problem....

How well does the Fish Hunter 280 do in the Ocean?


I don't think it would do well at all, Ive taken my Fishhunter 360 in larger lakes with waves and came close to tipping quite a few times with all the gear, motor,etc. Try an inflatable with a v-hull if the oceans your thing!

Causes of Tsunami


Tsunami is a Japanese word meaning ''huge wave'' that refers to a series of large ocean waves. It is caused basically due to underwater earthquake, Richter magnitude exceeding 7.5 to produce a destructive tsunami.


Concept can be summarized as follow:


The earth is constantly moving on large tectonic plates. When these tectonic plates moves past each other, collide and/or slide under one another an earthquake results. This is what happened with the recent tsunami that devastated Southern Asia. A massive earthquake in the Indian Ocean measuring 10.0 on the Richter scale jolted the seabed causing the sudden displacement of a very large volume of water. The earthquake temporarily produces a fluctuation in the mean sea level of a specified area. Waves quickly form as the displaced water tries to recapture equilibrium by filling the vacuum that was created. Tsunamis are a series of extremely long waves that are created after a large volume of water is displaced. The amount displaced must be significant enough to create waves underwater in the vast ocean. Waves are formed as the displaced water mass moves under the influence of gravity to regain its equilibrium. The larger the displacement, the larger the wave generated.

Kde37xs955 sony with sound but no pic


This tv uses two power supplies. Do you hear a high pitch squeal? If so replace the small G power supply. If not make sure fans turn freely and finally change the large power G board. Look for obvious hot spots and swollen caps before buying board as the small bd. is approximately 129.00 and the large even higher. Part numbers on stamp on each board.

Hope this helps: Sam Farrell

Humminbird NS25 GPS


This is a common problem on lots of boats with any brand of electronics. Most likely it is being caused by a bad crimp in a wire connector, or by having too many connectors on a terminal in the power supply bus. Start at the power supply source and ground and replace any butt or terminal connectors with high quality heat shrink connectors (such as Ancor). Make sure that the connector is the right size for the wire.

On Humminbirds the problem could also be in the swivel mount that holds the power and data cables. The cables should be held in place by a metal bracket which is located under a panel held onto the swivel bracket by to small philips head screws. If any of those components are missing, the plug may be loose in the socket which could cause it to disconnect temporarily when the boat hits a wave. While you have it apart check the plug and the socket for corrosion.

I hope this helps. Please contact me if you have any more questions.

Blank screen on sony trinitron tv


The problem with this model is the large parts due to poor wave soldering. Locate the transistor Q605. Using a small wattage soldering iron melt the solder and add a little solder to all the large parts in the area. Small wattage = 15 to 30 watt. Stay away from the surface mounts they are not the problem. I resoldered the following: D647
Q605 C690 D645 D620 R691 Q691
These parts are located on the main board, the one the power cord connects to. Carefully press the clip on the left side of the board (as you look at it from the rear of the tv) carefully pull the main board back and out of the rails. You will find the parts on the right side of the main board about 2 inches over 2 inches down.
