The issue I have with my tv is similar to the other power down issues. I press the on button and you can hear the relay turn on, tv charges up but no picture and then you can here the relay turn off. The reason the tv is doing this is because it was disrupted by a lightening strike outside the house. I placed the tv into diagnostic mode and it spit out the 2-4 code. I checked the 9 fuses on the two boards and they all passed a continuity test. I then started to check the 3 boards for any visible failure and I think I found the cause! A failure of the PNP 12v switch labeled Q9A20. Here are two pics. Your technical guidance would be appreciated. do you think I can just soilder this again or should the component be replaced? I looked and found radio shack sells a similar component but i am not sure if it is the same. Thank you for your time.

My TV has the same problem. At first, it was an issue with the button itself, somehow some gunk got down under the button and kept it from pressing down all the way most of the time. A few days after we fixed that, it started to mess up again, this time it was an issue with the way it transmitted signal to the TV.
If the button being blocked isn't the issue, replace the batteries. If the batteries aren't the issue and you don't have a soldering gun, then you'll need to purchase a new remote.
I bought one from walmart for ten dollars and it works just fine for basic use.
1.Check the device's battery level for at least two bars of strength. 2.If the battery level is low, charge the battery. 3.If the issue is not resolved, remove the back cover. 4.Remove the battery. 5.Wait 10 seconds. 6.Press and hold the W key. 7.While pressing down the W key, re-insert the battery. •The device restarts and after approximately 15 seconds, the 'Recovery' screen appears •Release the power button but *continue holding the home button*, for another 30 seconds. Step Thanks
You can try to reset the video settings on the ps3. If you have had it hooked up to a hd tv it may be defaulted to the HD signal and need to reset the video output to be the right format for your tv. To do this simply hold the power button down when you turn the power on to the ps3. You will press to turn the power on and then keep the button pressed until you hear the unit make a beep (about 3 - 5 seconds) then let go. This resets the video settings to match what the unit is plugged into currently.
You can also try a factory reset, I have that listed below if the video reset fails to fix the issue.
This will wipe all the saved games and data from the machine but I have found it to correct most issues with the ps3.
You will need to push the power button to turn on the unit, but keep the power button held down for about 30 seconds. You will hear a beep (resetting the video settings), then 2 more beeps. After the 3rd beep you can let go of the power button and it should take you to the set up screens like you just got it out of the box.
You will lose everything you have saved doing this but it seems to make the system run just like out of the box again. If this does not fix the problem then it most likely is a hardware issue and may need serviced or replaced.
Check if the issue is with the TV by connecting any other device.
If the issue is with the TV, then try resetting the TV to the factory settings by performing the below steps:
To reset the TV, turn ON the TV, then while holding down the UP ARROW button on
the Remote Control, press the Power button on the TV front panel. The TV will
turn OFF and then turn ON again. Then release the UP ARROW button to complete
the reset procedure.
If the issue still persists, try Power resetting the TV.
To Reset the TV, please disconnect the power cord for a short period of time
(approximately 1 minute). Then, reconnect the power cord and power on the TV.
If the issue still persists, service is required for the TV.
The clicking noise that you are hearing is actually the power relay. Normal operation by either the remote or the power button on the front panel, you would normally hear a soft click just after the press of the power buttons to turn the unit on or off. When you initially plug the unit in to power, you will hear the same click noise. Being that you are hearing it all the time indicates a failed relay. TV's now a days, or at least ones built during the last 15 - 20 years have different Printed Circuit Boards (PCB). There are PCB's for power (which youre dealing with now), sound,video and so on. The PCB that you need to repair your clicking issue will run you about 80 U.S. dollars for the part plus the average going rate for repair from a qualified service tech. You could purchase the part from Thompson Consumer Products repair and fix it yourself, but be aware, there will be no warranty on the part itself unless an authorized tech does the work. Located on this PCB is the power on/off relay, fuse, usually 4-5 connectors for power to different PCB's (depending on model and features). Now depending on how old the TV actually is, you may want to invest in a newr set, the reason why I say that is, is because the new power unit may and can overload the other boards and cause damage to them and now you have a new problem to deal with( along with more money being tossed down a hole.
Hi, the relay is getting a command to shut down because there is a short somewhere in the set, if you have a volt meter you can check the "chemical fuses" to see which one(s) are open and that will tell me which circuit has the short in it. be advised these are not glass fuses so if your unfamiliar with what a chemical fuse looks like you will have to look on the power supply board for a small rectangular body device with a designation printed on the board "Fxxx". check these and let me know which ones you have failed and we can go from there, BMW Rider
