Well if it is a capacitor or an onboard component you need a technician to do the job usually you get this job done for a couple of hundreds dollars, if the technician must replace both convergence ICs, for example the charge is $250/$300. If you call a repair shop in your area and describe the problem they will give you the exact amount.

Bought kids kindle fire. Initially came up with kids apps but now it shows up as our fourth kindle with our apps. Kids apps disappeared. Help please


Maybe you used your email address to register the Fire, if you did it will show your apps. De-register it and set the kids up their own account or an account in the spouses name and just put on the kids apps.

I have a Samsung TV model UN50H6350AFXZA which has sound but no picture. Backlights work. Replaced t-con board with new one, but not fixed. What next?


Main board. T con board is only involved with video issues. Main board goes both ways and since you already replaced the T con board that is your only alternative. U got backlite so inverter board is good.

I read somewhere that we should be doing more creative play with our kids but it seems to me that kids do too much playing these days and should be learning more. Do our kids play too much?


I really disagree. I think our kids today have become too fixated on quick fix electronic games, computers, gadgets etc and I don't really count that as play. In terms of learning, the academic demands on our kids time has increased dramatically over the last 2 decades, so it seems like we are stuck between 2 extremes and I think we need to reclaim some middle ground, where kids re-learn how to enjoy creative play that doesn't involve electricity.

I have a Vizio 50"


Good day!!!

That problem is usually cause of bad inverter board or T-con board also there is the possibility that you have failing capacitors....

If your TV is totally black even back-light the problem is inverter board..please try to replace it to fix your TV.


If your have back-light but no image comes out...The problem could be on the T-con board..if that so please replace it...

This is for bad capacitors...

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..

I think that there is only a loosed or cold solder in the t-con board or some bulge up or leaky capacitor in the power supply. Try to remove the back cover of your unit then observe carefully if there is a bad capacitor in the power supply, if you see this bulge up or leaky capacitor try to replace it but be sure to observe the polarity, because this bad capacitor will cause your unit to malfunction this bad capacitor is producing a low and unfiltered dc output voltage. Be sure to unplug the unit before removing the back cover. Feel free to send feed back good day and best regards.

hi,
You can suspect three things in you tv for this fault .. One is the Balck light inverter board And the disply driver ( T- con ) Board. You have mensioned that there is back light when the picture become blank. You have to check the same one more time and confirm that the back light is working perfectly. If you seems the backlight is ok then the problem is with t-con board or faulty electrolytic capacitors in the power supply board . you have to check for any faulty budged electrolytic capacitors in the inverter board and in the power supply board. IF found such capacitors replace the same will solve the problem. If there is no such capacitor found then you have to check the T-CON board.

T - con board is one which drives the pixels in the rows and colums of the LCD panel. You will find this T-con board in the bottom middil side of the TV. It will be coverd by a metal case or an aluminium ( to protect from inerfearence). There will be a connection from the mother board to this board And other two connectionsfrom this board will go to the LCD pannel. There is no repair possible with this T-con board. It should replaced as a moudule. Have added the picture of faulty budged electrolytic capacitors how its looks , inverter board and T-con board.

Replaced panel, mother board, analog board and digital board and still the tv turns on then immediately off. HELP


I had a similar problem with my 42 in Philips LCD HDTV.



Here was the problem. My Power Supply Board had several bad capacitors. I opened my TV (warranty was expired of course) and found four bulged capacitors. Many electronics companies were sold capacitors that failed in 2-5 years instead of 10-20. The capacitors fail prematurely due to a lack of preservatives. Unfortunately, they were installed in all sorts of devices and cause a wide range of failure problems.


Here are some options for you.



1. Have it fixed by a professional $$$$$$$???????



2. Open your TV and find PSB. Check for faulty caps. If you find some (bulged or leaking) bad caps replace the entire board. The entire board costs around $100



3. Remove and then replace individual faulty caps. This takes some soldering skill.



Caps are inexpensive and if you can take care of it yourself it will save you hundreds.



I have a tip/tutorial on this site that may also help. It gives step by step instructions for replacing caps on PSB #715t2432-2. If this is your board you are in luck. It's called: Fixing the Philips Turns/shuts off on its own problem. I'm working on uploading pictures to help guide people though the process as well, so if you would like to view them check it again soon. Let me know if I can do anything to help.


Hope this helps and Good luck.
