Facing TV Problems? Ask a TV Technician.
Thanks for details, TV symptoms that you had points touch function board or main processor board failure.
Please check following link to view touch function board (where control buttons are located on TV) and main board..
Please remove the back cover of TV, find touch function board in TV and unplug/ disconnect it, replug TV power cord to see if TV still clicking?
if so then main board of TV would be defective and should be replaced, if TV doesn't click or turn On normally then you got the bad board which is touch function board. Since TV is bit old model so it would be tough to get replacement board so please get the part number off of the board in TV and search/ google it to get price info to order it which also help you to make decision about this TV repair or invest that amount on new replacement TV.
I trust my input will help you out. Please feel free to respond if you have any additional questions.A positive rating to answer would be greatly appreciated, please click on smiley face/star on this page then click submit/finish button so I can get credit on website for my work. Regards,
The link was to show you the image of boards which will help to locate it in TV, touch buttons would be located on either lower or side panel of front of TV and the board is exactly behind those buttons, need to remove back cover of TV to access to touch function board.
Once you find it out in TV then get the part number off of touch function board and search/google it to get price and stock info to place the order to supplier.
Sorry for delayed reply, just logged on website, let me check picture and get back to you in 15 minutes.
Yes, just saw it with current message, so TV is working again? Nice!
If so then it seems some pins of connectors are clogged/ rusty and causing bad contact which affects the TV performance. Please try to unplug and replug a few times all connectors as it will help to refresh the contacts between connector pins or use WD40 contact cleaner spray while TV power cord is unplugged, check following link for details, hopefully it will help to resolve the problem.
Yes, since TV is working with these boards so it would be connection issue between board that stop them after some time. Contact cleaner spray will also help to clean the contacts for better connection but please use it carefully and avoid any liquid left on circuit board or on components before plugging TV back in power outlet.
I can give you ideas based on info given in this conversation and can't see the things in TV so need to try the suggestion to see if it helps? TV symptoms posted earlier point towards two suspected boards and TV turned On while troubleshooting it that made me think it could be bad contact as well, if we use contact cleaning spray and give TV some time to see how it goes that would be helpful.
I would also suggest to clean the touch buttons area on TV front with moist cloth to remove any dirt etc.
No, if refreshing/cleaning the contacts doesn't help then board replacement will be next option as some times processor chip do fail/stop working when chip internal temp increased or any lose soldering joint under the chip caused some problem as there are lots of possibilities.
I trust my input will help you out. Please feel free to respond if you have any additional questions.
Sure, take your time and reply back with the result or rate the answer when satisfied.
Thanks and good luck!
OK, I would replace touch control board as first thing which isn't expensive and worth to try.
Use the part number off of touch control board in TV to search/google it to get price and stock info to order it, this will help to resolve the issue or we would be sure that main board is bad and at that point you can make decision to spend money on this TV repair or invest it on new replacement TV.
Resetting TV to factory setting in service mode can cause more complication because we don't have backup data to get TV back in current status and this will stuck us with new status of TV, we can try it if we have detailed data of service mode otherwise I would stay away form doing that, after doing so in service mode that would be lots of fine adjustments required and we don't have proper tools to do that.
Did you get the touch control board and what was the price?
Yes, sounds reasonable and worth to give it try.
Its correct and happens, manufacturer made the same but improved part with different part number so please go ahead and order that one and reply back with the result.
Sorry to hear that function board swapping didn't fix the problem, yes, next suspected board is main board that can cause the symptoms mentioned in question, please go ahead and replace it to resolve the problem.
I'm out of ideas what could else it be causing the issue so let me opt out to open the question to all others on website to have a look and hopefully some one would soon be with you to assist you further, you wont need to do any thing but just wait for another expert response.
