Appliance Repair Questions? Ask a Technician for Answers ASAP
Hi Mr. Cook
Welcome to Just answer
How old is it ?
also can you please count number of Red flashes and tell me how many times does the RED LED blink ?
I bought the set in 2005
The red flashes once then after about a second it flashes 3 times and this sequence recurs
When I try to affect the set by pressing buttons on the remote the red light flashes six times and repeats after a timelag of about a second
can you unplug it and then plug it back after 3 minutes
simultaneously press and hold the Standby button for 10 seconds
then count number of RED flashes and let me know
I have already tired that several times, the fault started last night and when I couldn't get it on I switched it off and it was left off until around 1pm today. The manual did not have any fault finding section suitable so I tried the internet but I have tried switching the set of for varying time periods already.
Not tired I meant Tried
Those flashing lights indicate power supply or main board problem...as it flashes 3 times as well so it can be either due to either sustain or scan driver board that can cause this problem
if you have electronic experience then you will have to take the back off the unit to check the power supply and main board
if you want to DIY then let me know and I will help you with it
however, if not then the repair will cost around £180 to £220 depending on which board is causing this problem
I am a qualified sparks but not a TV technician. I have no problem with trying a repair but it would be better for me to try tomorrow as I have to go out shortly
If I take the back off this evening what should I look for?
First check the board where the main cables connect to
Are you expecting for me to find a broken connection?
Yes or a loose solder joint or may be defective capacitors (most common cause for blinking red lights)
The flashing lights are not random but have two definite sequences, would faulty capacitors cause that or random flashing?
Yes most likely the main board
If I try to find the problem tonight will I still be able to contact you to discuss what I find or will that constitute another repair and additional charges?

Hello again, I tried to rate the service but I get a message saying that the engineer has not finished so I am unable to click on any of the faces
OK, I will exit the session so that you can rate...may be there is some issue here :) Thanks
No luck Kevin still not able to rate do I have to click save and exit first?
I have removed the back off the set and have checked the connections to the boards and they all seem to be clean, good connections.
I can't see any obvious damage to any capacitors, are there any signs that I should be looking for?
The set is now working again, Whilst I was waiting for your reply I tried the standard sparks repair by tapping the items on the board with the handle of a small screw driver then I tried the set again and it worked.
So it seems the components are in good order but there is either a loose connection or a dry joint so I will use the set until it fails again and when it does fail I will remove the board and check all solder connecions.
Thanks very much for all of your help
