Sorry you are having problems here I am currently reviewing your question be with you in a min
Is there any power-light lit or blinking please on the front of the set?
HelloIn every case where their is no power light lit and you are sure their is power reaching the set you have bypassed any surge limiter you are using and gone right to the wall, also moved the set to another socket, the back of the set will need to come off (set unplugged from the wall)and some checks carried out using a meter (volt\amps\resistance)this is just to verify if the powerboard is bad, are you able to do that yourself?if so please let me know I will provide more details, the most likely suspect as it stands now is the powerboard itself.Please let me know if you can do work or need more info
Sorry it is nothing easier, just to clarify the board is a plug in board no soldering.
Please at this point could you rate the answer positively with the rating bar of stars at the top of the page,(3 to 5 stars) rating me positively enables me to receive payment from the site thank you, ***** ***** question is open for 30 days
OK good, I am assuming you are not hearing any clicks from the set, if that is the case the first thing to check is the sets own internal fuse this will be mounted near where the power-cord enters the power-board, you need to set the meter to ohms (or buzzer continuity) and with the set disconnected from the mains measure on ohms across the fuse what reading do you get on the meter please?
If you do not understand please send me a photo first of the complete inside of the set then one of the power-board I will send it back marked
Please also send me the model number of the set fond on the back of the set
You can send a photo there will be a paperclip or similar your end to send it directly here
Oh yes of course the back of the set will need to come off
There is no rush and no time limit take your tie, there may however be gaps in replies as I deal with others
OK fuse is good set the meter to AC black lead to metal chassis red led to the fuse do you have 220vac on the fuse either side?plug into mains now
You see the powercord its unpluggable yes?so you see the two bottom slots left and right of the cord itself put red and black in there (lead on its own) and switch on power meter set to ac are you reading 220vac?
You see the bottom left plug on the power-board the one that plugs into the mainboard (one with all AV inputs on) set the meter to dc and go to each pin of the plug looking for a 5v DC let me know if you find that or not
Yes 20vdc is good red probe to each metal contact of the pin black lead to metal chassis of the set
Yes that plug try to touch with the red probe each piece of metal individually you are looking for a 5VDC reading if you do not get it that is fine this will lead to diagnosis
Red lead to each pin black lead to metal chassis so any of the solid metal the boards are attached to
Power-board is bad
Can you please get me the full model number of the set found on the back of the set?
I can only find one for £100 above but have a search yourself I have seen the board for £30, use the part-numbers found on the board itself to search, it can be time consuming but yu may find the board a lot cheaper
Please before you go remember to rate me 3 to 5 stars with the rating bar of stars at the top of the page thank you (scroll up) this allows the site to release a payment to me thanks again not the question remains open for 30 days so bookmark this page
Yes its why the board must be obtained more cheaply and yes I understand your thinking
