Re: Sharp Aquos Flashing Standby Light!
Any ideas where i can buy the sockets in the UK please?
And is it possible to test these by removing them and powering up to see how many are faulty?

Re: Sharp Aquos Flashing Standby Light!
i've stripped off the inverter board and there are three points where it looks like its burnt on the sockets ( No. 2 , 3 , 7) can these be repaired?
ThanksLast edited by studfish; 10-20-2014, 05:24 AM.Leave a comment:

Re: LG 50PC55 Plasma Vertical Bars!
just as an update......
I changed the mainboard and now the standby light turns from red to green so there must have been some kind of problem with the original.... all other problems remain howeverLeave a comment:

Re: LG 50PC55 Plasma Vertical Bars!
Hi Tom thanks but even when i have devices connected and change the input using the controls on the tv i still get no signal.......... main board?
Also if i press the menu button the tv turns off .
The Red standby light does not change either it just goes from red to offLast edited by studfish; 12-08-2013, 06:32 AM.Leave a comment:

Hi I have tested the new buffers and the top buffer is showing as having a blown ic.
Would this cause the no signal problem though ?Leave a comment:

Re: LG 50PC55 Plasma Vertical Bars!
I've just been looking at an online manual and it states the light should turn green?
I removed the z-sus and re-soldered the joints checked fuses etc. the tv now does not turn itself off however no matter what i try to connect to it.....hdmi rgb scart antenna it doesn't seem to be able to get a signal from any of them?Leave a comment:

Re: LG 50PC55 Plasma Vertical Bars!
There is no sound coming from the tv either even with devices connected to it..
I have had both the ysus and xsus disconnected and still no green light
I have no remote for the tv either and if i use the buttons along the bottom the tv turns offLeave a comment:

Re: LG 50PC55 Plasma Vertical Bars!
Hi thanks for the replies..... sorry for the noob questions but im new to this.
I assume the "No Signal" box means I have no Arial dvd etc connected?
Those bars still appear when i have Arial dvd etc connected.
Any ideas why the green light wont come on?Leave a comment:
