Sony 55X8505B
So my TV has decided to starting to play up just wondering if this could be the t con card or would people think this is a ribbon connection problem.
I'm guessing if it is a ribbon problem it's not worth fixing,
The TV doesn't really stand me at anything as I was given it -

Le-375 / hv320wxc-100
Iv been given a LE-375 (its a mini pc with lvds output),
And I have a old HV320WXC-100 screen.
I'm trying to connect to mini pc to the screen but haven trouble getting the picture to display, iv got the inverter working using a 12v relay controlled from the pc using a 24v power supply.
Pc boots up fine back light comes on but no video feed.
I found information on the pc and the screen, I'm guessing iv got the pin out wrong somewhere any help would be much appreciated... -
Re: 17mb62-2.5
Well the inverter only needs 24v and I have a 24v smps and the inverter uses a 3.3v or 5v to turn on/offLeave a comment:

17mb62-2.5
So I have a 17mb62-2.5 main board and power supply is dead, I know it's cheap enough to buy a used psu but I got given the TV and was wondering if its possible to to power up the main board with using a bench power supply so I can test the main board and lcd first.
I know I will need 3.3v - 5v - 12v which I can easily produce but is it even possible?
Any help would be much appreciated thanks... -

Re: Plc-xe40 projector help
Yes iv tried the reset button to no avail, I was hoping to find a way of linking out something inside on the MB to bring the projector on, as iv said there are places for push button switches inside, looking over the service manual these buttons should work when linked out, as the manual has pcb lay out for the projectorLeave a comment:

Plc-xe40 projector help
HI all so iv been given two Plc-xe40 projectors and I can't get one of them to fire up..
Iv looked over the service manual and from what I have read I'm a little bit confused, as it shows that the warning LED will come on if the projector senses a problem but this is off.
Iv looked over a few problem places like lamp don't look blown , thermal cutout continuity across contacts, cover switch continuity across contacts when closed so all look good.
One of my other problems is that iv have NO REMOTE for either of them, so iv used an app called Zaza universal... -

Wanting to learn
So I'm going to be trying to open an electronic repair service in my area working from home, I used to work for an electrical company for over 6 years so I have some experience, but after the loss of my daughter my life views changed and I liked the idea of working from home so I could be with my family, I'm hoping to be doing TVs more than anything, iv fixed a few TVs so far (and a few PCs) like replacing bad caps and changing a few boards but I feel like I'm only scratching the surface of what I could know, so I was hoping some people could point me in the right direction of things I could read...
