There are still dangerous voltages kicking around the switch mode supplies. Always be careful .

Remember, blown/bulging capacitors might be a sign of another component that could be failing too. You might replace them all and they just blow again.
Change the capacitors for a cheap/quick fix, but it's not guaranteed to solve your problems.
Does the board have any identifying marks on it that could help your source a new one should it come to it?
I've had good results after changing the capacitors, but I've also needed to swap the boards on a couple of occasions.
eBay is full of stripped parts from TV's

http://www.ebay.co.uk/sch/i.html?_fr...&_nkw=VO+Board
But you're best searching for the Product number.
Nothing on ebay, found this http://tvpartsfixit.co.uk/?Set=L32HP...earch=LCA90463 £34.99 including delivery.
Remember i don't know if its faulty.
Heres a side pic. as requested.
I would say, seeing as the TV switches on, that board is not at fault.
I went back and investigated (I should have done that first!).has sound but no picture. I had this all apart yesterday and backlight is working. Should i be looking at the main power board assy?
Reading what you wrote, I would be checking the Video Output Board - the one the LCD itself connects too.
Post a new thread and I'll try to help you further there.
Also, for the record "JVC LT-37DSB6" doesn't exist.
JVC 37DS6?

There wasn't any but there's no means of checking whether it's on a channel (or input). The power button light is on for standby and when I use the remote nothing happens other than the light responds to it. There is also no initial delay for the screen to come on, no clicking, nothing.
The tv is off the wall now but if necessary I can put it on the stand and plug it back in to try things?

I already repaired my Samsung 206BW monitor a few months ago. Soldered in some new capacitors and job done.
Percy, Just want another opinion before I open it up.
My mum's tv (Goodman's 32" GTVL32W17HDF) She was watching it last night and the screen started to go dark. She turned it off and back on, the no signal screen came on first (Blue screen) Then went narrow and then black.
You can hear the tv channel sound but no picture.
Had this before on my monitor and changed the caps, does this sound like a cap issue or panel?

My sister left her Tele Box on all day while at University and came back to this -
I've pulled it open and had a look at the boards, they all seem perfect.
I removed the 'Picture Board' labelled RUNTKA561WJ. It looks ok with no obvious signs of damage. I though it may have got hot and the solder move, so reflowed it horizontally, but still the same thing.
Checked eBay and one replacement for it is available, http://www.ebay.co.uk/itm/180961825091, but wanted to make sure it couldn't be anything else before buying it.
IE Capacitors - Looking at them all there is no obvious signs of bulge, leaks etc.
Could it be the LCD has completely died? Where would you check first faced with a TV like this?
Hi guys, two questions, sorry if they seem very basic.
1. What type of capacitors, know I need electrolytic, but are the ones in an lcd tv lead or smd(what's the difference) and are they radial or axial.
2. Is there any reliable way to check them on the board, have 18 32in lg's to sort at the moment, would save a lot of work.(even though I'll change all as soon as I can, time permitting).
Oh, does anyone know of a supplier for kits (capacitors or possibly whole boards) for LG tvs.
try and use a bigger soldering iron when dealing with Caps on a TV. Smaller irons dont pack enough heat to remove the stubborn old ones.
