Anyone know a good company to repair a tv. My lg lcd just stopped working. Won't come on, as if there is no power. Fuse is good, cable is good as i tested it on my monitor. Took the back off to check popped capacitors but they look ok still, but i don't have an esr tester anyway for a thorough test. Don't know what else. Warranty went about a year ago!

did you check inside for a small fuse, about half the size of a fuse you get in a plug? Usually near the transformer. Had one of those go on my old flatscreen. Couple of quid from Maplins for a pack of ten.

You may want to ask a mod politely to move this to the Tech Shed

I was looking for the fuse, but couldn't see one anywhere.

I should have posted this in the tech shed yes, daaa!

Can anyone see the fuse on here

Have you emailed the LG tech department as they might know what is wrong.

Any good?

Yeah already tried those, they all look new as does the whole of the inside really. Going to take it to a repair specialist eventually. I'll take one more look with fresh eyes later.

Maybe a bit far but try theses peeps.

They are a repair comp for the utilities so cover many makes.

Tell them carl the sparkie gave you the number...you should get a good price!

Ok thanks

I'm guessing your TV is a 32LX2R by LG - that's a Yuyang YP2632T power supply. They're awful things; there is a repair it available for it that replaces all 14 electrolytic capacitors in the output stages of the PSU (top left corner in that picture).

Good used ones are virtually extinct unfortunately.

I am going to replace them all either with a kit or buy them individually. How did you know the exact model?

I have another one bigger and better so whenever i get this repaired isn't a big deal. It will just go in the bedroom and consume more electric!

I work here: - FlatTVParts - it's fair to say I've dismantled over 10,000 TVs for parts. There's not much I haven't had through my hands

Can you help. I have bought some capacitors for the board. However, the 4 1000uf 35v have been replace with 63v, which from what i have read is fine. But two of the four are only 85°c instead of 105°c. Is this going to make much difference or should i go back to maplin and change it?

Thanks in advance

Makes not a jot. My old LE40R73BD with the infamous 4 cap Samsung PSU of doom was repaired with 85 degree caps from China nearly four years ago when I started working for FTVP and has clocked up over 17,000 hours since without failure (seventeen thousand hours...)

Sorry to thread hijack but whilst their is a TV tech on hand i thought i would just ask if you know how difficult it is to fix a backlight problem on my LCD. its not LED backlit like the newer TV's i think its cold cathode ray or something but anyway i have large areas of white clouding when the contrast brighness is turned up you can see it when its on normal but turning brightness up makes effect more prominent. Im loathed to change the TV as its stunning other than that and i love it. Its a Sony KDL-46X2000. I have fixed TV's in the past but these were old Tube TV's with shadowmasks and deguasing rods etc. Never even had the back off an LCD.

Can you get a picture of the evidence? I've dismantled hundreds of these and can't say that I've ever come across this before. The TV is getting on a bit now, and it may be one or more of the CCFL tubes in the light box is starting to get tired; this usually manifests itself as drak patches around the edge though.

That surprises me as its a well know problem there was a massive thread about it on avforums a few years back. Yes its getting on a bit but its a masterpiece of TV design and i love its clear glass bevel that lights up sony etc and its still 1080p so im loathed to get rid of it even though i have already replaced it with a newer model. Not my picture one off google but mine does the same thing except the clouding is more to the left hand side.

Think this is what happened to a friends Samsung, but they were quoted as much as getting a new TV to get the PSU fixed or a new one.

That looks very much like a tired diffuser sheet behind the LCD panel. Can't say I follow AV forums, but I'd quite happily live with that; these old Wax2c based Sony LCDs are a pig to work on and a screen change is probably a 2-3 hour job for someone familiar with them. I'd rather have an old Sony or Samsung over anything modern, especially edge lit LED ****. Talk about flimsy crap with poor light dissipation.

Sad. I used to collect, repair and deliver back for 85 quid. Or repair the board for 40. What makes me laugh is when people have a go at them themselves, make a mess of it then whinge at the clean up cost. It's the primary reason this trade is on its backside due to have-a-go-heros leaving nothing for us to do the job properly and provide a warranty.

Hiya,

Just thought I would pass on my experience with this.

I have owned a Sony KDL-55x4500 for the last 3 years 4 months. Typically about two months after the warranty expired (one year), it started to show signs something was wrong.

Intermittently, the screen would just fail to come on and there was a flashing on the power led that indicated that it was due to a failed main panel or the main board was faulty, according to the NET. Incidentally this was reported by professional TV repair guys (one of them appointed by SONY to answer questions on an AV forum). In other words, what they were saying was £500 plus to get fixed.

Needless to say I was gutted at the time. I dreaded even giving a fragile 55 inch screen to the nearest Sony center to me (Dundee) as I did not have the box or the substantial packing and padding the TV arrived to me with.

One of the forums did say something that had me thinking though. They mentioned checking the main wiring loom. This led me to relate to computers in general, where in my experience, quite often a failed hard drive or graphics card or memory failure was fixed by simply unpugging or reseating or reconnecting.

So I thought it would do no harm to try this with the TV. And to my astonishment and relief it worked!

So I removed the back panel and simply unplugged or shoogled all connectors I could and reconnected. FIXED....for six months or so

I repeated the procedure and it worked for a further 2-3 months. This time I was sweating.

But then I thought, spray on electrical contact cleaner. Before anyone asks, I did make sure the TV was unplugged and waited for around an hour to ensure the spray had evaporated. So obviously we have to be careful here. I used the Halfords Electrical Contact Cleaner for about £5.

Thankfully the TV has had no issues since for the last two years.

So I can only say that this is worth a try.

Cheers,

Raymond.
