LG 43UK6470 (and similar) no image/display repair - Backlights ok

We are seeing a number of LG tvs (usually 43" and 55") that are coming into the workshop with no display/no image however the backlights and other functions seem to be working ok. This can be down to a fault on the lcd panel (aka the screen) and instead of replacing the whole lcd panel which is usually uneconomical - we have a good chance of repairing the existing one and getting a perfect picture again. If your LG model is not ...

LG 42LS575T Led tv intermittent no picture/backlight repair (sound ok)

Posted by Peter Hancock on Monday, November 2, 2015, In : Repair

If your tv is suffering from loosing its picture, while the sound stays on ok, then it is worth us (or any other professional tv engineer) having a look as we could save you from having to pay out for a brand new tv. Initially the picture...

Backlight/No Picture Repair on LG Tv models 32LN5400ZALG, 47LN5400ZALG and 50LN575VZE

We can now source the screen components required to repair LG tv models that suffer from no picture/no backlights issues (but the sound comes on ok).

LG (and other manufacturers) have long denied tv engineers the parts required for this economical repair which meant a lot of tvs got unnecessarily thrown out at the dump by people. It is very encouraging to see LG and Samsung now starting to supply screen components and hopefully others will follow suit.

Please note that LG do not yet supply scre...

Toshiba 40L1333 LED TV sound no picture/backlight

Posted by Peter Hancock on Wednesday, February 11, 2015, In : Repair 
We are starting to see LED tvs in the repair shop now, it seems to be that the new LED technology is having some teething issues and are failing earlier than expected.

We are still at the early stages of repair methods for these, however we have had some good success getting the picture back.

If you have a Toshiba LED tv with sound, but either no picture or a very dark picture then it we should be able to repair it.

Affected known models:
Toshiba 32L1333
Toshiba 32L1333D
Toshiba 40L1333
Toshiba 40L1...
