I have a 42" LG LCD television. It was purchased in 2011, so well out of warranty, but is suffering a problem that seems to be very common on LG TVs made that year.  The TV was telling me the Sky box had no signal, so I spent hours pratting about trying to get if fixed, but in the end it seems all four of the TVs HDMI inputs have stopped working. Fortunately the Sky box and TV both have a SCART socket so I can still use the Sky box. Now, reading on the interweb I find a recommended solution that many people have tried with success. Remove the circuit board from the TV and bake in the oven for 10 - 12 mins at 200C. Now, do I try it or not ?  zedic.com/lg-42dl550-fix-repair/* |

I guess why not, what you got to lose as the TV is already effectively broken and if it works it'll save you a pretty penny.
My Dads plasma recently broke and he chose to have it repaired but it cost around £350... Personally I wouldn't have bothered as you can get TVs so cheap these days.

Not impressed with LG TVs - bought a smart tv at £600 and the Netflix app doesn't work on it - apparently it's a known problem, and a stand-off between Netflix and LG - yet they still sell them using Netflix as a selling point.

Remove the circuit board from the TV and bake in the oven for 10 - 12 mins at 200C. That's not hot enough to re-flow solder, so perhaps it fixes a problem with a self-repairing capacitor or a crack in the PCB track? It's probably a sledgehammer approach, but if it works you've saved a TV. Otherwise, you're looking at taking it to the tip. |

Can you not simply purchase a new circuit board and replace?

The problem with spare parts is the frequently hugely over-inflated prices. These days it's often better to buy new than to repair even if the part seems small. I encounter this all the time at work, a spare part for a projector, printer or even a laptop (such as the screen) renders the repair not cost effective as it's over half the price of the new or equivalent item.
This week we needed to order a maintenance kit for a printer: it was priced higher than the cost of a complete new one.

When I was maintaining computer equipment that was a standard fix for HP printers whose network cards had failed. As observed it's not hot enough to actually melt the solder, but I have no doubt that it works in most cases. Worth a try anyway if you don't mind the risk of killing it completely. |

That is the quandary. As a TV it works fine, and I can use the Sky box and DVD through the (single) SCART connector , so it's just inconvenient. If I try cooking the board, and it buggers it up good and proper, then it's mucho spondoolics for a new TV. I'll try searching the net and find out if new boards are available. |
