    Hey Andy,

    I was wondering if you could offer any suggestions as to how I tackle the problem of having just a white line across the middle of the screen with no picture or sound, and obviously the set is a 32in lcd, modekl no:30112, now having looked at the comments relative to this product, it appears to be very problematic, but I am optimistic i'll get there with the right help. Many thanks Michael.

LG 32LH200 stuck on standby mode. pls assist


Im afraid the set is probably in an over current protection mode wherebye it shuts
down to protect itself as one area of the tv is drawing excess current, if the tv led light attempts to change colour at start up as normal or flashes etc this would verify my suspicion

led flashes etc can have a code which would guide a techie to problem, im afraid you

will need an engineer visit,sorry George

Hi I have an LG LCD tv and this morning it just went dead, as if there is no power getting to it at all. The electric supply is ok Regards BMcD


If it is completely dead (no standby light, flashing LED blinks), the power supply failed. Replace the Power Supply board to fix.

Standby LED flashes red 4 times with pause then 4 times


You either have a bad fan or one of the rotation sensors mounted on one of the fans has failed. Take the back off the set and see it the main fan slightly right of center is rotating. If it is, there are two more fans, one mounted right above the lamp and another on the optical block itself. You will have to pull the optical block to check those.

Help with kogi F9AH screen


Intermittently displays bright red/green/blue raster then shuts down with led flashing 2, 4 or 5 times
Amazingly this was due to the CRT being faulty !

Blank raster
Replace defective TDA6111Q for Red, Blue and green

Red or Green or Blue screen
Check and replace on crt module : D702, D703, D704 (all 1N4148) replace with type 1N4948T

Dead, led flashing red/green at first, then going to red standby
Replace C604 (1000uF, 16v) elec. cap. It is in the decoupling circuit for the 5 volt supply
