Thomson TV model 15LCDM30B locked on standby

I have a 2004 Thompson LCD flat screen TV which I have fitted in a stretched limousine. Whilst mucking about with the menu I clicked on lock and now I cannot seem to get the TV to come back on (no green light) The red light comes on for a few seconds then goes off and then back on again etc. Please can anyone tell me how to unlock the TV or where I can download or buy a user guide for this model TV?

    Replacing the faulty remote controller did the trick. When in standby mode it appears that the only way of turning the TV on is by the use of the remote control. No sequence of button pushes/holds using buttons on the actual TV work.

Thomson 27lcdb03b picture upside down

I would suspect main board more than one you replaced--not likely to get help as Thompson is not known for that--possible firmware upgrade seems likely.

On every set I have seen with upside down/inverted or reversed screen etc it has been either a firmware issue or a main board.

I have a Thomson 27LB130S5U TV - have connected to my laptop with a VGA connector (both ends) but no picture coming through to the TV. Same laptop with a different TV no problem. Am I missing something?

It is possible that the VGA interface in the Thompson TV could be deffective. You will need to check for any break in the connectors, bend pins or within the printed circuit board. Since the TV is working fine there is a possibility only to find such a break or a failure of the VGA interface IC. Take help to make a test before you can replace. Hope the selection on the thompson was selected to VGA and still you did not receive the signal Please check this out. Good day

I have a LCD TV THOMSON 32lb040s5, the problem is that the TV start and turn off again and again when I start it

you probably have a fault on the stand by power board.
this normally requires soldering and maybe some componet changes. This is not a job for the unskilled. best carried out by a service engineer(shock hazard)
there is a service kit for this available from 012453925
