Thompson 32" Widescreen TV Problem Error Code 27

14-04-2008, 7:23 PM

Hi all - trawled the net and found this site and am wondering if you can help.

I am currently having issues with my Thompson TV.
At startup it occasionally tries to start 3 times then gives error code 27 deflection detects >3 times prot. - it also occasionally dies during use but this is rare.

Usually after a few full power downs and restarts it starts up. The picture is fine and I dont believe that there is anything wrong with the deflector. Anyone had any experience or knowledge as to what this may be and any possible solutions (I can work around a circuit board but obviously not having any repair manuals I'm stuffed

Any help appreciated.

TY

Keith.

You need to report back with the model no of your Thomson

I'm pretty sure that model uses the ICC17 chassis...can you confirm?...it will be printed on the rear label.
If it is an ICC17 the most common fault giving error code 2/7 is the line output transformer is short-circuit...the replacement comes with a modification kit consisting of a few coils, capacitors and resistors that must be replaced at the same time.

Many thanks for your response.

I will check the chassis no tonight.

If it is the Output Transformer I may put it in a repair shop. Being a telecoms engineer I am used to working on circuits that are a tad more passive.

Thanks again!

Many Thanks JayCee have checked and it is the ICC17

One last question - Roughly how much would the replacement transformer cost? Just so I know that the repair man is giving me an honest quote :-)

Regards,

Keith.

If your set eventually starts up after a few tries and runs ok i would suspect something other than a faulty loptx. A faulty loptx tends to keep the set from starting up.Either way i agree you require the services of a engineer.But it might be less expensive!

Agreed.
I hadn't read the original post fully and dived in

Lopts don't go intermittent...could just be a dry joint on the frame IC or a duff capacitor in the power supply...so shouldn't cost too much.
