What is the model number?

Hi,

May I know if the chassis number of your TV is ITC008? If not, please let me know what its chassis number.

any one can give me the smps circuit diagram using P5NA80FI mosfet in thomson ctv ?

The cost of ordeering a replacement part from outside India will be worth more than getting yourself a new set.
You have 2 options you either look for someone with a similar unit and a different problem and get their part.
Or simply just invest in a new set.
Hope this solution is helpful?

i think thomson has disame chassis with tcl tv.

Try replacing the eprom. If that somehow became corrupted due to HV surge or otherwise, you would have this symtom. The eprom contains information that basacally tells the HV circuit to turn on.

Zaburi,
It's probably micro or tac switch related but that chassis has to be one of the worst pieces ever built... Good news is you can buy a new one for very little cost and some wholesalers were selling the complete chassis for under $75.00 dollars.

You can get the service manual emailed to you at the following link. The manual is listed under Thomson the ITC222 chassis is a thomson which is RCA It cost 12.99 but they provide free on line tech support to help you with your diagnosis and repair and they also sell parts with free installation instructions.

1)Whenever the word "sometimes" is used,a good visual inspection of PS,horiz,regulation & vert. circuits are needed.Solder any/all bad connects. 2)IHVT aka flyback is the usual culprit. Get part # and ask distributor how popular it is? Any info gathered when doing repairwork can be helpful.!
