Question about Thomson Televison & Video

1 Answer

Dear sir, i am having a Thomson 21MV8DR TV reciever. A few days ago while switching it on, i discovered that there was no audio in it and its remote control (RCT100A) was not functioning. Assuming that the batteries in the remote might have got discharged, i opted to operate the set through its panel keys and found that all other keys except for volume were working properly. Amidst this, a red lettered indication (that reads as) PI gets displayed on the bottom left corner of every program. Now the set is in a dumb state. Though the volume parameter gets displayed when the volume keys on the panel are pressed, the volume pointer has got stuck to the minimal volume count and is not shifting towards the maximising end. I even tried other remote control (RCT100A) as well as RCT100B and RCT100C, but did'nt gain any success. Could you please tell me what kind of trouble is it? Is it an internal audio circuit fault OR some sort of service menu problem. In case it is a service menu problem, how to eradicate it as no remote control is effecting it to any extent. EXPECTING A WORTH SUGGESTION FROM YOU Thanking you YUVRAJ SINGH

If your remote transmitter is multifunction, such sa TV; DVD; and VCR operative; You may be in the wrong mode. Press the TV function first and then try to change the volume. If you still have problems, the remote may be defective.

SOURCE: Remote volume control for Sharp Aquos 42inch LCD not working

User 'rapolley' is absolutely right. One can cycle through the functions to access different options, ie. 'TV', 'Audio', 'DVD', etc. I stumbled upon this solution when I thought my 'Menu' button wasn't working. All I had to do is cycle through the 'Functions' and choose 'Menu' once I get to 'TV'. Thanks!

Thanks Jaime867

Best send repair manual.

I have pics to show / identify problem but I cannot attach to my reply. Parts defective are: 4532M x 2 (UC2 & 3), diode next to diode RC22 & cap C35 and IC6 (cannot see part number). Board number is YPNL-M007B r1.0, also recognized L.G. Phillips part number: LC230W01-A2

My hands are not as steady as years ago to do surface mount solerering but my wife can as she has done this before being electronic equipment assembler.

As stated before I need to find source of what I suspect is short that had blown these components.

I bet a replacement board is more expencive than a new LCD TV!, but I want to resolve this prob and maybe help others...LG too.

Thanks Heaps Jaime867!

How do I switch from coax to hdmi on my Sony receiver?


on the sony site it says the hdmi into the reciever is for the video, relayed by another hdmi to the tv, the audio will still be the coax
I personally would use the hdmi from dvd directly to the tv, and the coax from dvd directly to the reciever and call it a day

Hello
There is an authorised sevice center for Thomsun in karnataka. You just sech for it on google by entering 'Thomsun auththorised service center in karnataka' in the box. You will get a map showing the location of that service center, which I gets here in Trivandrum, Kerala.

There is no need to insist on to an authorised service center, to get your TV repaired. Just consult with local electronic mechanic, in this case, They can do the needy very easly.
Ok.

Tv shuts off sporadically, and now won't recieve any video signal


Check the solder on the vertical output IC this is a common problem and can cause loss of video while sound remains and often will shut the set down with a vertical deflection error
