Question about Sanyo Televison & Video

1 Answer

I purchased a SANYO TV (Model: CM29FS2) two years back. Recently I experienced a fault from this TV. After warming i.e. 30-45 minutes from switching on, a sound (like the one when we turn on/off any switch in the same switch board) is produce from TV speaker. Then the TV restarts automatically. This is heard even when the sound is set to mute. This will not happen if we disconnect video (i.e. by removing video jack). I called authorized service engineers for repairing this fault. They attended and re-soldered all dry soldering. But the fault still continues.

The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Seems like the auto upgrade in standby mode feature was the culprit.

Switching this off from D MENU>SET-UP>SYSTEM>SOFTWARE UPGRADE did the trick.

BTW my firmware version is T-TMDEUC-1003

SOURCE: Which Replacement Power Board for LNT4665F Samsung LCD TV?

Howdy,
It would be a lot cheaper if you just replace the two caps that have gone bad. Just get a cheap solder pencil from the store and about an inch of solder and you are in business.
The Power Supply Board is the center Board (towards left) after you remove the back off the TV. Remove Board from TV with the 6-7 screws. Replace capacitors CM852 & CM853; 2200ufd 25volts.

Thaks for using FIXYA, BIG IRISH.

Does my Sanyo tv have a VGA port? If so, where would it be located?


The ports should be located on the left side back of the set.
Look for the video input RGB.

Tv repair


I have had 3 flat-screens so far, a Polaroid, Panasonic and now a Sanyo. In my experience when this happens, you would remove the back, clean and dust it carefully. If you have never done this before, it is very wise to leave it to the more experienced as the circuit board contains some sensitive parts. The circuit board needs to be looked over for any damage or burn marks. This could reveal the problem. Also, check for blown diodes. They are roughly shaped like a pencil eraser and should be flat on the top. If they are rounded or appear black, they are bad and need to be replaced. Again, if you've never done this, highly recommend leaving it to the more experienced. Hope this helps.
