PANASONIC tx-cx400b Picture loss....

[andrews7523]

This tv works fine but after a few minutes it loses the picture. Backlights stay on, I'm thinking Tcon replacement but would like other peoples thoughts. I have the option of buying a Tcon or main board o ebay and would prefer to get the correct part first time round

Much more likely to be the LED String Inside the panel....

I'm guessing it goes completely black. If so, use a strong torch and look at the panel at an angle--if you see the picture--The LED's are not working.

You fail to give screen size for your set? If the back light stays on as you say, then its not going to be the back light LEDs. you would need to see if all power voltages are still there when you lose the picture

These sets are made by Vestal for Tesco and Argos and are bottom end, have seen lots with faulty main boards,Andy at Ohm supplies sent out a news letter with repair details a short time ago for the 17MB xx boards. so look on his site, or drop him an email hope this help

The public know the name Panasonic and think top end as they were back in the day, But like all the rest, they have sold there name out to Vestal.The only good thing is the delivery drivers Tesco/ Asda/ Argos seem to like damaging the things so loads of parts out there when they do go wrong

Yep Vestel crap with VES400 Lcd, probably lose connection in the Led strings. If the Lcd turns off but BL stays on I would suspect mainboard had a Hitachi which come on shown the logo, then no image on the with BL still on, was Mb issue.
