Question about Televison & Video

Open Question

Bush Model: BLED24FHDL8 Seriel: R3AN201129A01836 24inch LED TV will turn on fine but after 5 or so mins the screen will pixelate and change colour. The Tv will then turn off and turn on when it chooses. I can't turn it on manually unless I turn it off at the switch and turn it on with the remote. Any ideas on what's wrong? Also it doesn't turn itself off on the 'No Signal' screen.

SOURCE: TV changes channels itself

Have you checked to see if any of the front panel buttons are depressed and stuck??? this is a big problem these days?? I have also found the infared remote sensor to be bad on some sets that do crazy things all by them selfs.. A funny storry once i had was a customer called me after her mother called some goast finders as her maggy projection set would go on all by itself andf the channels would change and the volume would go up and down all by its self. funny thing I had a set just like thast in the shop at the time with the same problem and I scoped out the output pulse from the infared reciver on the set and that was putting out noise on the data line and caused the set to eratacly do all sorts of weird stuff. get the point?? its a stck button or the remote sensor is bad.

A qualified tech will need to practice visual acuity technique! Look at power supply circuit for signs of stress,dis-coloration and/or bad connects.Check for bad 47mf/25v cap in area of stress.Replace BC-327-25 xistor w/BC-328 and replace BC-337-25 w/BC-338,if present in your set's chassis style.

Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Bush TV, model number RF6685VPL/A - Colours are wrong!


It seems that it is a degaussing problem. TV sets have a degaussing coil that when the TV is turned on , it automatically demagnetizes the screen. Never place any speakers or anything magnetic near or on top of your set. if you see swirls of color and like you say, wierd colors, it is that the screen is magnetized. Turn it on and off with the switch. Not the remote control. The degaussing coil only works by manually turn the switch on and off.
