Question about Televison & Video

1 Answer

Hi there my mum has a 42" Technika Tv Model LCD42-207. When it is switched on there is no blue light or anything on standby hence it wont show a picture or sound. The guy who came to look at it was suprised to see it was getting too hot inside too quick and he thinks it needs a new circuit board. He was unable to obtain a circuit board for this tv do you know whree I could purchase one and if this is the problem? Many thanks

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. 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.

Hi brendafoud, have you had this fixed as mine is the same and has been for months. It happened just after the warranty had ran out(typical). Bought from ebay and the people I got it from are not very helpfull. Have you got yours fixed yet?

There's a good chance you have failing electrolytic capacitors either in the power section or the inverter section or both.
Any caps in these sections that look bulged at the top, or bulged/leaking at the bottom need to be replaced.
If you repeatedly turn it on, eventually it'll probably stay on, but every time you turn it off, the TV will get harder and harder to start up until one day it just won't.
Sometimes you have to do the opposite to start it up and unplug it for 5 mins, then try.

If you aren't tech savvy, this unit needs to go in for repair.

If you are handy with a soldering iron and can identify the power supply and inverter / FM section for the backlights, an inexpensive handful of capacitors will likely fix you right up.
Match the capacitance on the capacitors. Go over voltage if you can, and still have them fit.
IE - it's not a bad idea to replace a 10V cap with a 16V or 25V or even a 50V, but don't replace a 680uF cap with a 500uF or a 1000uF (unless you are positive it's only doing ripple filtering).

Most of the caps that go are 10V 1000uF or 3300uF.

I found some great videos of the procedure (for different brand, but same issue) on youtube.

As you can see, this issue spans plasma TVs, as well as large and small LCD TVs and monitors.
The parts are cheap, and skill required is minimal.

How many times this standby/power light blinks at one time switch ON? Count it carefully. These blinks are fault indication, and known as blinking codes. From the number of blinks occur at one time switch ON; you can get an idea about the faulty circuit stage inside the TV. This will make repair easy.
