SOURCE: 3 year old Samsung 40 inch LCD TV will not turn on

The problem is 4 capacitors on the power supply board. Just had mine done under warranty. They (Sears) replaced the whole power board but you can get larger capacitors and just replace those for alot cheaper if not under warranty.

SOURCE: hdtv lcd 40 in. broken screen face

There is no glass or plastic screen infront of the LCD panel.
If the screen is damaged you will need to replaced the entire LCD panel.

SOURCE: Samsung LE40R73BD DTV freezing, wont chnage channel

i've just some digging around and found that you can access a service menu and perform a reset which sorted the issue for me.

Access the service menu by pressing, in order, whilst the tv is in stand-by mode:

info
menu
mute
power

when the tv comes back on you will have a service menu; select option 12 (reset) the tv will then switch off.

this will reset your TV back to factory defaults.

turn tv back on and you should be prompted to go through the plug and play setup again - go through everything and then all should start working OK (it did for me)

SOURCE: My SOny Bravia 40 inch LCD TV has a vertical line

Hi,

It could be 1 of 4 things:
1. One of the ribbon cables has worked itself loose (Simple Fix)
2. One of the assembly boards maybe faulty
3. The driver board which feeds the panel maybe faulty
4. The panel is faulty

The driver board in the UK costs approx £70 and approx £35-70 to fit it if this is the fault.

All other parts are between £80-160 and approx £35-70 to fit it if this is the fault.

The panel will cost approx 50-75% of what the TV was worth when you bought it - "Repair versus Replacement"

Thanks

How do i give my tv an hdmi channel? Do i have to buy a hdmi cable? and if I do which cable? I want to use an xbox one but It won't show due to me not having an Hdmi channel so I was wondering howican


HDMI is a data protocol and includes the associated ports and cables it is not a channel. If Your TV Does not have an HDMI port you can use a converter to change it To a connection your TV Does support. Be aware a cable with the appropriate ends is not the same as a converter...a converter changes the language to something the tv can understand.

Connection for y pb pr cables


The color-coding used for the RCA connectors is nearly universal:
  • composite video - yellow
  • audio - red (right channel) and white (left channel)
  • component video - green (Y), blue (Pb) and red (Pr)
Also, these jacks are normally labeled in print as well, although it's sometimes hard to read the text on some equipment.

Match the connectors on your converter box to the corresponding connectors on the TV. If your converter box was one purchased with the $40 US Government coupon, it may not have the component video outputs. The only coupon-eligible boxes are the most basic models, and they sometimes have only RF (channel 3 or 4) and composite video outputs available.
