    As I probe the board, when I hit the cold connection will the set shut off or will it just effect the picture quality? When I find the cold connection, can this be re-soldered or do I replace circut board? Thanks Dave

Setup unit so you can monitor pict from behind. carefully probe pc boards  with insolated tool. start in large area. try to narrow down to small area. down to componet area. can be very time consumeing. odds are will be cold solder connection.

Connect roku tv to Sony Trinitron


The roku has a cable that you can connect to those 3 plugs. Take the HDMI cable back and give the salesman a piece of your mind. Once your roku is set up you can watch much more than NetFlix.

What kind of cord do I need to connect my laptop so Netflix Movies can play on our T.V.?


Hi Candice,

First, without the model of your TV *and* laptop, no one will be able to give more than general information. It is much better to provide too much info than not enough - to get questions answered quickly here. With that said..

The short answer is that you need a cable that will connect to your note book (most likely either Video [yellow], S-Video, VGA, DVI, Display Port or HDMI) and the TV (most likely RF, Video, S-Video, PC / VGA, HDMI or RGB) Only the HDMI cable will provide sound with video. The others will require either an audio connection from the laptop (probably via a 3.5mm stereo headphone output jack) to the TV (most likely standard "RCA" jacks [red & white] - or settling for the laptop speakers or external amplified speakers plugged into the headphone jack.

If you are unable to locate a cable that has the connector supported by the laptop with a connector offered on the TV, it is likely because it is not possible to connect the two (HDMI to video, etc.) with only a cable. Additional hardware (probably expensive if available) will be needed to up or down convert & split audio to make it compatible.

Take a photo of the jacks offered by your laptop and those on your TV to a respected TV / Audio store / department for additional assistance. Some Radio Shack store employees are very good - and some are just plain horrible. Save your receipts in case it doesn't work to your liking.

Keep in mind that a $50 Roku box will stream Netflix (and a whole lot more) to most TV's "right out of the box" - or by buying $10 HDMI cable online to connect an HDTV. Don't spend 20, 30 or more dollars on an HDMI cable unless you want to pay too much!

I hope this helps and good luck!

Good luck!

Hi I accidentaly actiivate the child control on my tv and turned it off, I don't have the original remote any longer and I can not turn on my tv. Please help Mike


Concerning the problem...it is extremely likely that you have a corrupt EEPROM. A very common problem with this TV.The correct EEPROM (IC location IC 002) is dependent on which microprocessor (IC location IC001) and which stereo decoder (IC location IC 1001) are present on the board being repaired. Take this info to a TV tech and they will find the correct EEPROM to replace. Your TV will come back to life. If not, give me the numbers of ICs IC001 and IC1001. I will forward the correct EEPROM part #. Then the tech will repair your TV. Thanks for asking and show all hands of support!

Samsung le40a lcd - picture quality


Hi - I have some suggestions. The following factors effect picture quality:
1. Source (because LCD TVs have much higher picture quality than traditional CRT "Tube" TVs, the worse your source material, the worse it looks on a LCD TV).
DVD and Sky/Digital TV should look excellent on this TV when connected with a good quality Scart lead (nothing too expensive, but a Oxygen Free Copper Gold lead may help) directly into one of the TV's Scart inputs (avoid using "switching" boxes for multiple equipment).
Also, bear in mind that this is a HUGE screen (40 inches I think) and will REALLY show up bad source material.
The best advice I can give is, if you have HD-ready equipment use HDMI connections for everything (ideally with an HD-uplscaling DVD player which will "improve" the quality of standard DVDs on the TV - I recommend models by Philips) and check that you are in "Movie" or "Cinema" mode on the TV.
Make sure that all of your equipment, like your Sky digibox, is set to 16:9 mode (not 4:3) aswell to preserve the true widescreen aspect ratio.
Hope that helps!

LG 42PX4DV- black and white through external imputs only


Hello freudianslip,

Since you said that you moved the TV set and then this problem occurred, this leads me to believe that this is a case of mechanical failure (cold solder connections). I say this because so rarely does moving a TV cause a failure in the electronics of the TV.
Now to fix this problem one might suggest that you take a soldering iron and some solder and start locating the possible cold solder connections and touch them up. I will not suggest that, because most sets now have SMCs (surface mounted components) which require specialized equipment to remove or to refinish soldering work, even with the right equipment there is a chance of doing real damage to the TV set.
I say, since you know the approximate area of the problem (DVD inputs RCA Ports), you should relay this to a qualified TV repair person and then have them troubleshoot and repair this problem. I know this was not what you wanted to hear since this is a fix it yourself site, however as a owner of a TV repair shop I have had many people bring their sets in after effecting repairs on complicated electronics because someone gave good advise, but the skill level of the TV owner was not up to the level of the person giving the advise.

One the off chance that this is an electronics problem my guess would be the video processor section, in which case taking it to a TV repair shop is a wise decision also for the same reasons mentioned above.

I hope this helps
Thank you,
Shuttle83
