Dlp tv wont start up/ switches off

My two year old LG Electronics RE-44SZ20RD dlp tv ,when turning on sometimes (getting more common) when I try to turn it on out goes the red standby light and then has to be either unplugged and plugged back in or turn it off/on at the switch on the front of the tv THEN it will start up and work fine all day with a perfect pic. This has happened twice in a row for my wife! Any ideas?

Re: dlp tv wont start up/ switches off



This model of LG set does suffer badly with dry joints (these are soldered joints that have oxidised or cracked)

Its not A job that I would recomend you tackle you may need specialised soldering gear when working on smd type ICS.

Try & find repair shop that does free estimates.

If A repair shop states they will repair in the home offer to take it in to them as this is very difficult to repair in the home & you will end up paying more for them to come out then take it away.

I have a mitsubishi tv model wd 60638 I changed the lamp. Tv works fine for about 20 minutes then I start to smell like something is burning then picture starts to flicker, what could could cause this

You have a bad connector in the lamp. Stop running the TV immediately and contact the company you purchased the lamp from. this is common in older DLP tvs but not in one 5 years old unless you have a lot of hours on it. the connector can crack and arc inside the plug and then melt and smell terrible. It usually very repairable if you can get a ballast for it. the plug is part of the ballast.

Green Lines on Samsung DLP

Either bad capcitors, or (if you're lucky) the color wheel needs lubed up. Probably bad caps.

Samsung DLP TV repair or replace that is the question!

Color wheel sounds like it needs replacement. The set will often shut down when the color wheel gets bad and wont power up.

Samsung rear projection tries three time then goes

There are several things in this set that will cause this. I have ran into this problem 40-50 times on that specific unit. Most common problem is the lamp. Next most common problem is the DMD board which is a very expensive repair. Next most common cause is the ballast which powers the lamp. Next is the color wheel but usually that gets noisey before it fails. These DLP televisions aren't easy to diagnose but they're easy to work on. Now here's the thing, all four of these problems can be solved by replacing the light engine. If you are willing to put some money into it, the engine assembly is real easy to change. Just google the exact and complete model number and search prices of the light engine. I'm pretty sure the part number is BP96-00305J. Sometimes you can actually ship the engine from your tv in to be rebuilt. This can save you money. Any repair on this tv will probably cost 200-500 but they get a great picture. I have a samsung DLP in my livingroom. Good luck, Russmann.

My Samsung 50" DLP HDTV keeps humming when the DLP lamp comes on.

Hi, you have one of two problems, either the color wheel is going or one of the cooling fans are going, the color wheels are a very common problem in samsung dlp`s, sorry I can`t nail it to a specific part but I`d bet it`s the color wheel as they are notorious for failing in samsungs, video-tek

Picture getting darker over the years

It could be your Light Engine. However, I would first check a few things:

1. Make sure your Low Power/Lamp settings are adjusted so that they meet your brightness needs.

2. Make sure you used a Mitsubishi original lamp, as generics get chewed through fast and hard.

3. Try another lamp; sometimes you can get a bad one in the bunch.

All those things don't work, consider a Light Engine ($400 + for parts; $300+ for labor)
