SOURCE: ballast replacement

Your set uses the Phillips UPH100W 1.3 100http://servicemanuals.vstore.ca/ 1amp bulb part number 6912V00006A which uses Ballast EUC 6913V0002A and the actual ballast isMB03CA part number 6871VSMB13F I would contact LG and give them these numbers. Is your ballast bad or is the BallastEUC bad? Let me know if I can help you further.

chances are it's the one large fan in the rear of the unit. That's the most common to fail. Easy to do yourself. A $30 part and 20 minutes total to do, unscrewing with a Philips screwdriver, replacing the fan, and putting it back together...

I have a panasonic projection TV, PT-60C13 that will not turn on. Upon pressing the power on button, the button flashes green many times, then flashes red five time then one orange flash. This red/orange...


Hi,

The most common cause of Panasonic Rear Projection LCD TVs not starting is bulb failure. The PT-60LC13 users manual gives some help in translating the LEDs on the front of the TV.

If the TV worked normally for a period of time (months or years) and won't start, the most likely cause is bulb failure. There is no way to measure the bulb, sometimes the bulb is visibly damaged when it fails. Remove the Lamp Assembly and look at the bulb.

If there was an On-Screen Lamp Replace warning and TV won't start, bulb has failed.

The first step with all Panasonic Rear Projection TV "No Picture" problems is bulb replacement. If that does not remedy the problem, get a technician, there are no user serviceable parts. Guessing if the ballast, power supply, controller board or optical engine is faulty is not practical.

The Panasonic Lamp Gallery shows all Panasonic models and Lamp Numbers. There is also a link to Panasonic DIY bulb and lamp replacement.

How To Know if it is the Lamp, or Ballast, that has failed.


Hi There. This is a very common issue with most rear projection Televisions. For example, you and your loved one are watching a great, and captivating movie, but suddenly, the screen go's blank. There is a "Lamp" signal in the right or left upper corner of the screen, and its flashing. Im sure at this time, you are very upset, and your loved one is, as well. don't worry about a thing. I will explain what is actually going on in this situation. In most situations, this will be a blown lamp, but in others, this will be a failed ballast.

Ok, first we will go over a few symptoms. The first will be the "lamp"

LAMP FAILURE

The lamp has only one symptom of failure. this will be a single pop, or a faint overheated filament smell. Normally you will here a single pop before the screen will go blank. The sound may continue, in some models.

BALLAST FAILURE

The ballast is a little tricky to diagnosis, audibly. There are three main symptoms of failure here.

1. The TV will usually give a "LAMP" failure code, even when the lamp has been replaced.

2. The TV will not make the normal click noise, or surge noise during start up. The absence of the start up surge noise is one of the quickest ways to determine whether the ballast or power board are bad, other than the lamp, itself.

3. The TV will make erratic, or rapid clicking noises during start up(5 clicks for every 3 secs). This is an indication of a weak ballast. It is unable to power up the lamp.

Now. Once you are faced with this issue, I would advise to simply test the ballast. Once exposed, you can visually inspect the component's as well. I will guide you through this with my procedure below.

The Lamp, and ballast are housed in close proximity of each other in most rear projection DLP sets. There is an access panel located on the bottom rear side of the unit. Most standard Phillip head screw drivers will due. Once the screws are removed from the rear access panel, the panel can be removed, and put aside. Once the panel if removed, the internals will be exposed. The Light engine platform is where the engine, and lamp housing will be mounted. The lamp/ballast housing is slightly to the right of the light engine. It will be black, in color. Ok, gently unscrew the light engine platform screws,and separate all harness connection to the engine,before pulling the platform away form the cabinet. Make sure the wires going to the digital board are removed from the light engine Assembly, and lamp/ballast housing as well. It is very important to make sure that all wires are disconnected from the light engine, and lamp housing before the engine platform is pulled away from the unit cabinet. Ok, once the platform is removed from the unit, simply pinch the plastic clips and pull to remove the vent housing. Now, once the vent housing is removed, the ballast will be exposed. Pull the smaller connector (ballast control cables), out carefully. Be sure that you don't damage the connector or the cables. Ok, now you release the lamp housing, and remove it. It is just to the side of the ballast housing. Once the lamp housing is removed, the ballast will have a few screws holding it on the engine platform. Simply remove the ballast mounting screws, and lift up the ballast housing of the platform.

NOTE_Normally, the ballast has Two connections to the digital board and power supply. The third connector goes to the lamp. Connector one powers the ballast, while connector two, gives operation instructions to the ballast.

Ok. Once the ballast housing is removed from the platform, place it on a separate table, and remove the ballast housing screws to expose the ballast circuit board and components. This is where you will need to access a multimeter. testing is needed to confirm ballast failure. Although there are visual indications that will confirm failure, i would suggest to test as well. Observe the ballast before proceeding. If oil is leaking from the ballast, stop here and remove the ballast. Leaking oil indicates that the ballast is damaged beyond any doubt as the internal seal has been ruptured by excessive heat. This is one of the visual indicators that will require you to go ahead and replace the ballast. If there are no oil leaks visible, move on to the testing procedure. Turn the Volt Ohmmeter to "ohms" and touch the ends of the two probes together. The meter should show continuity or a direct short. Touch the probes of the meter to one of the white wires and one of the colored, blue or yellow, or any wires that comes from the ballast. This should show a short or continuous circuit. If it does not, the ballast is bad and should be replaced.

This will conclude the procedure. This will prevent you from purchasing the wrong part, when the "LAMP", code appears.

Here are a few other models that my tips will cover. HLT4675S, HLT5075S, HLT5675S, HLT6756W, HLR5067W, HLR5656W, HLR6767W, HLT5076S, HLT5676S, HLT6176S

DLP -RPTV lamp/ballast Failures


All, One question or comment that I have never seen on the threads dealing with multiple failures of the DLP Lamp and ballast systems is what is the unit installed in? How far is the cabinet from the wall? The units I have looked at haved forced fan cooling to beep the lamp from self destructing. On the HLP4663W if the unit is placed against a wall the exhaust (heated) air port is blocked. Too close to the wall and the heated air is recirculated back into the cabinet directly over the ballast module. It is possible that the lamp/ballast assembly is running too hot. Not hot enough to trip the safety circuits but hot enough to degrade the life expectancy of the unit and drastically shorten the life of the lamp and/or ballast. IMHO if the cabinet is close to a radiator or within 6" of a wall thermal problems will result. Just my 2cents. Zenith451

Picture won't come on. light flashes green continually, after 3 or 4 minutes the light flashes red continually. bulb is less than 6 months old. any ideas?


Hi:
This model was notorious for fan failure. The most common failure was the lamp temp fan. Its use to keep the lamp a constant temp. Also if one of the fans fail the unit will not start, This model is also known for Ballast failure also. The ballast is use to light the lamp. The best thing you can do is have a service technician come out and diagnostic the set for a minium fee.

There is a service manual, use the troubleshooting procedures, and you should be able to find out whats wrong. It could be your thermal fuse, or your lamp, or the ballast, so you will have to troubleshoot to find out.

Tv has no picture or sound. replaced bulb no help greenlight blinks 79 times. red lights start blinking


Lamp light flashing once every 5 seconds or twice every 5? Twice every 5 seconds,....lamp failure, once every 5 seconds,...ballast or thermal fuse failure. You have a lamp, ballast or thermal fuse problem. The ballasts are a discontinued part and can only be purchased used at approx. $225.00 or rebuilt for around $175.00 less any service charges to diagnois and repair.

Panasonic pt-50lc13 it just will not turn on,but the red light is on and the lamp was replace


Is the lamp indicator light flashing? A new lamp may not solve the problem. The known problem with lamp failures is poor voltage output from the ballast,.. a problem Panasonic refuses to correct and they decided to no longer provide the repair part through their supplier in an attempt to sweep this problem under the rug.

Not coming on, lights blink, but nothing happens


First thing to check is the bulb. On the back of the set is a hatch with four black screws. There is a TT symbol on that hatch, open it and you'll see the black lamp housing over the ballast circuit board. Remove the silver screw on the left of the housing and pull the aparatus straight out. It may stick a little, don't be afraid to give it a tug or two. Check the bulb, the part of the filament that burns is inside the glass tube that is near the base of the bulb bowl. If it looks broken or burned. Replace the bulb. Ebay sells them for about $100 or less. I've never had a problem with OSRAM vs Phillps, so whichever. Phillips is better but OSRAM does work too.
Sometimes you buy the bulb with the housing sometimes not. Its pretty easy to replace the bulb. You-tube it. Reverse the dismantle and see if it comes on. If not, we move onto the color wheel and ballast. Email me if this doesn't fix your problem and I'll help you move onto the next step. cfoley@hawaii.rr.com
Good luck.
