Black or just sagged apart? If the latter, I would try a new fuse and see what happens...accordianman

hi,
You have to check the lamp ballast supply board. If the Lamp ballast board is faulty the it will burn the new lamp installed. 5 blinks means the lamp is faulty. can be caused by faulty lamp ballast. To deal with the lamp ballast you should need a good knowledge in electronics. Because electric shock risk is involved. Also you need a new lamp
ok

Okay, so my Panasonic PT-43LC14 went black in mid show last night. The bulb is approximately 18 months old. The LED indicators upon Power On are; Power LED blinks green for approximately 70 seconds; Then...


Check the bulb again and look at the root of where the main stem comes out inside and be sure you don't see any bubble like appearence around the stem at the bottom there. If you do see this then the bulb is bad. Otherwise try this: Hold volume down on front of unit and pip on remote for about 5 seconds. Message will come on screen that timer has been reset to zero. This sets the lamp timer to 0

My KDS-50A2020 TV has an error code indicating a lamp driver fault (5 red blinks). I replaced both the lamp and the ballast and it still doesn't work. I need further assistance troubleshooting the...


Hello.
Ballast in Sony is one of the most reliable parts, almost never goes bad.
I assume you have TV unplugged from the wall outlet to reset error memory (not to mention that you have to do it anyway during ballast replacement).
I hope you are using good quality lamp, because cheap substitute from E-Bay can cause same problem. Lamp and ballast works as duo and on-board diagnostic system is unable to separate them unless lamp is completely blown (in that case you will have steady "Lamp" LED blinking).
You need to set TV up with back cover removed but lamp door attached (there is switch that prevent TV from working if lamp door is removed). You need to locate large 2-wire connector on ballast and make sure that it's getting about 330V DC from power supply board when you turning your TV on. If it's not there - you have power supply board problem. There should be fuse on it (not on the ballast board but power supply board - just trace those two thick wires where they coming from). That fuse could be blown by previous bad ballast shortage.
Small connector on ballast have 5 pins. Some of them ground, one of them steady 5V and another trigger (turn on signal) 5V. Make sure all voltages are there. If there is no trigger 5V - you have problem with main board.
In my experience 90% cases - it is very bad quality new lamp or something is just not connected (forgot to put plug all the way or something).
Good luck!
Russ.

Mitsubishi WD-57732 LAMP continuously burns out. I have replaced four in two years. We don't watch alot of TV.


There are a few issues here:

The lamp you are purchasing could not be OEM, or a compatible lamp--OR you have a ballast/power supply issue blowing the lamp out.

The original lamp is manufactured by Osram, but a better and compatible lamp would be Philips, who pioneered the lighting for DLPs. The ballast needs to be compatible with the lamp and Mitsubishi ballasts are compatible with most lamps, but work best with Philips and Osram. Only buy from an authorized dealer!

HOW TO REPLACE LAMP


Check on You Tube there is a video that will walk you through it. Be sure it is the lamp that is the problem before you spend your hard earned money.
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.

I changed the lamp of my tv but still dark


The Ballast, or "ballast booster" is sometimes the culprit, gives the same symptom as a burned out lamp. Make sure your main power fuse is not blown first.

Replaced the lamp on 50v710 keeps on burning out


You have a bad Ballast. This can be repaired sometimes by replacing the capacitors on the Ballast circuit board.

New Lamp will not come on


I suspect thermo fuse near lamp or ballast or light engine. In that order , first double check lamp is in tight and covers are on correct there are switches on cover for lamp.

1 thermo 150.00
2 ballast 250;00
3 light engine 600.00

Get a tv service center to come over and check. it would be worth the service call ask him what he charges for road call , at least know you have price and part information.

Vulb,
Having had to change the lamp I would suspect the lamp thermal fuse is open... It's located over the duct for the fan housing and solders into the ballast board.. Check it for continuity and if open replace it..
There are several thermal fuses in that unit and not all of them as easy to access as the lamp one.
Good Luck
Bill
