Replace the convergence board. you can get it from VanceBaldwin.com. The part number is BP95-00142E. Easy install. You can test this TV before you buy the part.

If you take off the lower back of the TV, you'll see the board mounted near the middle of the TV on the right. On mine the power connector is red. Unplug that connector, replug in the TV and turn it on. It should come on, but the picture will be a mess as the tubes won't converge (obviously).

Plug in the new board, and keep right on going... $78 delivered. Took three days.

Timer light will not stop flashing. can't turn on TV


Unfortunately the first generation DLP's from Mitsubishi are prone to have Capacitor failure through out the chassis. Most likely that is what your set is experiencing. I would start by replaceing the suspect caps on the DM amd The Power boards. You can get the V26 Chassis DM/Power repair kit from www.tvrepairworld.com which also contains instructions.

I have a samsung hlp5063wx. I just replaced the color wheel. It worked fine for two days. Then no picture or sound. After I turn the tv on the lamp LED on the front flashes. Then it goes thru its cycles....


If the color wheel doesn't spin, the lamp will not fire. The lamp has a gap in it, it will read open. Pull the rear cover off trip the door switch and look close and listen. Double check that the color wheel does not spin up (turn on, then wait 5 secounds or so.. pull the power cord and listen for it to stop.. best method). Also, watch the lamp driver.. there is a condensor coil on there that will lite up when it is sending the ignition pulse to the lamp... do you see it? If so, it's the lamp.

Tv wont turn on get audio then tv shuts off timer lite blinking


If TV stays in stand by with audio but no video, then common faults are the ballast board, or a fault on digital board.

If the led stays blinking , and tv turns off then the TV is on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.


If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.


If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

Timer light is flashing but tv wont turn on!


When the timer light stoped flashing the remote control would not turn on the TV. The next time the light quit flashing I held the power button in on the TV for about 5 seconds and it came on and has had no problems since then with the remote or the local TV power button.
