I have a Mitsubishi 65 inch TV. It is model number WD 65735. The TV will not come on and it has a yellow blinking light(lamp) on the front of the TV. I purchased another lamp assembly and installed it but it does the same thing. I am looking for some help.Thanks.

Re: Mitsubishi TV
My guess is most likely ballast failure, check to make sure the board is getting the required voltage from the power board (Should be marked on the board, about 380v) there are lots of "kits" to fix these on ebay. Usually the diodes are the culprit, you can test them with a multimeter on diode mode.Liberating magic smoke one part at a time -
Re: Mitsubishi TV
You can get a service manual for this set here (you have to wait a few seconds for the link to appear in tiny text before you can open the manual)
Blinking yellow (on the lamp led) indicates that the bulb cover is open. Always nice to have a service manual(Bulb cover is actually accessibly from the back of the set ... it's a little door, you might have mangled the sensor for the cover when you removed the door, I know on projectors many people ruin the sensor)

This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....-

by mikey5791Hi,
This monitor previously is my main working monitor which i have been using for 8~9 years. Yesterday, when i switched on my pc from fresh to power on, the monitor is just black no display. I started dismantle to look inside the monitor power board but nothing looks suspicious or burnt. So i took my external ccfl inverter to try to power the monitor ccfl lamps which consisted of 2 lamps on upper part and 2 lamps on the lower part.
Found out the upper ccfl lamp which is supposed to connect to cn304 on the power board did not light up. Then i installed a used working...-

I have a big problem and that is that in some cases when repairing active pfc power supplies I cannot work with a test lamp. I can only get help with 5 volts standby and for starting and starting I have to work without a lamp and this way there is a possibility of parts exploding and other parts being added.
Sometimes with a multimeter test the problems can be reduced to some extent, but I had several cases that had to be tested on and online and recently two varistors exploded. They had terrible resistance because the power supplies were over 800 watts.
Is there a way... -

I have a weird problem with an old Philips 37pfl560 TV i put out of storage: the picture have a noticeable yellow hue, and its not caused by the settings (did a factory reset). I've never seen this before. I will try to get a photo with a real camera, with my phone its hard to see because of automatic white balance, but in real live the whites are really yellow.
Anyone have an idea of what can cause this? Can CCFL tubes get "warmer" with time? This tv have several analog inputs,so its nice for retrogaming.... -
by nick3092I recently acquired a set of Bose Roomate speakers from the mid to late 80's. Basically the right speaker cabinet is completely passive, and the left one has the power transformer and amplifier circuit in it. Out of curiosity, I opened it up to see what the circuit looked like. Looks like they used all Nichicon VX (2x 4700uF/16v for smoothing off the bridge rectifier), a couple random Nichicon SE series sprinkled on the board, and what really caught my eye - 2 yellow sleeved Nichicon caps (both 1uF/50v with no real series marking. Below are pictures of the caps. The only thing not shown in these...
