SOURCE: Flickering blue picture

I finally got around to dismantling the TV. This is no mean task. The chassis is tethered to the rest of the set my over a dozen wiring harnesses and a few of these cannot be disconnected near the chassis but instead require removing the “right support” near the air duct and taking the shield off the lamp ballast. Once the chassis assembly is out, it is a further significant task to disassemble it to get at the various PWBs (POWER, FMT and DM) having the suspect caps. I’m sure reassembling everything will be a fun job!

I have not yet had a chance to fix and reassemble but I wanted to post this no as I’m not sure when I will get around to it.

I did find six of the fourteen known-problem caps to be visibly bulging -- both 3300s and two of the four 1000s on the PWR PWB plus two of the four 1000s on the FMT PWB (see photos below). Ironically of the four 1000s on the DM PWB, which I have heard are the most common to go bad, were bulging and I considered skipping these as the DM it is the toughest board to extricate from the chassis, however I figured I had come this far and I would just as soon replace all twelve 1000 uFs as the parts cost $0.23 and I really never want to have to do this again.

If I had to bet, the two 10V 3300uF caps on POWER board, which were actually leaking black goo, are the actual culprits, but with four of the 1000 uFs also bulging it is probable only a matter of time until they failed as well.

Here is the POWER PWB with the known-problem caps (C9A37, C9A38, C9A51, C9A52, C9A61 and C9A62) highlighted:

here's the FMT PWB with the known-problem caps (C8F19, C8F21, C8F22 and C8F27) highlighted:

and the DM PWB with the known-problem caps (C81A2, C81A3, C81B3 and C81B4) highlighted:

Here are close-ups of the bulging caps (C9A37, C9A38, C9A52 and C9A62) on the POWER PWB:

SOURCE: samsung DLP TV won't turn on

This sounds to me like one of two possibilities. First, check your ballast. If you're going through bulbs faster than you think you ought to be, you may have a ballast that is overloading. Its the 3" x 8" circuit board that connects directly to the bulb. They are plentiful and often cheap. Thats what I'd try first. If that doesnt' do it, I would invest in a new power supply board. That the board that the tv power cable hooks directly in to. This should give you a start, Comment back if you still need further help. Good luck.

There's something wrong in the power source of the tv , very bad sign on a tv just 2 weeks old. Just take it back, not worth the hassle.

My 15 month Celcus LCD423D913FHD tv will not turn on. The standby light is lit and will flicker but will not power up the tv. What is the likely problem?


Fault with its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

No picture, sound works. Screen flickering


It sounds like the video output isn't
working its most likely a component
failure 1 thing you could try is connecting
a rca cables from video/audio out on the set to
another set vid/audio inputs to see if it the video gets
through.This is a problem that requires technical
knowledge and test equipment to trace the video

With no stand by light, you are not getting power.Unplug TV and check fuse on power supply. You will need a meter to look for shorted components and possibly leaky/bulged capacitors that are killing your power supply. flickering could be part of the bad power supply or possibly a problem with YSustain area of your TV

My emerson tv standby light is on the power light flashes twice


Mine stayed in stanby mode and all I had to do was to switch the plug to a different outlet. The power strip it was on wasn't providing enough power. It worked fine for a month before I had a problem.

Tv went black and no sound standby light falsh twice and paused and flashed twice again


This indicates a short happened somewhere in the set, causing the set to go into "safe mode" where it won't let itself turn on. Oftentimes it's the convergence board. Depending on what that will cost you, you may want to just replace the set.

Sony blinking standby light


This is Sony's way of telling you that there is a short in you set.Probably the horizontal deflection circuit.(Horizontal output transistor shorted??). Also any other short. You need to take it to a techincian and have it checked out. It would be wise to get an estimate! Stargazer
