Question about Televison & Video

1 Answer

I have a sanyo CE27LD-3B with sound but no pic. The back light is working, and there seems a lot of activity on the input to the panel drive pcb from the main pcb for example when I change channel the waveforms change. I have little experience with LCD, but greater experience with Plasma, as I am a repair technician at Pioneer. I suspect the panel drive pcb is at fault, the equivelent pcb on a plasma screen would be the digi or the sequence dridrive pcb. Thank you for your assistance. Gary Banks

Screen driver fault sounds like. could also just be the lead from the av board to the screen driver board or its connector, if you wiggle the cable see if the screen reacts with the wiggle.

SOURCE: screen went out

I had the same problem, but I had no sound at all. The power indicator light was flashing green. I tried to unplug the unit and plug it back in, but the light then was red briefly, turned orange then flashing green. What I did to solve the problem was to unplug the set and leave it for a few minutes then plug it back in and hit the front power switch at the same time. Voila! It started working again. Good luck solving this.

SOURCE: lite blue cloud and blue spots

It might be just dust somewhere in the light path to the LCD panels or on them. The only other thing that comes to mind is the light engine itself and that is no easy task to replace. The part number for it is A-1084-666-A and can run close to 1000.00 for the part. Can you post a picture of the issue so I can look at it?

SOURCE: Pioneer plasma media receiver problem


The Pioneer multi media reciever box is only serviceable from the manufacture. They should have authorized service reps that they equiped to do service for Pioneer devices. They normaly change boards to service it. The regular service man would only be able to fix a simple cold solder connecton or fix some other simple part of it.

Contact the place where you bought it to find out about servicing it. You may find it cheaper and easier to simply replace it completely. It is very possible that there is no service support for this box. Get an estimate before accepting to service it.

Most of the small electronics of today are throw-away anyways...

Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

Sanyo DP42849 no picture but has sound


Sounds like an inverter problem. On some of these sets, the inverter and the power supply are on the same board. These boards tend to be quite pricey, $100 + range. I've worked on your particular model with the same problem, and it was a bad inverter/power supply board. I would recommend you get a diagnosis to be sure.

Sanyou DP26746 LCD TV Has sound, No picture, Has backlights, LCD is active


It sounds that the main digital board to your TV has damaged. But, before make it confirm, a through check should be done. Contact any experienced service technician for help. The work is skilled one, that a user cannot do it with ease.

I have a Whirlpool Refridgerator model WBM39MS. It stopped cooling and I had it repaired. The Repairman replaced the electronic control box. Repairer claims that the compressor is working. It now seems...


Hi Lollipop, partially working fridge? A fridge either works or not, cold air is made in freezer then distributed to fridge via a vent. In your case WBM Series fridge, top mount freezer blows air down a vent (back centre of chiller compartment). A common fault with the WBM Series is both the PCB and Interface Panel (PCB beside compressor back of fridge, Interface is display panel front of fridge).
So if freezer is cold and fridge not, try a fan motor. If compressor doesn't work either comp is faulty or PCB has blown(has a burning smell).. Hope this helps you and maybe many other ppl.

50 inch Sanyo Vizon Plasma TV. Has sound but no picture for last few days. 2 years old


This set has LG insides, it will have failed on either the Y-Sustain PCB or the Z-Sustain PCB.

Quite common.

Repair estimates should be $250 - £350 depending on which has failed.

Stick it on eBay, it will fetch good money faulty.
