Question about Sanyo DP42849 42 in. HDTV

1 Answer

Sanyo dp42849 picture is slow

When using it in any mode the picture fades in, then "smears" across the screen as if it is spreading the color. TV mode does not work at all, just random color across the screen. In PC mode the screen comes on okay but the mouse will fade out and move extremely slow across the screen. If any motion is used the screen will fade out from the old pic then in to the new pic or screen. In USB mode, hooked to a camera, the pics are okay but again it will fade out from one pic to the next with slowly fading ghost image of the last pic. It's as if it is working in slow motion.

Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.
http://electronicshelponline.blogspot.com/
To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

Most problems can be solved by replacing the power suppy. Try this first before you pay an outrageous price to fix it, I've had to repair 12 tv's that had problems from fading to flickering pictures. This most always indicates a power supply problem

Our TV shut off and won't turn back on. We have had it unplugged since 12-27-14 around 4:00pm and we plugged it back in 12-28-14 and it's still not turning on. Any suggestions?


If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

Try resetting, Not sure if this works for your model
Power off the TV, hold down the reset button on the remote and power up the tv with power button on tv while keeping reset depressed.
(Is there a restore factory setting or reset buried in the on screen menu? I couldn't find it in the manual, can you let us know if there is?)
here is the manual in case you don't have it

This is most likely going to be a color wheel. I would recommend checking on the color wheel first. If this is a dlp tv it could also be a lamp that went out.

My color started fading about 2 months ago NOW it its smearing and ghosting.I can turn it off and for a few minutes the pics fine and then its back to the same situation


I had a similar problem. Poor picture quality, and colors way out of balance. The problem: too much dust on the circuit board. I opened it up (remove 8-10 screws and don't forget the 2 little ones holding the coax/cable connection), gently vacuumed off the circuit boards (the bottom one and the one on the back of the tube). It works perfectly now, without ever repeating the problem. This may need to be done every few years, especially in dusty environments. It has also worked on my computer motherboard, and power supply. I think a build up of dust can cause a very weak short across the closely spaced circuits. Give it a try, it's free and you don't have anything to lose! Just be gentle.

The sound you heard came from one of the IC's under the heat sinks. Check the fuses on the left and right print, the print with the broken fuse must be replaced.

If the horizontal lines going through the picture are fine white lines, then I would suspect the picture tube as having a heater to cathode short or some other problem. Since some sets have had a 3 year warranty on the picture tube, you may be lucky unless the labor to replace the tube is more than the set is worth. Sanyo is usually not a good name in consumer electronics anymore, so if you're looking for a replacement I would look elsewhere.
