Question about Samsung LE40R73BD 40 in. HD-Ready LCD Television

1 Answer

Long wait when cold for tv to actually switch on

MY samsung 40in LCD takes so long to turn on, the red lights clicks on/of for several minutes before a coloured box appears in the left hand top corner then the picture comes on. Other wise everything is fine. I do have sky & Wii and surround sound connected and this only happens when the tv is cold or been off for a while.

Bad capacitors unplug the tv and let it sit for a day. Lay the tv flat and take all the screws out the back you want to look at the top right corner of the pcb ( power board you cant miss it ) you will probably notice 4 swollen / leaking caps replace these and the tv should work fine. The tvs protection circuit is stopping it from starting your straining the PSU by using it with the caps blown if your not comfy soldering phone a local electronics company im sure they can help you out. you can easily disconnect the headers from the psu board and take that for repair.

i used 35v 1000u caps the caps i removed were 10v 1000u

Why wont it turn on


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.

Samsung LN46A580P6F LCD HD TV is turning on and off from two to ten times before it stays on when the tv is cold


Samsung LN46A580P6FX
On the main board, IC104 (Part #SPX1587AT) is a 3.3VDC to 1.8VDC regulator. When this IC fails, the 1.8VDC drops substantially when the TV is turned on. After five minutes or so, the unit operates fine. This IC can be purchased from digikey for about $1.80.
Another fix is to attach a 1000uF 10 volts capacitor from ground to the DC source of this IC. I used a 1000uF 50V (overkill) for proof of concept. See attached pictures.

Samsung lnt4042hx/xaa 40in lcd tv wont turn on


I concur with Lightnbaby.... had same problem... my TV LNT4042HX/XAA took 10 min to start sometimes... the capacitors on the power supply board had bubbles on top 4 of them all 10/1000Uf. Samsung wanted to charge $220+ to have a guy come out and fix. J&J parts (samsung vendor) wanted $108 for a new board. I replaced the 4 capacitors for $4.68 and the TV works fine now!!!!!
