You're discussing about the supply load resistor, I assumes, and posts this solution. In most cases, it will be better to replace the power supply regulator board as card basis, rather than trying to make it repaired.

I'm not sure if this model is the one that has resistors that go bad. You can actually purchase a pack of resistors in a kit. It will come with solder, the resistors and instructions. You can lay the tv out and take the circuit board out to find the blown components, and replace the bad ones. Takes about an hour start to finish and will cost around $65.00. It has been a few years since I did this, so I'm not sure on the price.

PANASONIC TH-42PX60U 42 - half of screen not working


I had the same issue. I am going to replace my scan buffer boards. The upper half of mine works but the lower half is black so I would replace the lower Scan buffer board but in case of future issues I have ordered both upper and lower for $44.
The scan buffer boards are fairly simple to locate. Open up back of tv there are two biffer boards identical. The item or product code on them contain letters either SU or SD (Scan up and Scan down)Look up tv parts and item code you will find a place to order or just get the 1 800 number from tv manufacturer.

My TV Screen Has Internally Cut in Half?!


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..

ICs + resistors swapped= blue power light auto on clicking noise


Unplug the power to the convergence board. If it turns on, you still have a problem in the convergence circuit.

Power Light blinking 5 times


check the resistors near the
stk's. There are some reports that they get fried when the stk's fry....or the other way around. The resistor ratings are labeled on the resistors. 2.2, 82, 180 or something like that. Also check the board as you turn on the tv. See if any glow red.

No Picture Has a bright horizontal line with off white & gray vertical bars


The Problem Philips 27TS54 c101 27B800-7562 White horizontal line in the center of the screen. Color is present in the first half inch of the leftist corner of the horizontal line.
Audio is present and controllable. The green power led from a cold non plugged in state remains solid until CRT goes to ignite. A click is heard then the green power LED blinks.

Possible Answer Posted by PEE_WEE 4/28/2005
On the CRT circuit board(picture tube), you will find R3340, which is a 10 ohm 1/3w resistor. The location of the resistor is printed on the bottom of the ckt board. It is burned open, replace with a 10 ohm 1/2w resistor. This will solve your problem. The original resistor was sized too small, should have been a 1/2 watt. This resistor is mounted standing up on ends. Mount the replacement resistor the same way. Be careful and don't get the circuit trace too hot and damage the circuit trace. (it's very small) The resistor is located on the crt(cathode ray tube), pcb(printed circuit board) socket. The resistor supplies apx +200v to the collectors of the r, g, b, video driver transistors. If this voltage is low, it causes excess brightness(excess beam current), causing the set to "shut-down". If the shut-down is too quick, you will NOT see the excess brightness, because the picture tube has not warmed-up enough to display anything on the picture tube. To see if the set displays "excess brightness", you will need to turn the set "on" about 5 to 10 times. This will heat the picture tube enough to display "excess brightness", IF that is the PROBLEM. Of course, there are OTHER defects that will cause a tv to shut down. There are built in safety circuits, that will "activate" if excess voltage/current or heat is detected anywhere in the set.

NOTE
My resistors are not numbered the same on my crt board APT187. GSM 02/20/2008

Hitachi 43FDX11B television Ghosting


I had the same problem on my Hitachi rear projection TV 53FDX20B made in Mexico. The blue convergence problem. Blue focus had shifted and appeared like a blue ghost image. I followed the step by step intructions from the fixya site. First Replaced the two STK 392-110 ICs and turned on the tv. No change. Then I went looking for the bad resistor. There was one resistor RK50 (2.7 ohm, 1Watt capacity) which is attached not right close to the printed circuit board surface but was well raised up from the board. The bands on the resistor were a little discolored. I replaced that one and turned on the tv. The convergence problem was solved. Thanks for the step by step instrucitons on your site.

Sounds like the circuit board may need to be replaced. Mine did a similiar thing only my picture turned upside down, screen went blank yet had good voice. Samsung tech said the 2 circuit boards were bad and had to be replaced at a cost of $780 in parts plus labor. I bought a new LCD TV, not Samsung.
